GENERAL REQUIREMENTS
总体说明
The Safety Interlock System for the Oxygen Mixing Station (OMS) should be designed as “Fail-safe” system, i.e., failure of any component in the loop such as primary field element, transmitters, alarm blocks, etc. should cause a shutdown.  It should be recognized that the logic is only one aspect of obtaining a “Fail-safe” system.  The overall integrity of the “Fail-safe” design should be ensured by the hardware as well as the system implementation.
氧气混合站(OMS)的安全联锁系统必须设计为“故障安全型”系统,即回路上任一元器件(如测量元件、变送器、报警模块等)产生故障时,必须引发联锁动作。联锁逻辑只是“故障安全型”系统的一方面,硬件和软件共同确保故障安全设计的统一完整性。

All of the OMS interlock logic (including the cycle gas vent logic) should be implemented in a dedicated Programmable Logic Controller (PLC) system with redundant Central Processing Unit's (CPU's). These units are provided with automatic alarm block over from main to backup CPU within one processor cycle time (typically less than 20 milliseconds) of fault detection.  After the main CPU fault is corrected, the system is manually alarm blocked back to the main CPU. Each processor should be provided with an independent power supply with no common elements other than the uninterruptible power supply (e.g., fuses, circuit breakers, alarm blocks, power cables etc.). The Recycle Compressor logic MUST be totally independent of the OMS interlock logic to avoid common mode failure.  The Recycle Compressor logic and the rest of the plant interlock functions should be implemented in a dedicated PLC systems (other than the OMS PLC) also provided with redundant CPU’s, arranged redundant to run.  Total response time for each OMS interlock loop (Starting from the primary field element to the final control element, including the PLC and all other hardware in the loop) MUST not exceed 700 milliseconds.
所有的OMS联锁逻辑(包括循环气放空逻辑)必须在具有冗余CPU的PLC系统上执行。系统在检测到主CPU故障的时候必须能够在一个处理器周期时间内(通常少于20ms)自动切换到备用CPU。主CPU故障排除后,手动切换回主CPU。每个处理器都应有独立的不间断电源提供,电源之间不应有工同的元器件(如保险丝、空开、报警模块、电源电缆等)。循环气压缩机的逻辑与OMS联锁逻辑必须完全单独完成,以防止共用模块故障。循环气压缩机与OMS除外的其他联锁功能应该有单独的PLC系统(独立于OMS的PLC系统),该PLC系统同样必须是冗余的。每个OMS联锁回路总的反应时间必须不超过700ms(总反应时间是指从现场监测元件到最终控制单元的时间,包括PLC和回路中其他所有硬件)。



The PLC programmer should be removed from the PLC CPU prior to plant start-up and not used during operation under any circumstances.  If changes to the interlock logic are required, or if the PLC is to be used for moving valves for maintenance purposes, the battery limits oxygen valve should be closed and the IBL oxygen line and any surge drums and filters should be de-inventoried and purged prior to re-connecting the PLC programmer.
在开车前PLC程序必须从CPU中移除,并且在操作过程中,任何情况下都不能使用。如果需要联锁逻辑或者通过逻辑动作需要维修的阀门时,必须关闭界区的氧气阀门,氧气管线和缓冲罐、过滤器需清空,并在重新启动前要先吹扫。

External Master Control Relays (MCR) should be used to control the power supply to the critical output devices for the OMS PLC.  Non-UPS commercial power for all the critical PLC outputs to solenoid valves should be connected in series through the normally open (NO) contacts of the first MCR and normally closed (NC) contacts of the second MCR.  PLC output to the first MCR should be connected through the normally open (NO) contacts of the PLC system internal fault detection relay. The internal fault detection relays from each CPU should be connected in series to the MCR circuitry.  If UPS back-up power is provided for the critical solenoid valve outputs, then an independent general power failure interlock should be provided to shutdoown。

SD recommends using single set of interlock inputs connected directly to the PLC system (with no parallel connection to other devices) and a hardwired output connection used to repeat the critical signal to the DCS, and/or light/annunciation.  Communication data transfer between the PLC and the DCS must be secured redundant and should be used only for the non-critical signals.  Analog PLC inputs must be dedicated and fail-safe by using self-testing input cards separate for each function with a separate input check.  
SD建议联锁输入采用单设备直接接到PLC系统(中间不加二次元件),关键信号的输出应硬线连接到DCS及声光报警器。PLC与DCS之间非关键信号可以用数据通讯方式传递,必须是冗余通讯模式。模拟量输入必须采用专门的,具有自检测功能的故障安全的卡件接收。

The interlock logic shown for package units is typical and is included to show interaction with process requirements.  The logic diagrams and Input/Output (I/O) listing is based on implementing the logic for the Recycle Compressor,  the Reclaim Compressor and other interlocks in PLC II.
包设备单元的联锁逻辑图是一个典型示意图,主要体现了装置过程的要求。循环气压缩机的联锁逻辑图和I/O清单以最终完成的逻辑为准,回收气体压缩机和其他联锁逻辑见PLC II。

Other arrangements, such as using local logic devices included with the package unit are equally acceptable as long as the process requirements are fulfilled as shown.  
只要工艺过程要求可以按要求完成,其他的设置,如用现场逻辑设备完成包设备单元也是可以接受的。

All the critical shutdown pre-alarms, sequence indicators, and push-buttons associated with the OMS start-up and automatic shutdown should be “hardwired” to a dedicated push-button console and annunciator panel.  The “first out” sequence of events should be generated in the PLC and displayed on a graphic screen in the Control Room.
所有关键联锁停车的预报警、顺控指示及与OMS相关的开车/停车等按钮应有辅助操作台可以显示或操作。首出事件须在中控室的操作界面上显示。













DESCRIPTION OF REACTION SYSTEM INTERLOCKS
反应系统联锁描述
To assure safe operation of critical units of the plant, they are provided with automatic interlocks designed to carry out failsafe shutdown of these units when safe limits of operation are exceeded.
为保证装置重要单元的安全操作,当相关过程量超出安全限值时将会自动产生联锁来实现故障安全停车。

The logic built into the Interlock System incorporates the following considerations which are enumerated according to the sequence in the interlock write-up:
构建到联锁系统的逻辑应注意以下一些事项:

1The tracking alarms serve to maintain critical alarm set points at a safe setting, irrespective of the plant operating capacity.
跟踪差报警的联锁报警设定点应维持在一个安全的设置上,而不考虑装置操作能力。
2The plant can only be operated with at least one of the two inlet oxygen analyzers on line. This allows calibration of the other analyzer.
反应器入口处设置两台氧气分析仪,只要有一个在线工作,装置都能够正常被操作;而离线的氧分仪可以标定。
3The Recycle Compressor must be running before oxygen can be introduced into the reaction system.
进氧前,循环气压缩机必须运行。
4The Boiling Water Reactor Systems must have a minimum level of water in the Reactor Steam Drums before oxygen can be introduced.
进氧前,反应器汽包必须有一定液位。

5The Reactor Gas Cooler Steam Drums must have a minimum level of water before oxygen can be introduced.
进氧前,反应器气体冷却器汽包必须有一定的液位。
6.         If there is a stoppage in the cycle gas flow prior to an oxygen shutdown, the cycle gas will be vented to purge possibly excessive oxygen concentrations.
如果循环气系统在氧气停车前停止,则循环气必须放空去吹扫可能有的过大的氧气浓度。
On start-up, the venting feature can be bypassed until the compressor is on line and the First Oxygen Block Valve is opened during the OMS automatic start-up sequence.
在开车阶段,放空可以被旁路,直到OMS自动开车顺控运行到循环气压缩机正常且 第一道氧气切断阀打开。
7The protected output devices (MCR’s) must be energized.
保护继电器MCR必须励磁。
8.         The initial valve positions in the OMS are set to:
a.         vent portions of the oxygen feed line
b.         block the flow of oxygen to the OMS spargers
c.         insure separation of oxygen and cycle gas by pressurization of a section of oxygen line with nitrogen to a pressure higher than either oxygen or cycle gas line pressures.
  OMS中的阀门初始位置设置:
A.部分放空氧气进料管线
B.阻止氧气进入OMS喷射器
C.确保
9During start-up the OMS has to be purged and pressure tested, and the associated alarms (pressure, flow and differential pressure) checked.  These specific alarms assure sufficient nitrogen purging to prevent cycle gas from entering the oxygen line.  This testing operation is carried out by purging nitrogen through the OMS spargers and selectively closing the proper blocks valves.
开车期间,氧混系统必须吹扫、耐压测试,必须检查所有相关的报警(压力、流量、差压)。必须保证足够的氮气吹扫以防止循环气进入氧气管道。这些个测试是由氮气吹扫过氧混站分布器及选择性关闭一些阀门来实现。
10The nitrogen bottles have to be pressured and the associated block valves tested for leaks. The pertinent section of the oxygen line has to be purged and pressurized with nitrogen. The associated pressure and flow alarms have to be checked. Nitrogen is then allowed to flow through the spargers to the cycle gas system.
氮气瓶必须加压,相关切断阀门做泄露测试。氧气管道相关部分必须通过氮气吹扫、加压;检查相关压力、流量报警。而后,氮气流过分布器进入循环气系统。
11Oxygen has to be first introduced through the smaller and then the larger of the OMS spargers. The design of the two spargers assures sufficient velocity under turndown conditions and full production to prevent backflow of cycle gas into the oxygen line.
氧气顺次经由小分布器、大分布器进入氧混站。大、小分布器的设置是为了保证氧气有足够的速度,以防止在翻转和全能力生产的情况下循环气进入氧气管线。
12As soon as the oxygen flow reaches sufficient quantity to satisfy the low differential pressure alarm across the OMS, start-up purge nitrogen flow through the spargers is stopped.
当OMS进出口差压低低报警消除时,停止开车的氮气吹扫。
13  In an emergency shutdown of the OMS caused by any of the interlock trips, the automatic sequencer will move all valves in the proper order.
任意联锁条件引起OMS紧急停车,顺控器按一定顺序动作相关阀门。
A total of six valves in series (five at the OMS and one at the plant battery limit) will separate the oxygen supply from the cycle gas.  Two vents from the oxygen header will open and establish an atmospheric pressure zone.  Nitrogen from four supply lines will first purge the OMS and then establish an atmospheric zone in one part and pressurization with nitrogen in another part of the oxygen line, separating the oxygen supply and the cycle gas system. In addition, a shutdown will also close the ethylene feed, ballast methane feed, inhibitor feed and argon vent valves.  If the Recycle Compressor caused the shutdown, the cycle gas vent will open for a brief period of time.
顺序排放在氧气管线上的6个阀门(5个在氧混站,一个在界区)将中断氧气供给到混合循环气中。氧气放空阀门打开,从而建立一个大气压区域。四条氮气供应管线首先吹扫氧混站,然后在一部分氧气管线上建立大气压区,另外一部分管线用氮气增压,从而隔离氧气和循环气系统。另外,联锁停车还将关闭乙烯进料,甲烷进料,抑制剂进料和氩气放空阀门。若是循环气压缩机引起的停车,则循环气将会短时间放空。

14In a normal shutdown, the operator will first reduce the oxygen and ethylene concentrations to the desired level for shutdown and then use the emergency shutdown button for the automatic sequencer to move all valves in the proper order.
正常停车时,操作员首先应该减少氧气和乙烯量,直到停车时期望的含量置,然后用紧急停车按钮使顺控器按一定顺序动作相关阀门到相应位置上。

TRACKING ALARMS - DESCRIPTION
跟踪报警

There are two (2) flow alarms of the tracking differential type which activate interlock shutdowns of the OMS.  These differential alarms, in which the alarm points vary by a fixed ratio from the process flow, are:

FDALL-1611 Cycle Gas Differential Flow Alarm FDALL-1563 Oxygen Differential Flow Alarm
循环气流量跟踪差报警FDALL-1611和氧气流量跟踪差报警FDALL-1563都会引起OMS联锁停车。跟踪差报警设定值与过程实时量成固定的比例。

In the case of the cycle gas differential flow alarm, the alarm setpoint will automatically increase at its fixed ratio below the process flow as the process flow is increased.  However, the alarm setpoint will not decrease when the process flow is decreased unless the "reset" push-button for the alarm is pressed.  Failure to reset the alarm setpoint when reducing the process flow could result in a shutdown because the alarm setpoint would remain at a value equal to the set ratio below the maximum process flow which has been obtained. Consequently, when deliberately reducing cycle gas, the "reset" push-button should be pressed and held until the new process flow has stabilized.  The alarm setpoint tracks the process flow while the push-button is pressed. Upon release of the "reset" push-button, the alarm setpoint is reset to the fixed ratio below the new lower process flow.
循环气流量差值报警FDALL-1611:
当循环气流量增大时,报警设定点按照固定比例随着循环气增大而增加;当循环气流量减少时,报警设定点维持不变,仅当“复位”按钮按下,报警设定点重新按固有比例计算。在循环气流量减少时,如果没有复位报警设定点,则有可能引起联锁停车。因为此时报警设定点将维持在之前按大流量计算出来的值。所以,如果需要减少循环气流量时,必须一直按着“复位”按钮直到建立新的过程流量。当“复位”按钮触发的时候,报警设定点跟踪过程流量。

In the case of the oxygen differential flow alarm, the alarm setpoint will automatically decrease at its fixed ratio from the oxygen flow rate as the oxygen flow rate is decreased.  However, the alarm setpoint will not increase when the oxygen flow rate is increased unless its "reset" push-button is pressed.  Therefore, the "reset" push-button must be pressed when the oxygen flow rate is deliberately increased.  Failure to use the push-button while increasing the flow rate could cause a shutdown of the OMS.
氧气流量差值报警FDALL-1563:
当氧气流量减少时,报警设定值会自动按与实时流量的固有比例减少;当氧气流量增大时,报警设定值不会变化,直到“复位”按钮被触发。因此,在需要增大氧气量的时候,必须一直触发“复位”按钮,否则可能引起OMS联锁停车。

In either case, the "reset" push-button must be kept pressed until the process flow has stabilized at the new setting. If not held until the flow has stabilized, the alarm setpoint might be set at some transient value rather than the desired value.  Premature release of the "reset" push-button will result in a high or low alarm setting too close to the new process flow.
无论哪种情况,“复位”按钮必须一直触发直到建立新的稳定的流量值,如果没有,报警点可能不在期望的数值上。太早释放“复位”按钮也会导致报警点太高或太低。


OXYGEN ANALYZERS - CALIBRATION
氧分仪---校准
A.Inlet Oxygen Analyzers (Logic # SD-OMS)
入口氧分仪
Logic Diagram D-708

      
If it is desired to service or to calibrate the Reactor Inlet Oxygen Analyzer, AIT-1501 or AIT-1502, then the selector switch HS-1500 must be set to that analyzer.  The selector switch, HS-1500 bypasses the high-high Oxygen interlock, AAHH-1101 or AAHH-1102 of the analyzer selected by HS-1500.  Red lights on the auxiliary panel and in the analyzer house indicate the one being serviced or calibrated. Green lights corresponding to each analyzer UI-1501A and UI-1502A on the Auxiliary Panel and UI-1501B and UI-1502B in the analyzer house will indicate when it is safe to switch the analyzers.
反应器进口两个氧分仪AIT-1501,AIT-1502,如果要更换或维护氧分仪,必须将旁路选择开关HS-1500选择到需要更换或维护的那台,将高高氧气浓度联锁AAHH-1101或AAHH-1102旁路。辅操台及分析小屋中的红灯表示该台表正在被维护。每台表都有一绿灯信号UI-1501A和UI-1502A,用于指示表状态良好,可以选择投用。
Low flow switches FAL-1501A, FAL-1501B, FAL-1502A and FAL-1502B are provided in the process gas sample line and at the analyzer cell of each analyzer.
       每一个氧分仪的采样管线和分析管线上都设置低流量开关报警FAL-1501A,FAL-1501B,FAL-1502A,   FAL-1502B。

B.Outlet Oxygen Analyzers (Logic # SD-OMS)
出口氧气分析仪
Logic Diagram D-706

When it is desired to service or recalibrate the Reactor Outlet Oxygen Analyzer AIT-1310/AIT-1410 the selector switch HS-1310/HS-1410 should be put in the "bypass" position. This will bypass the High-High Oxygen Concentration Alarm, AAHH-1310/AAHH-1410. Red lights UI-1301A/UI-1410A on the Auxiliary Panel and UI-1310B/UI-1410B in the analyzer house indicate that the corresponding analyzer is being bypassed.
要维护反应器出口氧分析仪AIT-1310/AIT-1410时,需先将选择开关HS-1310/HS-1410置于“旁路”位置,旁路高高氧气浓度报警AAHH-1310/AAHH-1410。辅操台上红灯UI-1301A/UI-1401A及分析小屋内红灯UI-1301B/UI-1401B指示相应的分析仪被旁路。

Low flow switches FAL-1310A, FAL-1310B, FAL-1410A, and FAL-1410B are provided in the process gas sample line and at the analyzer cell of each analyzer.
      每一个氧分仪的采样管线和分析管线上都设置低流量开关报警FAL-1301A,FAL-1301B,FAL-1401A,FAL-1401B。

3.Oxygen Permissive Start
进氧允许条件
Logic Diagrams D-707, D-709A, D-709B
With the Recycle Compressor running and water levels established in the Reactor Steam Drums and the Reactor Gas Cooler Steam Drums but before oxygen can be introduced in the OMS, the plant conditions must satisfy the Oxygen Permissive Start circuit which is hereafter referred to as OPS.  This is achieved when the alarm conditions listed in Section VIII, Emergency Shutdown, are satisfied in the normal state.
循环气压缩机正常运行,反应器汽包液位和反应器冷却器汽包液位满足后,在进氧前仍需要满足OPS中要求的氧气进料允许条件。VIII部分列的报警情况和紧急停车状态都正常的情况下,允许条件也就满足了。
The interlocks that are related to the Reactors and its associated equipment are as follows:
反应器的相关联锁和相关的设备如下:
a. Low-Low water level Reactor Steam Drums, LALL-1103/1203.
反应器汽包液位低低,LALL-1103/1203
b. Low-Low water level Reactor Gas Cooler Steam Drums, LALL-1316/1416.
反应器气体冷却器汽包液位低低,LALL-1316/1416

反应器汽包出口压力偏差高高,PDAHH-1102/1202
4.         Oxygen Permissive Start (Continued)
Logic Diagrams D-707, D-709A, D-709B
The Reactors inlet Motor Operated Valves (MOV’s) MV-1511 and MV-1521 and the Reactors outlet MOV’s MV-1710 and MV-1720 are not closed for the operating Reactors. The reactor outlet MOV must be fully opened prior to opening the reactor inlet MOV (Logic Diagram 5139-D-712B).  A green light on the Auxiliary Panel will indicate that the reactor outlet MOV is full open.  The reactor inlet MOV must be closed before the reactor outlet MOV can be closed (Logic Diagram 5139-D-713) (see Section IX, Logic # I-1132/1232 and I-1710/1720).

Green lights on the Auxiliary Panel UI-1710A and the DCS UI-1710B will indicate which Reactor permissives are satisfied.  A red light ZI-1511BA on the Auxiliary Panel and a red light ZI-1511BB in the DCS will indicate that MV-1511 is closed.  A red light ZI-1521BA on the Auxiliary Panel and a red light ZI-1521BB in the DCS will indicate that MV-1521 is closed.  
      反应器R-110的进、出口电动阀MV-1511和MV-1710,反应器R-120的进、出口电动阀MV-1521 和MV-1720。要投用的反应器,其进、出口电动阀不能关闭。反应器出口阀门全开后才能打开反应器进口阀门,辅操台上绿色灯表示电动阀全开。反之,进口阀门全关后才能关闭出口阀。UI-1710A和UI-1710B指示条件满足的反应器。


4.Bypass the Cycle Gas Vent System
循环气体放空系统旁路
Logic Diagram D-705
During the preliminary operations, prior to the introduction of oxygen, the bypass push-button, HS-1564BS in the cycle gas vent valve XV-1564 circuit may be activated. This will prevent automatic venting of XV-1564 should the Recycle Compressor be tripped-out for any reason, thereby preventing any unnecessary loss of pressure during the start-up when no oxygen is present in the system.  This bypass circuit will automatically drop out when the First Oxygen Block Valve, XV-1620 is opened.  A red light on the Auxiliary Panel will indicate cycle gas vent bypass.
Cycle gas can be vented manually by placing the selector switch HS-1564A in the vent position, or alternately by placing selector switch HS-1564C in the vent position. The Vent Valve XV-1564 can also be opened by the manual valve HV-1564C in the Instrument Air (IA) supply line to the solenoids. The white lights HYI-1564A and HYI-1564B on the Auxiliary Panel will indicate that the cycle gas vent opened by HS-1564A or the associated interlocks, and HS-1564C respectively.
When the Vent Valve XV-1564 is opened automatically by the interlock system, it will stay open for 90 seconds and then close again (Also see Section VIII Recycle Compressor Trips)
6.         Reset the Cycle Gas "Tracking Alarm"
     复位循环气“跟踪报警”

When the plant is initially being started, the cycle gas flow differential tracking alarm, FDALL-1611 will be satisfied by resetting HS-1611.
   循环气流量跟踪差报警在准备开车的时候必须先用HS-1611复位。

As explained in "Section IV - Tracking Alarm Description", this flow alarm, FDALL-1611, maintains a low alarm setpoint which tracks the actual flow.  The alarm setpoint increases as the flow increases, maintaining a predetermined ratio below the maximum flow which has been reached.
   如在“跟踪差报警描述中”所述,流量报警FDALL-1611维持一个跟踪实际流量的低报警设定点上。设定值随实际流量增大而增大,始终与流量维持一个预设的比例上,并低于流量值(即该比例值应小于1)。

The alarm setpoint may be lowered through the use of the reset push-button, HS-1611 which resets the alarm while the button is pressed.  When the push-button HS-1611 is released, the alarm setpoint is reset to a new lower setpoint.
在循环气流量减小的时候,通过复位按钮HS-1611来降低报警设定点。

7.         Bypass the Cycle Gas "Absolute" Low Flow Alarm
旁路循环气低流量报警
       Logic Diagram 5139-D-709B
When starting one reactor or both the reactors, it may be necessary to bypass the cycle gas low absolute flow alarms, FALL-1610A for one reactor in operation or FALL-1610B for two reactors in operation, with the bypass push-button, HS1610.
启动反应器之前(不论是一个反应器还是两个都启动),循环气低流量报警FALL-1610A(一个反应器操作)或FALL-1610B(两个反应器操作)须先通过旁路按钮HS-1610旁路。

Until the cycle gas low absolute flow alarm FALL-1610A/B is satisfied, the bypass in OMS interlock circuit will remain active.  However, once FALL-1610A/B is satisfied, the bypass is automatically cancelled.  A red light FAI-1610A on the Auxiliary Panel will indicate cycle gas Low-Low flow bypass.
旁路始终起作用,直到FALL-1610A/B消除,旁路将自动取消。附操台上红灯FAI-1610A将指示循环气低低流量报警的旁路状态。

8.         Ethylene Feed Valve
乙烯进料阀
     Logic Diagrams D-703, D-704
The Ethylene Feed Valve XV-1840 cannot be opened until Step 8 in the OMS start-up sequence is complete.  This will require that the controller FC-1838C output be set its minimum value.  Then in order to open the valve, the reset push-button HS-1840 must be pressed to energize solenoid XY-1840.  A green light on the Auxiliary Panel and on the DCS will indicate XY-1840 is energized.  
在OMS启动顺控的第8步完成后,乙烯进料阀门XV-1840可以被打开。这时,乙烯进料流量调节器FC-1838C的输出为0%(即流量调节阀FV-1838应处于关闭位置)。此时,触发复位按钮HS-1840使电磁阀XY-1840励磁,从而打开XV-1840。附操台上绿灯及DCS画面将显示XY-1840励磁。

The Ethylene B.L. Valve HV-1850 can be opened and closed by selector switch HS-1850 independent of any interlock.  A green light HYI-1850 on the Auxiliary Panel will indicate HY-1850 is energized.
乙烯界区阀HV-1850的开/关由操作员通过HS-1850手动操作,不受任何联锁影响。附操台上绿灯HYI-1850将显示HY-1850的励磁情况。

9.         Reset the Oxygen Differential Flow "Tracking" Alarm
复位氧气流量跟踪差报警
Before oxygen flow can be started, the oxygen differential flow tracking alarm FDALL-1563 must be in a satisfied condition.  This alarm is set at a predetermined ratio above the oxygen flow rate.  Whenever the oxygen flow rate is increased, HS-1563 will have to be held in until the oxygen flow has stabilized. The alarm setpoint will automatically track down as the oxygen flow is decreased.
在引入氧气之前,氧气流量跟踪差必须没有报警。该报警设定点与氧气流量是一个预设的固定的比例关系,且设定点值大于氧气流量。当氧气流量增大时,必须按着复位按钮HS-1563直至氧气流量稳定。当氧气流量减少时,该报警设定值会自动跟随流量减小。

At start-up with no oxygen flow, FDALL-1563 must be satisfied by pressing HS-1563. In addition, high "absolute" oxygen flow alarm FAHH-1619A (5139-D-16) will also be satisfied.  At start-up the oxygen flow controller FC-1619B must be on manual and output to a minimum value.
在开车的时候,氧气流量为0,所以必须使能HS-1563来消除FDALL-1563。另外,氧气流量高报警FAHH-1619A也必须是消除的。氧气流量调节器FC-1619B置于手动模式,且输出为最小阀位值。

10.         Check the Inlet Oxygen Analyzers
进口氧分析仪检查
     Logic Diagram D-708
The reactor inlet oxygen analyzer switch HS-1500 must be checked so that it is in the proper position.  Usually, this is the "NORMAL" position in which both Reactor Inlet Oxygen Analyzers AIT-1501 and AIT-1502 are online.   
检查进口氧气分析仪开关HS-1500是否在适当的位置。通常,是在“正常”位置,表示AIT-1501和AIT-1502都在线分析。
Each Reactor Inlet Oxygen Analyzer has separate alarms and shutdowns depending on whether methane or nitrogen is used for ballast gas.  HS-1518 allows switching between the two alarm settings. For initial start-up HS-1518 should be set to nitrogen ballast position.  AALL-1518A/B will not allow switching to methane ballast settings until the methane concentration in the cycle gas is high enough.  A green light HI-1518B on the Auxiliary Panel and a green light HI-1518C on the DCS will indicate that the methane ballast trip setpoints are active. A white light HI-1518A on the Auxiliary Panel will indicate that nitrogen ballast trip setpoints are active.   
置稳气(甲烷或氮气)不同的时候,反应器入口氧分仪的报警和联锁设定点是不一样的,设定值的变化是通过选择开关HS-1518来实现。在初始开车时,HS-1518必须置于氮气置稳的位置上,直到循环气中甲烷的含量高到一定值的时候才能够切换到甲烷置稳。附操台上的绿色灯HI-1518B及DCS操作画面上HI-1518C都用于指示甲烷置稳的氧气联锁设定值有效。附操台上白色灯HI-1518A则指示氮气置稳状态下的氧气联锁设定值有效。

High-High oxygen at anyone of the inlet analyzers as well as low sample flow or cell flow or failure of both analyzers will shutdown the OMS.  If either analyzer is to be put out of service for calibration, the HS-1500 selector switch must be set to bypass that analyzer. This will bypass the shutdown contact in OPS circuit.  When either analyzer is bypassed, a red "bypass" light is lit, both on the Auxiliary Panel UI-1501A/UI1502A and in the analyzer house UI-1501B/UI-1502B. The bypass interlock circuit is so arranged that when one of the analyzers is on "bypass", the other one in service cannot be bypassed.
任意一个入口氧分析仪的氧气含量高高报警、采样流量低、分析流量低及分析仪故障都会引起OMS停车。任一个氧分仪需要被维护校验,都必须用选择开关HS-1500来旁路该氧分仪。任一个氧分仪被旁路的时候,附操台上UI-1510A/UI-1520A和分析小屋中的红色指示灯UI-1501B/UI-1502B都将指示“旁路”。当其中一个分析仪被旁路时,另一个分析仪必须在线且不能旁路。

The process gas sample line and the cell of each analyzer are equipped with low flow alarm switches. Flow switch in the sample line is set for a flow rate (bypass plus cell flow) that would ensure minimum sample lag time, while the cell flow switch confirms flow through the analyzer.
采样管线和分析仪单元中都配有低流量开关。采样管线上的流量开关设置应能保证有足够的气体流量,而分析流量开关则是为了保证有气体流过分析仪。

11.         Check Outlet Oxygen Analyzer
Logic Diagram D-706
在开始氧气进料之前,反应器出口氧气分析仪AIT-1310和AIT-1410要在线运行:
A.低采样流量报警FAL-1310A/FAL-1410A消除
B.低分析流量报警FAL-1310B/FAL-1410B消除
C.氧含量高高报警AAHH-1310/AAHH-1410消除
D.分析仪故障报警UAL-1310/UAL-1410消除
一旦第一道氧气切断阀XV-1620打开,反应器出口氧分析仪AIT-1310/AIT-1410可以被旁路。
Before the oxygen feed can be started, the Reactor Outlet Oxygen Analyzers AIT-1310 and AIT-1410 must be in service. This will occur when the following conditions are met.
a. Low sample flow alarm FAL-1310A/FAL-1410A is satisfied.
b. Low cell flow alarm FAL-1310B/FAL-1410B is satisfied.
c. High-High oxygen concentration alarm AAHH-1310/AAHH-1410 is satisfied.
d. Analyzer failure alarm UAL-1310/UAL-1410 is satisfied.

Once the First Oxygen Block Valve XV-1620 is open, the Reactor Outlet Oxygen Analyzer AIT-1310/AIT-1410 can be bypassed.
12.         Open Oxygen Battery Limit Valve
打开氧气界区阀HV-1525
Logic Diagrams D-701 and D-704
为了消除差压联锁报警PDALL-1560和满足OMS启动允许条件(HV-1525的阀位开指示ZSO-1525A),必须打开氧气界区阀门HV-1525。若第一道氧气切断阀XV-1620是关闭的,则HV-1525可由HS-1525打开。一旦OMS启动,则禁止动作HS-1525;OMS联锁会自动关闭HV-1525。辅操台上的绿灯亮指示电磁阀HY-1525带电。
In order to satisfy the Low-Low differential pressure alarm PDALL-1560 and the OMS start-up permissive logic (by the open limit switch ZSO-1525A of HV-1525), it will be necessary to open the O2 B.L. Valve HV-1525. This valve can be opened by HS-1525 provided the first O2 block valve XV-1620 is closed. Once the OMS is started up, HS-1525 is inactivated, and an OMS trip will automatically close HV-1525. Green light on the Auxiliary Panel will indicate HY-1525 is energized.
13.         Ballast Methane and Nitrogen Valves
甲烷、氮气阀门
Logic Diagram D-704,D-712C
When ballast Methane or Nitrogen gas is being introduced via the Reclaim Compressor, the compressor must be running and the OMS is started before the reset push-button HS-3413A can be actuated to energize the solenoid FY-3413.  Green light on the Auxiliary Panel will indicate FY-3413 is energized.   
致稳气甲烷或氮气通过回收气体压缩机引入时,在电磁阀FY-3413通过HS-3413A复位带电之前,压缩机必须正常运行且OMS已启动。
In the alternate case, when ballast methane gas is directly introduced into the cycle gas, the Methane Valve XV-1636 cannot be opened until the OMS is started and Low pressure alarm PALL-1636 is cleared.  Then to open the valve, the controller FC-1635 must be set at minimum output and the reset push-button HS-1636 on the Auxiliary panel must be pressed to energize solenoid XY-1636.  A green light HYI-1636 on the Auxiliary Panel will indicate XY-1636 is energized.
另一种情况下,若致稳气甲烷直接被引入到循环气体中时,甲烷切断阀XV-1636要在OMS启动后才能打开,从而消除压力报警PALL-1636。流量调节器FC-1635必须设在最小输出值上,辅操台上的复位按钮HS-1636必须被触发使电磁阀XY-1636带电。

14.         Argon Vent Valve
氬气放空阀门
Logic Diagram D-704
The Argon Vent Valve, FV-1831, cannot be opened until Step 8 in the OMS start-up sequence is complete.  Then in order to open the valve, the reset push-button HS-1831 on the Auxiliary Panel must be pressed to energize solenoid FY-1831.  A shutdown of the OMS will close FV-1831.  A green light FYI-1831A on the Auxiliary Panel and a green light FYI-1831B on the DCS will indicate FY-1831 is energized.
氬气放空阀门FV-1831在OMS启动顺控完成第8步的时候才可以被打开。通过触发辅操台上的复位按钮HS-1831来使电磁阀FY-1831带电。OMS停车将会关闭FV-1831。

15.         Nitrogen to Inhibitor System Valve
氮气至抑制剂系统阀门
Logic Diagram 5139-D-704
The Nitrogen Valve PV-1942 cannot be opened until the OMS is started and until the Nitrogen supply Low-Low Pressure Alarm, PALL-1942, is satisfied. Then in order to open the valve, the reset push-button HS-1942 on the Auxiliary Panel must be pressed in order to energize solenoid PY-1942.  Green light PYI-1942 on the Auxiliary Panel will indicate PY-1942 is energized.
氮气阀门PV-1942在OMS启动且供气压力低低报警PALL-1942消除的情况下才可以打开。通过触发辅操台上的复位按钮HS-1942使电磁阀PY-1942带电。
B.Start-up of The Oxygen Mixing Station
氧混站的启动
Logic Diagrams D-701/2/3/4/5/10/11A/11B/11C
After completion of the preliminary operations, the start-up of the OMS can proceed if the valves are all in the positions required after either a planned or an emergency shutdown. Any valves which are not in proper position, for whatever reasons (maintenance, etc.), have to be set accordingly.  In addition, all required alarms have to be cleared. They are listed in Section VIII.
准备工作完成后,如果阀门在预定或紧急停车后正确的位置上,则OMS可以按程序启动。不论任何原因(如维护等),没在适当开度的阀门都必须调整。另外,所有相关的报警都必须消除。这些在VIII部分有列表。
These valve positions are:
       阀门位置如下:
       一级氧气切断阀XV-1620       关闭

Red and green lights will indicate the above valve positions on the DCS graphic display.
当所有氧气进料允许条件都满足,且辅操台上的OMS推-拉式停止按钮HS-1601B在“运行”位置上时,辅操台上将有绿灯显示,指示条件具备。
When all the oxygen permissive circuits are satisfied and the OMS shutdown push-pull switch HS-1601B on the Auxiliary Panel is in the RUN position, a green light will come on the Auxiliary Panel.
触发辅操台上主继电器复位按钮HS-1601C,此时“Ready to Start”绿灯亮,只是所有关键阀门阀位都已正确。
      触发辅操台上“启动”按钮HS-1601A,OMS停止灯将灭掉。
      
      顺序控制I 可以开始执行。
Press the Master Control Relay reset push-button HS-1601C on the Auxiliary Panel.  The “Ready to Start” light will come on the Auxiliary Panel indicating that the critical valves in the OMS are in the correct position for start-up.
Press the Start Push-button HS-1601A on the Auxiliary Panel.  The OMS shutdown light on the Auxiliary Panel will go off.
Sequence I can now begin.
Sequence I
STEP INDICATOR SHOWS "00"
Purge Spargers and Test 2nd Nitrogen Bottle SP-1602 for Leaks
步骤显示“00”
吹扫分布器并对第二个氮气瓶SP-1602测漏
打开HV-1625(大分布器第二道切断阀),HV-1627(小分布器第二道切断阀),XV-1630(SP-1602氮气补给阀)。
当HV-1625和HV-1627打开后,氮气流量将消除低流量报警FAL-1632和FAL-1633,且有流量指示FI-1632和FI-1633。
XV-1630打开后,SP-1602与氮气供气压力相等,如果SP-1602及HV-1624、HV-1626、XV-1623间的管道都没有泄露的话,PALL-1631将保持正常。

This will open the Second Block Valve of the Large Sparger HV-1625, the Second Block Valve of the Small Sparger HV-1627 and the nitrogen to the Second Nitrogen Bottle SP-1602, XV-1630. When the second block valves on the spargers are open, nitrogen flow will clear the flow alarms FAL-1632 and FAL-1633. Resulting flows are shown on flow indicators, FI-1632 and FI-1633.
Simultaneously, the opening of nitrogen valve XV-1630 will equalize the pressure in SP-1602 with the nitrogen header and thereby PALL-1631 will be cleared.  If there is no excessive leak in SP-1602 and the downstream piping blocked in by the First Sparger Blocks HV-1624 and HV-1626 and the Third Oxygen Block XV-1623, PALL-1631 will remain cleared.
STEP INDICATOR SHOWS "01"
Open the First Sparger Block Valves for a Five Second Purge of Both Spargers via the 2nd Nitrogen Bottle, SP-1602
步骤显示“01”
FAL-1632,FAL-1633和PALL-1631都正常时,HV-1626(小分布器第一道切断阀),HV-1624(大分布器第一道切断阀)将被打开。
此时,由于SP-1602的压力与循环气压力相等,将会产生压力低低报警PALL-1631。

When the Flow Alarms FAL-1632 and FAL-1633 and the pressure alarm PALL-1631 are cleared, the First Block of the Small Sparger HV-1626 and the First Block Valve of the Large Sparger HV-1624 will open.
PALL-1631 will alarm since the pressure in SP-1602 will equalize with the cycle gas pressure.
Close Small and Large Spargers Second Block Valves Check the Pressure Alarms of the Large and Small Spargers
吹扫5s后,关闭HV-1625,HV-1627,切断阀前压力上升至氮气供气压力,低压力报警PALL-1631、PALL-1632和PAL-1633消除,将产生低流量报警FAL-1633和FAL-1632。由于停车逻辑中PAL-1632超驰FAL-1632,PAL-1633超驰FAL-1633,所以启动程序将继续执行。
After a five second purge, the Second Block Valve of the Large Sparger HV-1625 and Second Block Valve of the Small Sparger HV-1627 will close.  The pressure upstream of the blocks will rise to the nitrogen supply pressure.  This will clear alarms PALL-1631, PAL-1632, and PAL-1633. FAL-1633 and FAL-1632 will alarm, but start-up will continue since PAL-1632 will override FAL-1632 and PAL-1633 will override FAL-1633 in the shutdown circuit.

The Ethylene Feed Valve, XV-1840 can be opened by pressing its reset push-button HS-1840 on the Auxiliary Panel.
The Ballast Methane Feed Valve XV-1636 and Ballast Methane/Nitrogen Feed Valve FV-3413 can be activated by pressing their reset push-button HS-1636 and HS-3413A, so they can be opened and/or operated from their respective controllers.  The output of controller FC-1635 must be first set to 0% (less than 4 mADC) before XV-1636 can be reset and opened.
The Argon Vent Valve, FV-1831, can be activated by pressing its reset push-button HS-1831, so it can be operated from its controller.
Nitrogen to the Inhibitor System Valve PV-1942 can be opened by pressing its reset push-button, HS-1942 on the Auxiliary Panel.
Inhibitor Feed Valves XV-1512 and XV-1522 are ready to be opened by pressing the reset push-button HS-1512 and HS-1522, respectively.
Note: The output of FC-1838C must be less than 0% (4 mADC) to reset and operate XV-1840, XV-1512, XV-1522 and FV-1831.

Establish Nitrogen Purge Through Small Sparger
Set the Oxygen Flow Controller FC-1619B output to less than 4 mADC.  After Oxygen Flow Valve FV-1619 is closed, the Small Sparger operation can be started by push-button HS-1602 which will open the First Block Valve of the Small Sparger HV-1626, and the Second Block Valve of the Small Sparger HV-1627.  Nitrogen will flow to the Small Sparger via XV-1633 and FAL-1633 will clear and PAL-1633 will alarm.
Open First and Third Oxygen Block and then Start Oxygen Flow
When the Flow Alarm FAL-1633 is cleared, the First Oxygen Block Valve XV-1620 and the Third Oxygen Block Valve XV-1623 will open.

步骤显示“09”
按照操作规范,氧气流量调节阀FV-1619可按要求打开一定开度,在反应器进料循环气中建立期望的氧含量。
增加氧气进料量,直到分布器压力差压报警PDALL-1628消除。差压报警消除10s后,关闭XV-1633。此时低流量报警FAL-1633产生,差压报警PDALL-1628消除,OMS操作继续。
By following the plant operating guidelines, the Oxygen Flow Valve FV-1619 can be opened as required to start the reaction and to establish the desired oxygen concentration in the cycle gas feed to the Reactor.
Increase the feed of oxygen until the Sparger differential pressure alarm PDALL-1628 is cleared. This will close the nitrogen to Small Sparger Valve XV-1633 after a ten second delay.  The flow alarm FAL-1633 will activate but the differential pressure alarm PDALL-1628, now cleared, will allow the OMS operation to continue.
STEP INDICATOR SHOWS "10"
步骤显示“10”
此时,小分布器处于正常操作工况下,氧气流量增加,小分布器差压指示值PDI-1628将会超量,这时分布器差压由较大量程的PDI-1627显示监测。
The Small Sparger is now under normal operation.  As the oxygen flow is increased with the Small Sparger in operation the sparger differential pressure, PDI-1628 will go out-of range (range 0-1,250 mm H2O), The sparger differential pressure can then be monitored by the higher range differential pressure indicator PDI-1627.   
Change to Two Sparger Operation
切换为两分布器操作模式
当分布器差压PDI-1627显示2-2.2kg/cm2g的时候,打开大分布器。氧气流量调节器FC-1619B置于手动模式,慢慢减少调节器输出,这样当大分布器投用时氧气流量才不会增加过快。投用大分布器的确切的PDI-1627的差压值以及氧气调节阀输出减少的量,将在OMS氮气试运行阶段确定。
触发辅操台上按钮HS-1603,打开XV-1633,使氮气进入小分布器。大分布器二级切断阀HV-1625打开,氮气通过XV-1633进入大分布器。氮气流将消除小流量报警FAL-1632和低压力报警PAL-1632。


When the sparger differential pressure PDI-1627 reaches about 2 – 2.2 kg/cm2g the Large Sparger should be started.  Put the oxygen flow controller, FC-1619B, on manual mode and slightly reduce the output so that after the Large Sparger is put in operation the oxygen flow will not increase appreciably.  The exact value of PDI-1627 that is required for starting the Large Sparger and the output reduction of the oxygen control valve will be determined during the OMS test run with nitrogen.
Press button HS-1603 on the Auxiliary Panel. This will open the nitrogen to the Small Sparger Valve, XV-1633, again.  The Second Block Valve of the Large Sparger HV-1625 will open and nitrogen will flow to the Large Sparger via XV-1633.  The nitrogen flow will clear FAL-1632 and PAL-1632 will alarm.
STEP INDICATOR SHOWS "11"
步骤显示“11”
打开大分布器一级切断阀HV-1624,让氧气通过。
在打开大分布器前快速建立氧气流量到相同的量上。

This will open the First Block Valve of the Large Sparger, HV-1624, allowing oxygen to flow through both spargers.
Quickly reestablish oxygen flow to the same value prior to starting the Large Sparger.
STEP INDICATOR SHOWS "12"
步骤显示“12”
HV-1624打开后,延时30s,关闭XV-1633和XV-1632,保持关闭。分布器差压降低到500 mmH2O。必须建立流量使差压保持在380 mmH2O之上,否则OMS将连锁停车。

When the First Block Valve of the Large Sparger HV-1624, opens, a time delay starts.  After thirty seconds, Nitrogen to the Small Sparger Valve, XV-1633 and nitrogen to the Large Sparger Valve, XV-1632, will close and remain closed.  The sparger differential pressure will decrease to about 500 mm H2O with both spargers in operation.  Flow must be stabilized to maintain the differential pressure above 380 mm H2O at all times from this point onwards or the OMS will shutdown.
STEP INDICATOR SHOWS "13"
步骤显示“13”
顺控完成了,步骤显示“13”,表示OMS正常运行。
Sequence II is now completed and the step indicator will show "13" indicating that the OMS is in normal operation.
在顺控执行过程中,任何时候跳到暂停,步骤显示保持在当前步骤。一旦操作员排除故障后,顺控将继续进行下去。
If at any time during the sequences the operation comes to a halt, the step indicator light will remain on the current step, indicating where in the sequence this occurred.  Once the problem is corrected by an operator, the sequence can resume further operation.
