COMPRESSOR PLANTThe compressor unit is meant to be continuously running throughout the year.This chapter describes the three interacting systems of the compressor plant: The gas, the lube oil andthe cooling water system.2. 压缩机厂压缩机组是一年四季不断运行。本章介绍的压缩机厂的三个交互系统：气体，润滑油和冷却水系统。2.1 General Description and Gas SystemThe heart of the compressor unit is the five-stage labyrinth-piston compressor, type 5LP250-5A_1. It is driven by an electric motor.The process gas is cooled after each compression stage. Before leaving the compressor unit, the process gas is filtered since abnormally high temperature combined with high pressure may produce undesirable carbon-dust and C02.Pulsation and vibration reducing measures used are pulsation dampers at the inlet and outlet of every compression stage, gas piping layout and strategically placed orifices.By means of safety pressure valves, every compression stage is protected against overpressure.2.1一般说明和天然气系统压缩机机组的心脏，是五个阶段的迷宫式活塞式压缩机，类型5LP2505A_1。它是由一个电动机驱动。工艺气体冷却后，每个压缩阶段。临走压缩机，工艺气体过滤以来异常高温高压相结合，可能会产生不良碳灰尘和二氧化碳。脉动和减振措施，使用脉动阻尼器在每个压缩阶段，天然气管道的布局和战略放在窍的进风口和电源插座。通过安全压力阀，每个压缩阶段是对超压保护。Gas StreamsThe compressor unit Y021701 is designed to densify carbon monoxide to 3.95 MPa a. The compressor unit receives the CO from the cold box at three different levels:气体流目的是致密3.95 MPa A.一氧化碳压缩机单位Y021701压缩机单元接收从三个不同层面的冷箱的CO： . from the main suction line L01, at 0.15 MPa a . from the side stream line L03, at 0.55 MPa a . from the side stream line L04, at l.05 MPa aEach of the side streams roughly doubles the flow of the main stream.For maintenance, running-in of the labyrinth-type pistons and for start-up of the plant, nitrogen is required. In these cases, nitrogen replaces the process gas. The main suction line is therefore connected to a nitrogen supply line and a separate nitrogen supply line to the crankcase of the compressor. The client has to make sure that there is enough nitrogen available from the suction lines, so that the compressor is not facing a vacuum during start-up with nitrogen. For nitrogen requirement and start-up case, see also Utility Consumption List and Compressor Performance Summary.每个侧流，大约干流流量增加一倍。维护，迷宫式活塞和工厂启动运行，氮是必需的。在这种情况下，氮取代的过程气体。因此，主要吸线连接到一个氮的供应线和一个单独的氮压缩机曲轴箱的电源线。客户端，以确保有足够的氮可自吸线，使压缩机面对的不是一个在启动时用氮气真空。启动的情况下需要氮气，也见实用消费清单和压缩机性能摘要。Capacity ControlThe capacity of the compressor unit has to be adapted to the gas streams coming from the cold box.The capacity is adjusted by the means of three by-passes, each equipped with an automatic valve. All three by-passes combined together work as a by-pass overall. For a more detailed description, see chapter 6 Continuous Operation.容量控制压缩机的能力，以适应从冷箱的气流。调整能力是由三个通行证，每个配有自动阀门的手段。所有这三个传递结合在一起工作作为通过整体。对于更详细的说明，请参阅第6章连续运行。Shut DownIn case of compressor shut-down, at first, all the automated valves take their fail safe position: The by-pass valves close and the discharge vent valve (PV-0217604) opens.In case of normal shut-down, the by-pass valves will re-open in a cascade when their upstream pressure is lower then the downstream pressure in order to vent the plant through the discharge vent valve. Details are given in section 7.1 Normal Stop.In case of emergency shut-down, the by-pass valves and the vent valve will remain in their fail safe position. If not released manually, the gas trapped by the by-pass valves will partly flow through the piston rod packings to the crankcase and partly through the compressor cylinders to the vent valve. The gas flowing to the compressor crankcase is lead to the tail gas through the pressure control valve PCV-0217608.关机在压缩机的情况下关机首先，所有的自动阀门故障安全位置：旁通阀关闭和打开放电放空阀（PV-0217604）。在正常关机的情况下，旁通阀会在级联重新开放时，其上游压力低于下游的压力，以发泄通过放电排气阀厂。详情载于第7.1节正常停止。在紧急情况下关闭，旁通阀和排气阀将留在他们失败的安全位置。如果没有手动释放，由旁通阀的气体被困将部分活塞杆填料流过曲轴箱，并通过压缩机气缸部分的排气阀。流向压缩机曲轴箱的气体是导致尾气通过压力控制阀PCV-0217608。2.2 Gas Connections to CrankcaseDuring operation of the compressor, the crankcase does not need purging and so, the hand valves HV-10 and 11, downstream L12, are closed ref. to PID Gas System. There is a dedicated section ref. to.3.3 describing the purging of the compressor unit.The other side of the compressor crankcase, L13, is connected to the tail gas. During normal operation,there is no gas flow through L13. But in the following cases, there is gas flow:. through HV-13, during purging of crankcase. when the pressure in the crankcase rises above 0.15 MPa g (e.g. caused by piston rod packing failure or if the pressure on the suction side of the compressor rises above 0.15 MPa g), the self-acting valve PCV-0217608 will open releasing the pressure to the tail gas. Only in case that PCV-0217608 fails, the safety valve SV-021714 will act.2.2气相连接到曲轴箱曲轴箱压缩机的运行过程中，并不需要清洗和使，手阀HV- 10和11，下游L12，关闭参考。 PID气体系统。有专门的一节参考。 to.3.3描述清除压缩机。压缩机曲轴箱的另一侧，L13号，是连接尾气。在正常操作过程中，有没有气流量通过L13号。但在下列情况下，有气流量：。通过HV- 13，在曲轴箱的清洗。当曲轴箱的压力上升超过0.15兆帕克（如活塞杆填料故障或压缩机的吸入侧的压力上升0.15兆帕克以上，造成），自作用阀PCV-0217608将打开释放压力尾气。只有在PCV-0217608失败的情况下，将充当安全阀SV-021714。2.3 Lube Oil SystemThe well-functioning of the lube oil system is crucial for trouble-free compressor operation.The oil system consists of the following main parts ref. to PID Oil System:2.3润滑油系统润滑油系统的良好运作是无故障压缩机运行的关键。油系统由以下主要部分参考。 PID油系统： . oil sump, located in the compressor crank case, from where the oil flows to the . electric oil heater, heating only, if the oil temperature (measured by TE-0217658) is too low. .

A pressure control valve (PDCV) maintains the oil pressure at a constant differential pressure between the oil sump and the discharge side of the oil pumps. The excess oil flows back to the oil sump. . Parallel to the PDCV, there is a pressure safety valve. . the oil cooler evacuates the heat from the oil system during operation of the compressor. . Before re-entering the compressor, the oil goes through a filter. In the compressor, the oil lubricates the mechanical parts, also withdrawing heat. . The oil cycle is completed and the oil flows back into the oil sump. The oil system is equipped with a bladder-type oil accumulator to ensure oil flow when duty is switched from one pump to the other.。油底壳，位于压缩机曲轴箱，油从那里流向 。电油加热器，加热，如果油的温度（TE-0217658）太低。 。油是由两个平行油泵之一。 。压力控制阀（PDCV）保持在一个恒定的压差之间的油槽和油泵的排出端的油压。多余的油流回油底壳。 。平行的PDCV，是有压力安全阀。 。机油冷却器疏散压缩机的运行过程中的热油系统。 。在重新进入压缩机，油经过过滤器。 。 在压缩机，油润滑的机械部件，也撤回热。 。完成油循环和油流回到油底壳。 。 配备膀胱型油蓄能器油系统，以确保油流时的职责是由一台泵切换到其它。Oil Pumps P021761ABOne oil pump has to be running at least 2() minutes before compressor start, during the entire compressor operation and 5() minutes after normal compressor stop.One of the two oil pumps in parallel works as master, the other as slave. If in automatic mode, master and slave are toggled after each oil pump start. Normally, only the master oil pump is working.石油泵P021761AB一个油泵运行（）正常压缩机停止后至少压缩机前启动2（）分钟，在整个压缩机的运行和压缩机正常停止5（）分钟后。其中一个作为主站，其他为从属的并行工程的两个油泵。如果在自动模式下，主站和从站，每个油泵启动后切换。通常情况下，只有主油泵工作。Manual Start / Stop of the oil pump: .
