摘　　要：往复式压缩机的电耗在炼油能耗中占有较大比例,降低往复式压缩机的电耗是降低炼油能耗的主要手段之一。HydroCOM系统是一种适用于往复式压缩机的高效气量调节技术,可以实现对压缩机出口压力的自动控制,实现20%～100%负荷的自动无级调节。介绍了其基本原理、系统组成和控制。2006年至2011年,齐鲁炼厂在临氢装置增设了6套HydroCOM无级调量系统,6台压缩机的入口压力最低为0.23MPa,最高为2.1MPa,出口压力最低为2.5MPa,最高为19.3MPa,压缩机气缸的压比最低为1.7,最高为3.5;HydroCOM系统投用率平均达到90.5%,节电效果明显。在HydroCOM无级调量系统应用过程中,成功解决了气阀存在的问题,进一步优化了HydroCOM系统的控制方案;针对压缩机最低负荷设定偏低、压缩机停运时启用同步按钮易造成气阀超温的问题,采取相应措施,确保了HydroCOM系统的正常运行。工业应用表明,该技术可最大限度地实现压缩机的节能,且操作简单,便于维护。The reciprocating compressor＇s power consumption accounts for a large proportion of the energy consumption by a refinery.Reducing the power consumption of the reciprocating compressor is one of the main means of reducing refineries＇ energy consumption.The HydroCOM system is an efficient air flow regulat- ing technology suitable for reciprocating compressors and can be used to control the pressure at the outlet of the compressors automatically,achieving an automatic infinitely variable control of 20%-100% load.This article describes the system＇s working principle,components and operation.From 2006 to 2010,Sinopec Qilu Compa- ny＇s refinery added six HydroCOM systems to its units in direct contact with hydrogen.The minimum inlet pressure of six compressors is 0.23MPa and the maximum pressure is 2.1MPa.The minimum outlet pressure is 2.5MPa and the maximum is 19.3MPa.The minimum cylinder compression ratio of the compressors is 1.7 and the maximum ratio is 3.5.An average 90.5% of the HydroCOM systems have been put into use and a large amount of electricity has been saved.In applying the HydroCOM system,technicians addressed the prob- lems with air valves and optimized the control for the HydroCOM system.To the problems that the minimum compressor load was set too low and that enabling the sync button when the compressors stop often causes overheat of air valves ,they also came up with solutions to ensure the normal operation of the HydroCOM system.Industrial application shows that this technology can maximize the energy savings on compressors and is easy to use and maintain.
