摘　　要：大庆油田有限责任公司天然气分公司的油田气浅冷轻烃回收装置中使用的轻烃凝液泵基本采用多级低温泵、屏蔽电泵。随着生产运行工况的不断变化,已经不能满足轻烃泵的运行要求。由于流量大、扬程小、间歇运行困难,原有设计的轻烃泵存在气阻、汽蚀等问题,逐步退出运行。为了满足生产需求,经过分析论证,在轻烃生产装置中首次采用了滑片泵。运行实践表明:其有效地解决了工艺生产中存在的问题,提高了系统运行压力,解决了轻烃储罐"降压收烃"操作,减少了轻烃蒸发损耗,实现了增产轻烃、节能减排的目的。Basically,multi-stage centrifugal pumps are popular choice for light-hydrocarbon condensate in gas shallow cooling facilities.The pumps were selected according high flows,low head and intermittent operating application.With the changing of production operation condition,light-hydrocarbon condensate pumps with some problems,such as air resistance,cavitation gradually withdraws,have not been able to meet the operating requirements.Based on analysis of the argument,vane-pump was first applied in gas shallow cooling facilities to meet the operating requirements.Through running practice,the optimized pump selection effectively increased operating pressure,solved the issues of light-hydrocarbon tank"step-down hydrocarbon"operation,reduced the evaporation loss of lighter hydrocarbon,and improved output.The purposes of energy saving and emission deduction have achieved.
