摘　　要：新疆油田天然气压缩机以天然气为燃料压缩天然气增压外输,当机组排烟温度为370~400℃时,烟气余热未经回收利用,使排烟损失较大;同时缸体冷却水余热通过风冷器直接排放,造成压缩机组综合热能利用率低。结合处理站用热情况,对余热回收工艺技术进行了分析比较,提出了有针对性的余热回收解决方案。采用余热锅炉回收高温烟气余热,产生的蒸汽用于原油掺热;采用烟气冷凝器回收低温烟气余热用来加热锅炉补水;采用水-水换热器替代风冷器回收缸体冷却水余热,最大限度地回收压缩机余热;并根据余热利用项目的运行效果,做出经济技术分析。The natural gas compressor in Xinjiang Oilfield uses natural gas as fuel for external transport natural gas compressing and boosting.On 370~400 ℃,smoke of the unit is without the use of waste heat,the smoke loss is great,besides the cylinder cooling heat discharges directly through the air cooler,the comprehensive heat energy utilization efficiency of the compressor unit is low. Based on the actual situation of processing station, using waste heat boiler to recover the waste heat of high temperature flue gas to produce steam and then heat the crude oil,using flue gas condenser to recover low temperature flue gas waste heat to heat boiler water, at the same time, using water-water heat exchanger instead of the air cooler to recover the waste heat of the cylinder cooling water, and the waste heat of compressor could be recovered to the utmost. According to the operating effect of waste heat utilization project, economic technical analysis could be made.
