摘　　要：我国油气站点,尤其是无网电的边远站点,为消除伴生气的排放,实现伴生气的利用,对于天然气发电的使用愈发广泛。根据测试发电燃气只有33%的热量用来发电,约有42%的热量通过高温烟气排空,燃气发电机产生的高温烟气和缸套水如何高效回收利用,满足节能、安全、环保的要求已成为相关领域关注的重点。华北油田分公司第四采油厂永清气处理站有2台1 200 kW燃气发电机组,发电功率约为800~900 kW。该站由燃气蒸汽锅炉提供热能满足生产和生活用热,动力采用济柴2台1 200 kW天然气发电机并网发电,发电机烟气和缸套水的热量未回收,热损失大。烟气和缸套水余热回收工艺和镍基钎焊热管余热锅炉在永清站的现场应用,可将燃气热效率提高到70%,替代或降低燃气锅炉的负荷。结果表明燃气发电机烟气和缸套水的余热回收综合利用,2022年1季度减少燃气使用30×10~4m~3,创效约60万元。取得了良好的经济效益。In order to eliminate the emissions of associated gas and realize the utilization of associated gas, gas power is increasingly widely used in oil and gas stations, especially remote stations without grid power. According to the test,only 33% of the heat is used to generate electricity, and about 42%of the heat is drained through the high-temperature flue gas. How to efficiently recycle the high-temperature flue gas and cylinder liner water generated by the gas generator to meet the requirements of energy-saving, safety and environmental protection has become the focus of concern in related fields.Even more to the point,the Yongqing gas treatment station of the fourth oil production plant of Huabei oilfield company has two 1 200 kW gas generating sets with a power of about 800~900 kW. The station is powered by two 1 200 kW natural gas generators connected to the grid. The heat of the generator flue gas and cylinder liner water is not recovered,resulting in large heat loss. The field application of waste heat recovery technology of flue gas and cylinder liner water and waste heat boiler of nickel base brazing heat pipe in Yongqing station can increase the gas thermal efficiency to 70%, which can replace or reduce the load of gas boiler. Most importantly,the results show that the waste heat recovery and comprehensive utilization of gas generator flue gas and cylinder liner water can reduce 300, 000 cubic meters of gas in the first quarter of 2022, creating an effect of about 600,000 yuan.
