北Ⅰ-1原油稳定装置油吸收技术试验

Application of the skid-mounted oil absorption technology in Bei l-1 crude oil stabilization equipment

大庆油田北I-1原油稳定装置首次采用常温油吸收技术,不但能解决北I-1天然气深冷装置负荷低和分子筛吸烃的问题,而且可避免原油稳定装置与天然气深冷装置检修期相互制约的问题。现场实施后,不凝气轻烃收率达到16.3 t/104m3,关键组分C2收率达到85%,天然气深冷装置年可增加湿气处理量990×104m3,减少分子筛吸烃损失800 t/a、轻烃2780 t/a。降低了丙烷制冷机耗电量,原油稳定和深冷装置合计年节电量为60×104k Wh。

The skid-mounted oil absorption technology for stabilization equipment was used firstly in Daqing oilfield.It reduced the restrictions of the area of site and the investment on technology applications.Some problems can be solved by using the skid-mounted oil absorption technology in Bei I-1 crude oil stabilization equipment,such as the low load state and the molecular sieve absorption hydrocarbon in natural gas cryogenic treating unit.The interaction between Bei 1-1 crude oil stabilization equipment and Bei I-1 cryogenic treating unit for natural gas can be avoided in maintenance period.After implements,the light hydrocarbon yield from non-condensable gas is 16.3 t/10~4 m^3,the recovery rate of C_2 is 85%,990×10~4 m^3/a of treated wet gas can be increased in natural gas cryogenic treating unit,800 t/a of hydrocarbon and 2780 t/a of light hydrocarbon can be increased by using this technology.60×10~4 kWh of power for propane refrigerator,crude oil stabilization equipment and cryogenic unit can be saved per year.
