The low temperature condensation method of refueling gas recovery, which utilizes cascade cycle technique, is becoming the research focus. The power consumption of the condensation refueling gas recovery equipment is concerned by researchers and manufacturers. A condensation refueling gas recovery system was presented in this paper. The variation of power consumption and heat load of condenser with the change of ambient air temperature was calculated and the variation relationship between them was analyzed theoretically. The crux of energy consumption reduction was indicated. 【中文关键词】 油气回收; 复叠循环; 双级压缩; 能耗; 油气储运【英文关键词】 refueling gas recovery; cascade cycle; two stage compression; power consumption; refueling gas storage and transportation
