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. 【中文關鍵詞】 油氣回收; 復疊循環(huán); 雙級壓縮; 能耗; 油氣儲運【英文關鍵詞】 refueling gas recovery; cascade cycle; two stage compression; power consumption; refueling gas storage and transportation
