摘要：作者：趙志偉; 杜塏 關(guān)鍵詞：暖通空調(diào)論文,油氣回收,復(fù)疊循環(huán) 【中文摘要】 汽油等油品在儲(chǔ)運(yùn)過程中會(huì)有部分輕烴組分揮發(fā)進(jìn)入大氣,與空氣混合成為油氣。這部分油氣在儲(chǔ)運(yùn)過程中難免會(huì)產(chǎn)生環(huán)境污染、能源浪費(fèi)等問題,利用復(fù)疊制冷循環(huán)制取低溫來冷凝油氣中的輕烴組分,實(shí)現(xiàn)油氣回收、節(jié)能減排已成為業(yè)內(nèi)研究的熱點(diǎn)課題之一。冷凝法油氣回收裝置的能耗是研究者普遍關(guān)心的問題,本文提出了一種冷凝法油氣回收系統(tǒng),計(jì)算了溫度變化時(shí)冷凝負(fù)荷的變化,從理論上分析了機(jī)組能耗隨環(huán)境溫度變化的規(guī)律。并指出了降低機(jī)組能耗的關(guān)鍵。 【英文摘要】 Light hydrocarbon components of petroleum products such as gasoline evaporate into atmosphere in the process of stockpiling and transportation, which mix with air as components of refueling gas. 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(guān)鍵詞】 油氣回收; 復(fù)疊循環(huán); 雙級(jí)壓縮; 能耗; 油氣儲(chǔ)運(yùn)【英文關(guān)鍵詞】 refueling gas recovery; cascade cycle; two stage compression; power consumption; refueling gas storage and transportation
