【摘要】：在油品生產(chǎn)、儲運和銷售過程中,油氣極易揮發(fā)到大氣中,造成油品的蒸發(fā)損耗,不僅造成資源浪費,還帶來環(huán)境危害和安全隱患。油氣回收有利于環(huán)保、安全和節(jié)約資源,是一項有經(jīng)濟效益的環(huán)�；顒�。本文以加油站蒸發(fā)損耗為背景,借助Aspen Plus軟件及實驗研究,完成了以下工作：利用Aspen Plus軟件對冷凝法回收油氣過程進行了模擬與優(yōu)化。靈敏度分析了冷凝溫度、進料狀態(tài)、進料組成、操作壓力對油氣回收過程的影響。研究發(fā)現(xiàn)：油氣回收率隨著冷凝溫度的降低而升高；進料流量、溫度、壓力變化對油氣回收率不影響,但是隨著進料流量、溫度和壓力的增加,能耗隨之增加。同一冷凝溫度下,組分含碳原子數(shù)越多,油氣回收率越高。吸附法回收油氣實驗研究對油氣回收過程工藝參數(shù)進行了優(yōu)化。以油氣的回收率為目標函數(shù),確定了吸附效果較優(yōu)的吸附劑為3≠活性炭吸附劑。完成了吸附-冷凝法二級油氣回收技術(shù)過程工藝集成研究。在冷凝法回收油氣過程流程模擬的基礎(chǔ)上,以活性碳作為吸附劑,對吸附-冷凝法二級油氣回收過程工藝參數(shù)進行了優(yōu)化；最后,對集成過程進行了技術(shù)經(jīng)濟分析,研究表明,吸附-冷凝法回收油氣具有較好的工程經(jīng)濟性。
[Abstract]:In the process of production, storage, transportation and sale of oil products, oil and gas are easily volatilized into the atmosphere, resulting in evaporation loss of oil products, which not only causes waste of resources, but also brings environmental hazards and hidden dangers to safety. Oil and gas recovery is beneficial to environmental protection, safety and conservation of resources. In this paper, based on the evaporation loss of gas station, with the help of Aspen Plus software and experimental research, the following work has been accomplished: the process of oil and gas recovery by condensing method has been simulated and optimized by using Aspen Plus software. The effects of condensing temperature, feed state, feed composition and operating pressure on oil and gas recovery process were analyzed. It is found that the recovery rate of oil and gas increases with the decrease of condensing temperature, but the energy consumption increases with the increase of feed flow rate, temperature and pressure, while the change of feed flow rate, temperature and pressure does not affect the recovery rate of oil and gas. At the same condensation temperature, the higher the number of carbon atoms in the components, the higher the recovery of oil and gas. The process parameters of oil and gas recovery were optimized by adsorption method. With the recovery rate of oil and gas as the objective function, the best adsorbent was determined as 3 鈮，
