【摘要】：在油品生产、储运和销售过程中,油气极易挥发到大气中,造成油品的蒸发损耗,不仅造成资源浪费,还带来环境危害和安全隐患。油气回收有利于环保、安全和节约资源,是一项有经济效益的环保活动。本文以加油站蒸发损耗为背景,借助Aspen Plus软件及实验研究,完成了以下工作：利用Aspen Plus软件对冷凝法回收油气过程进行了模拟与优化。灵敏度分析了冷凝温度、进料状态、进料组成、操作压力对油气回收过程的影响。研究发现：油气回收率随着冷凝温度的降低而升高；进料流量、温度、压力变化对油气回收率不影响,但是随着进料流量、温度和压力的增加,能耗随之增加。同一冷凝温度下,组分含碳原子数越多,油气回收率越高。吸附法回收油气实验研究对油气回收过程工艺参数进行了优化。以油气的回收率为目标函数,确定了吸附效果较优的吸附剂为3≠活性炭吸附剂。完成了吸附-冷凝法二级油气回收技术过程工艺集成研究。在冷凝法回收油气过程流程模拟的基础上,以活性碳作为吸附剂,对吸附-冷凝法二级油气回收过程工艺参数进行了优化；最后,对集成过程进行了技术经济分析,研究表明,吸附-冷凝法回收油气具有较好的工程经济性。
[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，
