Abstract： In order to solve the practical problems of oil and gas recovery in oil depots， the characteristics of common oil and gas recovery technology methods were compared， and a “silica-activated carbon” adsorption method for oil and gas recovery system was designed. Combined with actual situation of Lu'an oil depot and filling station in Sinochem petroleum Anhui Co.， Ltd.，the application of the oil and gas recovery system was studied. The results showed that the “silica-activated carbon” adsorption method for oil and gas recovery had the advantages of simple operation and obvious economic benefits， and the priority of each index in the selection of adsorbent was as follows： adsorption selectivity> pore volume> mass transfer dynamics> cost > renewability and compatibility. The research results can provide theoretical support for the design of oil and gas recovery technology solutions and the choice of adsorbents.

Key words： Comprehensive utilization of energy; Oil and gas recovery; "silica gel-activated carbon" adsorption method; Adsorbent selection

隨着我国国民经济的不断发展，石油产品的生产和消费呈现井喷式增长形式，石油行业迎来了迅猛发展的阶段。然而由于石油产品加工和储运过程中产生大量的油气，一方面造成了能源的大量浪费，另一方面，油气中含有多种气相烃类有毒有害气体，易造成中毒事故。同时因油气具有较为活跃的化学活性，当浓度达到一定限度后，极易造成火灾爆炸事故，据不完全统计，造成汽油及其化学制品火灾爆炸事故的主要原因是产品储运过程中的会发产生的可燃气体。据国际统计局统计数据显示，2018年我国原油加工量达6.0357亿t，原油储运过程挥发损失约为3‰^[1]，油气损失量约为10亿m?，造成大量的经济损失和环境污染。因此，加强油库油气回收工作势在必行。……
