The invention discloses an oil tank truck organic matter permselective membrane method cleaning system and an operation process. A nitrogen conveying pipeline is connected to an oil tank truck througha compressor and a gas heater; an outlet of the tank truck is connected to a condenser; an outlet of the condenser is simultaneously connected to a liquid storage tank and an organic matter permselective membrane group; and condensate obtained by the condenser is collected in the liquid storage tank, non-condensable gas is input into the organic matter permselective membrane group, the retentateside of the organic matter permselective membrane group is connected to the front end of the compressor, output lean gas is recycled after being coupled with supplementary nitrogen, the permeation side is connected to the condenser, and collected gas is coupled and recycled with tank truck outlet gas. According to the oil tank truck organic matter permselective membrane method cleaning system andthte operation process, an organic matter permselective membrane is used for the oil tank truck cleaning system, the nitrogen is recycled, oil in oil gas can be recycled, secondary pollution is avoided; and the final waste gas can reach the direct emission standard, the surrounding environment is not polluted, and great environmental and social benefits are generated.
本发明公开一种油罐车优先透有机物膜法清洗系统及运行工艺,氮气输送管路经压缩机、气体加热器连接至罐车;罐车出口连接至冷凝器;冷凝器出口同时连接至储液罐和优先透有机物膜组;冷凝器所得冷凝液去往储液罐收集,不凝气输入优先透有机物膜组,优先透有机物膜组的渗余侧连接至压缩机前端,输出的贫气与补充氮气耦合后循环使用,渗透侧富连接至冷凝器,集气与罐车出气耦合回收。本发明把优先透有机物膜用于油罐车清洗系统,氮气循环利用,油气中的油可回收,不产生二次污染。最终的废气达到可直接排放标准,不对周围环境造成污染,产生极大的环境和社会效益。
