摘要
针对加油站收油和发油过程中产生的油气污染,分别采用玻璃态油气截留型PEEK中空纤维膜组件和橡胶态油气渗透型GMT板框式膜组件,在自行设计建造的膜分离设备上,对比考察了2种膜组件和整个膜系统对油气污染治理和回收的效果.结果表明,2种膜系统对VOCs/空气混合气有很好的净化能力,尾气能够达标排放;在富油气返回油罐的模拟加油站实际运行情况的循环实验条件下,尾气也低于25 g·m-3的国标.
Two kinds of membranes modules,vapor retained glassy membrane based on PEEK hollow fiber membrane modules and vapor permeated rubbery membrane system based on GMT plate-and-frame membrane modules,were used to control the oil vapor pollution during the course of receiving and transferring gasoline in oil station.The efficiencies of the membrane module and the membrane system of them were evaluated and compared respectively in the facilities which were developed by ourselves.It was found that both the two kinds of membranes modules had high efficiency for the separation of VOCs-air mixed gases,and the outlet vapor after treatment all can meet the national standard.When the vapor-enriched gas was returned to the oil tank to simulate the continuously cycle test,the concentration of VOCs in the outlet was also below 25 g·m-3.
