固定顶储油罐VOCs回收治理技术及前景分析

Treatment technology and prospect analysis of VOCs recovery in fixed-roof storage tank

固定顶储油罐是油田站场中存储原油的重要设施,因其受到自身及外界因素的影响存在一定的呼吸损耗,挥发性有机物(VOCs)无组织排放到大气中,不仅造成了能源的浪费,也给人类生存和社会环境造成了严重影响。采用大罐抽气装置可以很好地解决这一难题,通过HYSYS软件模拟工况,确定固定顶储油罐的蒸发损耗量,并优化生产运行,研发油田地面工程集输系统密闭流程,以减少油气挥发;保障了油田的安全生产,同时可以创造较高的经济价值。VOCs回收治理对油田可持续发展和绿色环保具有重要意义。

The fixed-roof storage tank is an important facility for storing crude oil in oilfield station.Due to the respiratory loss caused by internal and external factors,the volatile organic compounds(VOCs)are discharged into the atmosphere without organizationIt,which not only causes a waste of energy,but has a serious impact on human survival and social development.However,adopting the large tank extraction device can be a good solution to this challenge.By simulating the working condi-tion with HYSYS software,the evaporation loss of fixed-roof storage tank can be determined,and the production operation can be optimized to realize the closed process of gathering and transportation system of oilfield surface engineering and reduce the oil and gas volatilization loss.Additionally,it can not only ensure the safe production of oilfields,but create higher economic value.Even more to the point,the recovery treatment of VOCs is of great significance to the harmonious,green and sustain-able development of oilfield.
