摘要
为了解决油库油气回收系统处理能力不足的问题,以原处理量为300 m^3/h需达到600~700 m^3/h的吸附式系统为例,比选了四种改造方案,确定了利用闲置的与现用装置相同的两个吸附罐和一个真空泵与原有设备并联运行的扩能方案。改造后处理能力可满足扩能需求,经检测油气回收率达到97.2%,气体排放质量浓度达到2.99 g/m^3,均符合GB20950—2007《储油库大气污染物排放标准》。该方案简单易行,费用低廉,油气回收效果好,具有广阔的推广前景。
In order to solve the problem of insufficient capacity of oil vapor recovery system in an oil depot,4 kinds of revamping schemes were compared,and a technology scheme adopting an idle adsorption tank,vacuum pump with original oil vapor recovery equipment in parallel installation was determined. After the transformation,the oil vapor recovery and processing capacity could meet the operation requirements,the average recovery rate of oil vapor was improved,and the gas discharge could meet the requirements of the relevant standards. The scheme was simple,convenient,low-cost with sound oil vapor recovery effect,and was worth popularizing.
