高压尾气隐患的治理

Accident potential management of high-pressure off gas

某炼化企业的醇酮装置是生产精己二酸的重要装置。装置扩能改造后,生产负荷提高,导致高压洗涤塔D1运行时出现尾气夹带洗涤油的现象。针对这一安全隐患,车间工艺人员在高压洗涤塔后增加尾气脱液罐S3,尾气在罐中充分进行气液分离,改善了现场作业环境的同时消除了安全隐患,并且回收洗涤油约11.1t/a。

The cyclohexanol and cyclohexanone unit is important in a petrochemical company to produce adipic acid.The growing capacity of the unit after revamp leads to wash oil entrapping in the off gas in high-pressure wash tower D1.According to the accident potential,an off gas fluid-loss tank is added after the high-pressure wash tower to separate gas and liquid adequately.The measures improve the operating environment and remove the accident potential,furthermore,the wash oil can be recovered by 11.1t/a.
