氯苯储罐挥发量损耗计算及降低措施

Calculation of Volatile Loss of Chlorobenzene Storage Tank and Measures to Reduce

氯苯储罐呼吸阀排放氯苯气不但造成物料损失,还会增加后续废气处理系统的运行负荷,增加超标排放的风险,导致污染环境事故发生。降低储罐区氯苯排放是节约资源减少损失的需要,保护大气环境的需要。氯苯气作为一种具有一定毒性的气体,在现有的主流处理工艺中,工厂在处理氯苯气时,大多采用燃烧后碱洗或活性炭纤维(ACF)吸附处理方式;考虑到燃烧过程中存在燃烧不充分,形成新的有毒有害物质,对环境造成二次破坏,因此采用活性炭纤维吸附-蒸汽脱附-冷却再生处理的方式,但也存在吸附效率下降,导致废气超标排放的风险。

The chlorobenzene gas discharged from the breathing valve of the chlorobenzene storage tank not only causes material loss,but also increases the operating load of the subsequent waste gas treatment system,increases the risk of excessive emissions,and causes environmental pollution accidents.Reducing chlorobenzene emissions from the storage tank area is the need to save resources,reduce losses,and protect the atmospheric environment.Chlorobenzene gas is a certain toxic gas.In the existing mainstream treatment process,most factories use alkaline washing after combustion or activated carbon fiber(ACF)adsorption treatment when processing chlorobenzene gas;considering the combustion process Insufficient combustion exists in the system,forming new toxic and harmful substances,causing secondary damage to the environment.We use activated carbon fiber adsorption-steam desorption-cooling regeneration treatment,but there is also a decline in adsorption efficiency,which leads to excessive exhaust emissions.risks.
