氯气液化排污系统技术改造

Technical transformation of liquid chlorine emptying in chlorine liquefaction

给出原氯气液化排污系统工艺流程图。原有排污系统中,三氯化氮沉降不明显,管道腐蚀严重。提出整改措施,改造排污设备,改装三氯化氮处理管路,并给出改造后排污系统工艺流程。改造后,节约了维护费用,提高了产品市场竞争力。

The process flow chart of the original liquid chlorine emptying system in chlorine liquefaction is given.In the original emptying system,nitrogen trichloride deposited non-obviously,and the pipeline corrosion was serious.Rectification measures were put forward to transform the liquid chlorine emptying equipment,to refit the nitrogen trichloride treatment pipeline.The technological process of the reformed emptying system was given.After the transformation,the maintenance cost was saved and the market competitiveness of products was improved.
