摘要
介绍了气相法白炭黑尾气吸收系统工艺流程简介及改进措施,通过改造洗涤分离器、酸碱吸收塔、增设除雾器、在线浓度计等措施,改进了尾气吸收的效果,提高了盐酸的浓度,减小了烧碱的用量,收到了较好的经济效益。
The technological process and improvement measures of the fumed silica tail gas absorption system were introduced. Through the improvement of washing separator, acid absorption tower and increase mist eliminator and on - line density meter such measure, the tail gas absorption effect was improved, the concentration of hydrochloric acid was increased, the amount of caustic soda was reduced, which received good economic benefits.
