In the reaction process of producing * * *products, the hydrogen chloride gas which is absorbed by water to generate hydrochloric acid solution. In this process, part of xylene vapor escapes, thereby obtaining a mixed solution of xylene and hydrochloric acid.
This company requested to separate xylene and hydrochloric acid. That time, the equipment used reaction kettle, which is inevitably entrained due to human operation during the separation process. In addition, the process of the reaction kettle using the principle of gravity separation is slowly, the separation efficiency is low and the separation is not complete, therefor in the separation of xylene in the hydrochloric acid solution.
