Research and application of pressure difference method for deep desorption of hydrochloric acid
This paper introduces the source of by-product acid from vinyl chloride synthesis,expounds the process principle and technical characteristics of hydrochloric acid deep desorption technology,and summa-rizes the operation of differential pressure method hydrochloric acid deep desorption device.The results show that the purity of hydrogen chloride gas desorbed by the device is more than 99%,and the content of hydro-gen chloride in the desorbed recycled water is less than 1%,which can be reused completely,and the prob-lem of acid and water imbalance in the process of vinyl chloride synthesis is completely solved.
