| Abstract: | The liquid holdup and the unstable vapor pressure were studied in the process of batch distillation DMSO production and in the original process equipment. A method using large back pressure tower and refluxthe recovery operation to effectively solve the problems was presented. The experimental results showed that through shortening the time of qualified products, improving product quality, and increasing of a single batch number of products, good economic benefits can be achieved. |
