Analysis and optimization of separation process of residual liquid from vinyl chloride rectification
The process of separating and purifying 1,1-dichloroethane from the residual liquid of vinyl chlo-ride rectification was simulated and analyzed by using process simulation software,and appropriate control parameters were proposed.The results show that by optimizing the production control according to the calcu-lated parameters,vinyl chloride in the residual liquid can be efficiently recovered,and the purity of 1,1-di-chloroethane can be increased to more than 98%.In view of the problems existing after the optimization of control parameters,further optimization solutions are proposed.
