Open publisher page 1 citations

Abstract

Considering the poor separative ability of low boiling distillation in a PVC plant which has a production capactity of 260 kt/a.The application of high efficient flow-guided sieve tray in the innovation of poly-chlorethylene distillation column was introduced,and its machinery characteristic was analyzed.Its operational performance was studied too.The advanced simulative software was used to optimize and simulate the innovation project.The result indicated that the application performance of high efficient flow-guided sieve tray was far better than the former conventional tray.After the innovation,the process capacity rose to nearly twice as the predecessor's capacity,with the efficiency evidently improved,and the energy consuming decreased enormously.
