Simulation and Experimental Research of Cyclohexane Isopropyl Alcohol Azeotropic Solvent Separation During Chemical and Pharmaceutical Process

Abstract

In this paper, a cyclohexane-isopropanol azeotrope separation process was studied, respectively general simulation the separation process. The steady-state pressure swing distillation process, while at the laboratory of transformer rectification section, reduction pressure distillation column and intermittent small scale experimental atmospheric tower portion. Salt pressure swing distillation experiments, have achieved good results. This article will use dynamic simulation of distillation processes to separate these two processes in line, especially in heterogeneous batch azeotropic distillation and batch extractive distillation, distillation is an attempt to design and method of open up. The general process for separating a cyclohexane-isopropanol azeotrope was simulated optimization studies, including a total theoretical plate number of each section of the tower. Each column operating parameters have been best products of cyclohexane and isopropanol concentrations were reached more than 99.9wt%.
