Multiobjective optimization of simulated moving bed reactor and its modification - Varicol process

Abstract

A comprehensive optimization study on a Simulated Moving Bed Reactor (SMBR) system is reported in this article for the direct synthesis of Methyl Tertiary Butyl Ether (MTBE). In addition, the SMB technology, which is based on synchronous switching of ports, was modified to a new more flexible Varicol process based on non-synchronous switching. Multi-objective optimization has been performed for both SMBR and Varicol and their efficiencies were compared. A state-of-the-art optimization technique, viz., Non-dominated Sorting Genetic Algorithm (NSGA) that allows handling of these complex optimization problems is employed in this study.
