Computer-Aided Conceptual Design of Batch Distillation Systems

Abstract

During the past decade, several authors worked in the development of methods to cope with different steps of the design and synthesis of batch distillation systems. Among these methods, the conceptual design is based both on the thermodynamic analysis of residue curve maps and on the behavior of composition profiles in batch columns operating at limiting operating conditions, i.e., infinite number of stages and total reflux. In this work, we apply the conceptual design approach to design the recovery of 2-propanol from a mixture containing water by using cyclohexane as entrainer. All the computations were performed through an integration of these methods in a software tool for conceptual design.
