Development of an Efficient Linear Model for the Analysis of Multiple Effect Evaporator System

Abstract

Based on the principles of Process Integration a simplified model has been developed for the analysis of multiple effect evaporator (MEE) systems. It uses the new concepts of stream analysis, temperature path and internal heat exchange for the formulation of the model equations. In addition to it, the above model also takes into account variation in physico-thermal properties as well as boiling point rise while simulating the MEE system. The present model is scalable and is used to simulate three case studies, taken from open literature. The model, consists of linear equations, which are automatically generated through the computer program and are solved using Gaussian Elimination method with partial pivoting. The results of the present model compare well with published models.
