The Mixed Integer Non-Linear Programming for Combined Heat and Mass Exchanger Network Synthesis with The Effect of EMCD and EMAT on Economic Analysis

Abstract

The Combined Heat and Mass Exchanger Network Synthesis (CHAMENS) which comprised a win-win strategy simultaneously diminishing the emission alongside maximizing the profits of the whole systems has been accomplished in this work. The novelty comes from the development of the original stage-wise superstructure (SWS) to be able to overcome the problems including detailed cost considerations by using more accurate formularies to determine the exchanger configurations, initializations, favorable boundaries to solve the complexities, eradicate the number of the heat and mass exchangers, and decrease the TAC. The purpose of this work is generate the new applicable method which is noticeable and flexible to be implemented with a better accuracy output for the case studies, MENS, HENS, CHAMENS using GAMS. The Total Annual Cost (TAC), the number of units needed, some advantages and limitations of each method have been compared and analyzed. The results for the application of this work in CHAMENS have been achieving a significant TAC reduction of $ 235,306 a⁻¹ for a year operational time compared to the floating pinch method.
