Modelling and Simulation of Multistage Flash Desalination Plants

الملخص

This study describes the mathematical model developed for evaluating the performance of multistage flash (MSF) desalination plants at steady state operation. The governing equations are linearized and are arranged in a tridiagonal matrix form. The solution of these equations are obtained by a computer code written in visual basic language with friendly user format developed for this purpose. This code can predict the plant productivity with profiles of temperatures and flow rates for all stages in the unit. The present results were compared with some previous results presented in literature, and with the design data of MSF plant existed in Benghazi city. The comparisons show good agreement with these available data.
