Abstract

In the present work, a dynamic model is developed for the Multi-effect evaporator (MEE) to study the transient behavior of the system. Each effect in the process is represented by some variables which are related to the energy and material balance equ-ations for the feed, product and liquor flow. Backward feed is used for the development of the model for six effect evaporator system. For the steady state and dynamic simulation, the 'fsolve' and 'ODE45' solvers in MATLAB source code is used respectively.
