This is the first paper of a series of articles that deals with the modeling and optimization of dual-purpose desalination plants which combine thermal desalination processes and combined heat and power systems, specifically solid oxide fuel cell SOFC electricity generators. This paper presents preliminary results obtained for the multi effect evaporation (MEE) process (stand alone process). The steady state performance of the MEE system is described by a simplified and no linear programming (NLP) model. Optimal operating conditions including profiles of temperature, flow-rate and heat transfer area along the evaporator are analyzed. In addition, the influence of the effect number on the evaporation efficiency is also investigated.
