Thermodynamic optimization of multi-effect desalination plant using the DoE method

Thermodynamic optimization of a multi-effect desalination (MED) plant has been performed. The effects of feed water flow rate, temperature of seawater, numbers of effects, temperature differences of preheaters and the outlet pressure have been studied. Tables for numerical calculations have been designed based on the DoE method. The effects of the foregoing parameters on the maximum and minimum distilled water have been investigated. In addition several contours have been presented to help a designer to find suitable conditions for a plant design.
