✦ Synopsis

First and second law of thermodynamics analysis was presented for direct boiler driven multistage flash (MSF) desalting svtem. The analvsis indicates that direct suvvlv of low prekuie steam to-MSF plant is wasteful process twith boiler second law efficiency less than 20%). Dual purpose power desalting plants with cogenration turbines are presented and analyzed.

The available energy concept and second law analysis are used rate the power cycle, MSF desalting unit and the whole dual vurnose slant. It was found that bleeding steam from the turbine t'o the desalting plant saves up to 60% 0': thermal energy when compared to boiler driven MSF plant. limitation of The advantages and the steam power cycle combination were gutlined and discussed.
