Abstract

First and second law of thermodynamics analysis was presented for direct boiler driven multistage flash (MSF) desalting system. The analysis indicates that direct supply of low pressure steam to MSF plant is wasteful process (with 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 purpose plant. It was found that bleeding steam from the turbine to the desalting plant saves up to 60% of thermal energy when compared to boiler driven MSF plant. The advantages and limitation of the steam power cycle combination were outlined and discussed.
