Abstract

In this work, the thermoeconomic analysis is performed to assess the performance of a single effect-mechanical vapor compression desalination unit. Thermoeconomic equations based on Specific Exergy Costing (SPECO) method are developed for the analysis. The results show that the unit cost of the product distillate water is 2.59 $/m³ which is in a good agreement with that given in the literature. The effect of the escalation factor of the chemicals' cost on the product unit cost of the fresh water is investigated. The unit price of the product jumps to 3.56$/m³ at escalation factor of 7%. The influence of the compressor efficiency on the specific energy consumption and effectiveness is also investigated. The results show that there is an optimum compressor efficiency at which the product unit price is a minimum
