INTEGRATION OF TVC DESALINATION SYSTEM WITH COGENERATION PLANT: PARAMETRIC STUDY

The aim of this research is to perform a parametric analysis on TVC desalination system. The study was based on first and second law of thermodynamics. Four units of thermal vapor compression (TVC) desalting system, from Sidem, with a capacity of 1 MIGD and a gain ratio of 8 were utilized. This system was considered to be integrated with the Azzour South cogeneration plant. Several parameters were investigated in this study; compression ratio, temperature difference across the stages and number of stages. Results showed that the gain ratio, exergy destruction were sensitive to the variations of those parameters. Results also showed that the evaporator and steam ejector are the main sources of exergy destruction occurred in TVC system. The study recommends that efforts should be directed to achieve the best setting for the desalination process to minimize the exergy destruction and increase the gain ratio by improving design of such components.
