Thermodynamic analysis of combined cycle power plant standalone and coupled with multi effect desalination with thermal vapor compression

This paper discusses the thermodynamic analysis of a combined cycle power plant (CCPP) alone and coupled with multi effect desalination thermal vapor compression (MED-TVC) desalination plant, modelled using the IPSEpro software package based on operational duties for the CCPP and MED-TVC and validated against the vender and the work of Kamali respectively. Relative differences between the model results and vender data were found to be below 3.7 % in both models. The impact of the environment on both configurations was studied. The results showed that the environment has a clear impact, especially when ambient temperature raises the plant efficiency and power output decreases by about 0.419% and 5.3% every 10°C ambient temperature increases. However, CO2 emissions increase with a rise in temperature, while there is a slight improvement in performance and CO2 emission decreases when the relative humidity increases.
