Development and performance evaluation of a multi-generationsystem for power generation with desalination and hydrogenproduction units

The increase in environmental problems and the increase in populationhave caused energy researchers and scientists to think about the designand optimization of multi-purpose power plants in an integrated manner.The term multi-purpose means access to various goals in the field ofenergy and environment, such as power generation, fresh waterproduction, hydrogen production, pollutant reduction, and more.In this study, a power plant model has been investigated, whichincludes Brayton cycle, Rankine reheat cycle, organic Rankine cyclewith ammonia working fluid, electrolysis unit and desalination unit. Theoverall energy efficiency of the system was calculated as ۴۷.۴۶% and theexergy efficiency of the whole system was also calculated as ۴۵.۰۷%.The value of system stability coefficient is ۱.۸۲ and the total productionof carbon dioxide is ۰.۲۹۴ MWh/t. The most destroyed exergy is relatedto the combustion chamber with the value of ۱۶۰۵.۳ kW, the amount ofhydrogen and fresh water production is ۰.۰۰۳۶ kg/s and ۱.۲۹۲۳ kg/s,respectively.
