Abstract

Renewable energy such as geothermal is very effective in reducing the effects of greenhouse gas emissions. Therefore geothermal-based multi-generation system can be used to produce commodities for cooling, power, hydrogen and water desalination system combined with liquefied natural gas as a cold energy recovery. To assess the performance of the system of the multigeneration system used, energy analysis, exergy, exergoeconomic and exergoenvironmental are needed. Also used is single and multi-objective optimization, done by Engineering Equation Solver (EES) and MATLAB softwares.

The results to be achieved or the hypothesis of the multi-objective optimization and artificial neural network multi-generation system, are: energy analysis, exergy, exergoeconomic (in the form of cost in each unit) and exergoenvironmental. Constraints used are geothermal temperatures, steam fraction and MER. The higher thermal efficiency can be achieved by increasing the vapor generator pressure and evaporator temperature or decreasing mass extraction ratio, separator pressure 2, turbine inlet pressure 2, geothermal inlet temperature, vapor generator terminal temperature difference and ammonia based concentration.
