NATURAL GAS PRODUCTION FIRED COMBINED CYCLE POWER PLANT DEVELOPMENT OF TRI-GENERATION ENERGY, COOLING AND SAFE WATER BY RECOVERING HEAT GENERATED: A TECHNICAL AND ECONOMIC EVALUATION.

Abstract: One of the most effective methods for maximizing the use of available energy is trigeneration. This research study examines the use of waste heat (flue gases) released by the Afam V1 gas turbine power plant for the simultaneous production of electricity, clean water and cooling using a single stage vapour absorption chiller (VAC) by combining steam with a Rankine cycle and a heat recovery steam generator (HRSG). The trigeneration system's main source of energy comes from the flue gases released during the gas turbine power cycle. The thermal energy recovered from the steam cycle's condenser and the extra heat present in the flue gases are used to power desalination and cooling cycles that are tailored to the villas' specific cooling requirements. The trigeneration system's financial and environmental advantages in terms of savings in expenses and a decrease in carbon emissions were examined. The trigeneration system achieves energy efficiency of around 82%-85% as opposed to combined cycles at 50%-52%. Implementing a waste thermal recovery tri-generation system reduces standardized carbon dioxide emission per MWh by 51.5%. The payback period for the trigeneration system is 1.38 years, and its total net present value for the duration of the project is $66 million.
