PROYECTOS DE EFICIENCIA ENERGETICA APLICANDO TURBOEXPANDERS A CICLOS COMBINADOS EN ESPAÑA

Abstract

This paper presents a feasibility analysis of the power generation through the expansion of high pressure and flows of natural gas in the regulations stations of CCGTs power plants in Spain. Based on their yearly production we can predict the potential generation in the turboexpanders. Based on thos calculations we conclude that only those CCGTs maintaining high yearly production can improve 0,2% their energey efficieny, reducing costs, incrementing benefits with payback in less than 2 years. Environmental impact is improved by CO2 and NOX emmisions reduction per Mwh produced.
