Abstract
In this paper, effects on the performance of a combined gas turbine and organic Rankine cycle (GT/ORC) system of using thermophysical and thermochemical recuperation based on methane steam reforming (MSR) process is investigated from the viewpoint of thermoeconomics. For this purpose, three power generation systems consisting of simple GT/ORC, GT/ORC with thermophysical recuperators (TPR) and GT/ORC with thermophysical and thermochemical recuperators (TPCR) are proposed and compared thermodynamically and economically. In addition, the multi-objective optimization using genetic algorithm is conducted for the systems and the systems characteristics at the final optimum design points are compared. Resultsreveals that the thermodynamic, economic and environmental performance of all three proposed power generation systems are enhanced as the combustion temperature raises. In addition, the power generation system with TPR shows the best performance from the thermodynamic perspective with the 22.86% and 27.52% improvement in the exergy efficiency compared to the simple GT/ORC and GT/ORC with TPCR, respectively. However, under the operating thermodynamic conations obtained by the multi-objective optimization approach, the product cost associated with the system using TPCR is less than that of the other configurations.
