Abstract

The purpose of this study is to design and analyze a coal-fired power plant that includes a CO₂ capture unit from flue gas and synthesizes methanol in a calciner reactor, thermodynamically and techno-economically. The thermodynamic analysis is conducted by using the Aspen Plus software. The useful outputs for the presented system are CH₃OH and electricity. Some parametric analyses are made to find the crucial properties of the plant. The total exergy and energy efficiencies of the plant are found to be 0.86 and 0.85, respectively.
