This study uses the application of Pinch analysis to optimize an integrated electrolyzer and methanation system, a promising approach for producing green hydrogen synthetic natural gas (SNG). By leveraging renewable energy sources, such as wind solar, electrolysis is used produce hydrogen, which reacts with captured carbon dioxide in reactor form methane. process not only allows efficient storage but also supports reduction greenhouse emissions. A key focus this optimization thermal flows within has been extensively addressed literature. was applied identify critical point, revealed temperature at most heat recovery could be achieved. The design tailored exchanger network led significant improvements, including 66.45% hot utility consumption 18.85% cold demand. Overall, system achieved global savings 31.02%. These results were compared existing literature, demonstrating that our offers comparable or superior while addressing challenges, complexity chemical reactions integration. research highlights potential substantial operational cost reductions increasing sustainability industrial applications, contributing advancement technologies decarbonization systems.
