Case File for Solar Assisted Catalytic Conversion of CO2 Methanol Model

This study focuses on the Besmaya Natural Gas Combined Cycle (NGCC) power plant in Baghdad, Iraq, using Aspen Plus software to simulate plant operation and establish a baseline. A post-carbon capture strategy is then implemented, converting CO2 from flue gases into methanol through catalytic conversion with H2. Methanol has diverse applications in industries such as pharmaceuticals, plastics, and agriculture, making it valuable for CCU processes. H2 for the conversion is produced using a solar-water splitter technique, utilizing condensate from the power plant's steam turbine system. Solar potential at Baghdad coordinates is assessed using the System Advisory Model (SAM). This research demonstrates the importance of CO2 capture and methanol production in improving the environmental profile of NGCC power plants. Integrating solar-driven processes reduces greenhouse gas emissions and yields valuable products, contributing to a more sustainable energy paradigm.
