Evaluation of Renewable Methanol Production Plant Design Using Tri-Pressure Stripper Configuration

Over the past years in the industry, the emissions of carbon dioxide (CO2) waste into the atmosphere have been rapidly increasing. The carbon capture technology is used in a few power plants to capture CO2molecules from the flue gas. Researchers have established method to use CO2and convert into valuable products. Therefore, this study is aim to simulate the reaction between captured CO2with hydrogen to produce renewable methanol. In order to achieve objective of designing the renewable methanol plant, the Aspen Hysys is used as modelling and simulation tool to obtain about 50k tonnes per year of renewable methanol production. Then, the amount of CO2is evaluated based on the amount of CO2in flue gas, CO2capture and renewable methanol produced. The results of the simulation that obtained is about 16510 kg/h of captured CO2and 6049 kg/h of methanol produced from the 17936 kg/h of CO2contained in flue gas. Three different coal-fired power plant capacities have been studied to evaluate their methanol production capacity. A small 110 MW power plant could produce 12705 kg/h of methanol, while 1400 MW and 2420 MW power plant will achieve 161,703 kg/h and 279515 kg/h respectively.
