Carbon dioxide (CO2) emission contributes largely to the increasing level of greenhouse gases in the atmosphere. Carbon capture and storage (CCS) and carbon capture utilisation (CCU) are evaluated as a fundamental technology that contributing to the reduction of CO2 emission. Thus, this study concerns about the design of 50,000 tonnes/year of methanol using pre-combustion CO2 capture technology. Aspen HYSYS version 8.8 was used as a tool for simulating the methanol production process. The simulation mainly covered the pre-combustion CO2 capture technology using Selexol method and methanol production plant from CO2 as raw material. The methanol plant electric capacity was evaluated based on the capacity of three coal-fired power stations in Malaysia. The CO2 was fed at 120 kPa and H2 at 101.3 kPa, into the methanol plant which resulted in 21.9% purity of methanol and water. The CO2 need to produce targeted 50, 000 tonne/year of methanol is 1500×104 kg/hr. The emission of CO2 by the Sultan Salahuddin Abdul Aziz Shah Power Station is 326 kg/hr which produce 0.09 kg/hr of methanol.
