Designing of 50000 tons per year methanol production plant using oxyfuel combustion CO₂ capture technology

Emissions of greenhouse gases (GHGs) is a serious environmental issue which have become worldwide problems. Global warming is occurred when in the atmosphere, level of carbon dioxide (CO₂) increased. The planet become warmer than it would be naturally because of more heat is trapped by the atmosphere. Carbon dioxide (CO₂) is one of the main greenhouse gases (GHGs). Nowadays, about 85 percent from world energy consumption is contributed by fossil fuels. The combustion of fossil fuels produced carbon dioxide (CO₂). Therefore, to reduce both carbon dioxide (CO₂) emissions and fossil resource depletion, capture carbon dioxide (CO₂) and use it as an alternative carbon feedstock for chemicals, fuels and materials have the potential. The objectives of this research are to design methanol production plant using oxy-fuel combustion CO₂ capture technology and to evaluate methanol production capacity form different power plant in Malaysia using oxy-fuel carbon capture technology. By using carbon dioxide (CO₂) that has been capture using oxyfuel combustion capture technology as raw material, methanol is produced. This research is to design methanol production plant using oxy-fuel combustion carbon dioxide (CO₂) capture technology in order to produced 50000 tonnes per year by using Aspen Hysys Software. Then, from the research, methanol production capacity from different power plant in Malaysia using oxy-fuel carbon capture technology is evaluated. About 4700 kg per hour carbon dioxide is required to produce 50000 tonnes per year of methanol. Small plant which is less than 100MW capacity is enough for methanol production.
