Simulation on removal of carbon dioxide from coal power station: article

Removal of carbon dioxide (CO₂) from Coal Power station has been discussed and simulated using Aspen HYSYS V8.8. This research was executed in order to investigate the consumption of energy in order to remove CO₂ emitted from Coal Power Station and to improve the efficiency of CO₂ removal from Coal Power Station by using aqueous blended solvent between monodiethanolamine (MDEA) and sulfolane. From the simulation that has been executed, it can be said blended solvent of MDEA-Sulfolane is the most efficient solvent to treat CO₂ when it is compared with other single solvent such as MDEA, DGA, DIPA, TEA, MEA and DEA. This is because the result obtained from this research shows that MDEA-Sulfolane used the lowest amount of energy to treat CO₂ when it is compared with those amine solvents with flowrate of 2000x10⁵ kg/h. This research also shows that the most suitable amount of blended MDEASulfolane and water to be used is 19%,1% and 80% respectively.
