Design Parameters Affecting the Commercial Post Combustion CO2 Capture Plants

AbstractA comprehensive design exercise for a 4,500 TPD CO2 capture plant is conducted based on coal flue gas streams at three recovery rates ranging between 80% and 90%. Three solvents (30wt% MEA, HTC formulated solvents RS-2™ and RS-1210) and enhanced configurations are utilized to achieve the production capacity at minimum emission to atmosphere and minimum energy consumptions. Design parameters and performance comparison of different scenarios are presented in terms of flue gas rates, solvent circulation rates, cooling duties, steam consumption, electricity consumption, main equipment sizes, and emissions to atmosphere
