The systematic and quantitative approach on the environmental pollution is a significant challenge in highly regulated industries, such as power plants, where a large amount of waste gas including greenhouse gas must be discharged. Various CO2 reduction processes were simulated and the total cost of those were estimated. An environmental pollution impact was analyzed by the process operating conditions. The simulation of the CO2 reduction process for three absorbents (MEA (monoethanolamine), M-H amine solution, T-D amine solution) in the same operating condition was presented. The simulation results included CO2 recovery rate and CO2 mole fraction in CO2-rich gas of each absorbent. The efficiency of the M-H solution was almost same with the MEA solution ∼ 99% and the efficiency of the T-D amine solution was only 90%. When the reboiler duty of the M-H solution was changed 623 into 600 MJ/hr, the CO2 recovery rate was optimal and the energy consumption was decreased simultaneously. The total cost of the M-H solution process was lower than that of the MEA M-H solution process about $1602/yr. The suitability of each CO2 recovery process and the optimal operating conditions of CO2 reduction processes for a power plant was evaluated. This is an abstract of a paper presented at the AIChE Annual Meeting (Austin, TX 11/7-12/2004).
