Abstract
This chapter presents a study in which a pilot plant with the capacity of 2 ton CO2/day was constructed using chemical absorption process to separate CO2 from flue gas of a thermal power plant. The pilot plant in this study adopted the absorption and stripping using the recycle separation process. Recovery of CO2, one of the main parameters, was experimented at different temperatures and flow rates of flue gas and absorbent, monoethanolamine (MEA). MEA was used as an absorbent and evaluated of its absorption characteristics in a series of experiments giving some kinds of variations like temperature and flow rate of MEA, temperature and rate of flue gas, and MEA concentrations. When the temperature of flue gas was increased by 10 m3/hr, from 30 m3/hr to 40 m3/hr, CO2 recovery ratio was decreased by around 5%. CO2 recovery ratio was maintained stably at both 15wt% and 25wt% of MEA concentration over 2.5 m3/hr of MEA flow rate.
