ABSTRACT

The separation of CO₂ from flue gas by alcohol amine method was investigated in this paper. We conducted the absorption and desorption experiments using different alcohol amines: monoethanolamine (MEA), diethanolamine (DEA), methyl diethanolamine (MDEA), triethanolamine (TEA), piperazine (PZ), and their binary mixtures. Relevant absorption rate and desorption rate of CO₂ were obtained and reported. Aspen Plus was applied to simulate the process of recovering CO₂ from flue gas via absorption of PZ-MEA solution. The influences of the lean liquid CO₂ load, lean liquid temperature and desorber pressure on the reboiler duty were investigated, and the optimal operating parameters were obtained on the basis of the minimum reboiler duty.
