Abstract
Abstract The feasibility of using high-efficiency structured packing in CO 2 separation processes with a newly proposed solvent, 2-amino-2-methyl-1-propanol (AMP), was investigated. The packing performance was evaluated in terms of overal mass transfer coefficients of CO 2 absorption into aqueous sodium hydroxide and AMP solutions over ranges of main operating variables, i.e. up to 10 kPa partial pressure of CO 2 , 0.29–0.61 m 3 m −2 s −1 gas rate, 4.87–14.18 m 3 m −2 h −1 liquid rate, and 1.1–2.0 kmol m −3 liquid concentration. The experimental results showed that the structured packing provides 10 to 33 times higher overall mass transfer coefficients than commenly used random packings.
