Question
a) Deleye and Froment (1986) have reported the data on absorption of CO2 in aqueous solution of monoethanol amine (MEA) in a packed bed absorber. Gas containing CO2 at a partial pressure of 2 atm is to be purified by absorption into an aqueous solution of MEA in a packed bed filled with 5 cm diameter steel pal rings. Assuming excess concentration of MEA in a solution, the reaction between CO2 and MEA is treated as pseudo-first order reaction with rate constant k = 7.194 x 104 s1. A quantity of 6500 m/h of gas is treated with 1000 m3/h of MEA solution. Partial pressure of CO2 is to be reduced to 0.02 bar. Column diameter is 2 m and it is operating at a pressure of 14.3 bar and a temperature of 315 K. Calculate the height of the bed. The following data are reported. kG = 2.639 x 10º kmol/m²sPa KAL = 3.889 x 104 m/s %3D DAL = 2.39 x 10º m²/s ɛ = bed porosity = 0.45 Sp = specific surface area = 105 m²/m³ HA = Henry's law constant t = 4.89 x 106 m³ Pa/kmol
