Absorption of co2 by single and blended amine solvents in various gas liquid contactors

Abstract

In this work the absorption of CO2 into aqueous solutions of sterically hindered and blended amines is considered A kinetic study is carried out for the reaction of CO2 into aqueous solutions of two important single sterically hindered alkanolamines 2 piperidineethanolamine 2 PE and 2 amino 2 hydroxymethyl 1 3 propanediol AHPD at 303 313 and 323 K for a range of amine concentrations using a fabricated wetted wall column absorber The reaction is satisfactorily described using a zwitterion
