چکیده:

Removal of acid gases contaminants from natural gas is vital in gas treatment processes. Using a high pressure cell, vapor-liquid equilibrium data for the solubility of CO2 in aqueous mixture of(24 to 36 wt%) diisopropanolamine (DIPA), (7 to 13 wt%) 2-amino-2-methyl-1-propanol (AMP) and (2 to 8 wt%) piperaizne (Pz) as well as 45wt% diisopropanolamine at 313, 328 and 343 K andpressure range of 1 to 40 bar are obtained. The results are presented as the partial pressure of CO2 against acid gas loading (mol CO2/mol amine). It’s observed that blend of 2-amino-2-methyl-1-propanol (AMP) and piperzine (PZ) increases the CO2 loading in aqueous DIPA solution
