| Summary: | C02 absorption for use in the bulk removal of C02 from C02-rich natural gas
(NG) was studied using an alternative absorbent: Piperazine (PZ) promoted 2-Amino-
2-Methyi-1-Propanol (AMP) blended solution. The absorption experiments were
conducted in a bench-scale absorption column packed with Sulzer metal gauze
packing. The process performance of the alternative absorbent was compared with the
MEA solution as a bench-marking absorbent at various operating pressures in the
range of 0.10 to S.OS MPa. The performances of the C02 absorption at high C02
partial pressure conditions were evaluated in terms of C02 removal efficiency and the
overall volumetric mass transfer coefficient for the gas phase based on unit mol
fraction driving force (K}a,). The influence of process parameters was studied for the
effects of C02 concentration in NG (30 - SO%), total gas flow rates (33 - SO
kmol/m2 h), liquid flow rates (2.89- 4.33 m3/m2.h), amine concentration (20 - SO
wt.%) and inlet temperature of liquid (303- 318 K). |
