| Abstract: | The CO2 loading in aqueous mixtures
of diethanolamine (DEA) and piperazine(PZ), from a mixture of CO2
and N2, has been measured for total amine concentrations and mole
ratios of PZ to total amine ranging from 2.0 to 3.0 M and 0.01 to 0.20,
respectively, at 313.14 K and 15.199 kPa CO2 partial pressure. Measurements were made by a
saturation method using a laboratory scale bubble column. The results of CO2
loading are expressed as XCO2 (mole CO2/mole of total
amine) for all experimental runs. A model is given to predict the CO2
loading in aqueous mixture of DEA and PZ. The model predictions have been in
good agreement with the experimental data of CO2 loading in aqueous
mixture of DEA and PZ with the average deviation of 8.67. |
