摘要
The CO2 loading in aqueous mixtures of diethanolamine (DEA) and piperazine(PZ), from a mixture of CO2 and N-2, 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 X-CO2 (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.
