|Title:||Absorption of carbon dioxide into a mixed aqueous solution of diethanolamine and piperazine|
|Authors:||Mondal, M K|
|Abstract:||The CO<sub>2</sub> loading in aqueous mixtures of diethanolamine (DEA) and piperazine(PZ), from a mixture of CO<sub>2</sub> and N<sub>2</sub>, 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 CO<sub>2 </sub> partial pressure. Measurements were made by a saturation method using a laboratory scale bubble column. The results of CO<sub>2</sub> loading are expressed as X<sub>CO2</sub> (mole CO<sub>2</sub>/mole of total amine) for all experimental runs. A model is given to predict the CO<sub>2</sub> loading in aqueous mixture of DEA and PZ. The model predictions have been in good agreement with the experimental data of CO<sub>2</sub> loading in aqueous mixture of DEA and PZ with the average deviation of 8.67.|
