Webb1 sep. 2024 · Section snippets Chemical and phase equilibrium. In order to simulate and model CO 2 absorption in amine solutions, CO 2 solubility should be estimated by both chemical equilibrium and physical solubility in water and amine solvents (Zhang and Chen, 2011a). In fact, thermodynamic equilibrium is expressed by combining the conditions for … Webb1 jan. 2016 · The aim of this work was to find out the carbon dioxide (CO 2) gas solubility in 20 wt. % aqueous piperazine (PZ) solution. For this purpose, SOLTEQ BP 22 solubility cell was used and experiments were conducted at temperatures (313.15 and 333.15) K by varying the pressure of CO 2 from 2 to 10 bar. The experimental results of solubility (mol …
