An Apparatus for Determination of Solubility of Gases in Liquids under High-Pressure
Lu Xiuyang Wu Zhaoli (Department of Chemical Engineering, Zhejiang University)
An apparatus for gas solubility determination at room temperature under pressure was established. The apparatus proved to have shorter time to attain phase equilibrium owing to the dual countercurrent phase circulation by two magnetic pumps. Two sets of glass windows were fitted on the cell to facilitate the liquid level control Samples were collected on line. The dead space was minimized, and the temperature of the system was precisely controlled by thermostated bath. The reliability of the apparatus was tested by argon and nitrogen absorption, the reproducible data were obtained within the error of 1%.
