(2.School of Physical Science and Technology, Xinjiang University, Urumqi, Xinjiang, China 830046)
【Abstract】An experimental apparatus based on isochoric saturation method was developed for measuring gas solubility and volumetric mass transfer coefficient in liquid with expanded uncertainties of temperature, pressure, solubility and volumetric mass transfer coefficient at 0.02 K, 0.01%, 2%, and 4%, respectively. The solubility and volumetric mass transfer coefficients of CO2 in 1-pentanol were determined at temperature from 323 K to 343 K and at pressure from 0.9 MPa to 5.0 MPa. CO2 solubility in 1-pentanol increased with the increasing pressure. Mole fraction of CO2in 1-pentanol was increased by 26% at 323 K, when pressure was increased from 2.5 MPa to 3.2 MPa. However, CO2 solubility of in 1-pentanol decreased with the increasing temperature. Mole fraction of CO2 in 1-pentanol also dropped by 26% at pressure of 0.9 MPa when temperature was increased from 323 K to 343 K. Volumetric mass transfer coefficient of CO2 was increased with increasing temperature and pressure. The CO2 volumetric mass coefficient showed an increase from 0.008 9 s−1 to 0.017 5 s−1 when temperature changed from 323 K to 343 K and pressure from 1.1 MPa to 5.0 MPa, respectively.
