The storage gas pipe is filled with the gas to be studied (CO2) at 500 kPa (gauge) and then heated to the specified temperature.
The temperature of metal flange was kept a little higher (+0.3 K) than that of the liquid to
avoid condensation on the surface of the metal flange.
After approximately 1 hour, the equilibria of both temperature and gas-liquid are reached, CO2 is introduced into the chamber in 5 s and the absorption starts immediately.
The total gas pressure, the temperatures of the liquid and gas phases and the agitation speed (rps) in the reactor are recorded using a data acquisition system (data logger, Agilent BenchLink 4972A).
The partial pressure of the gas A at the experimental condition was corrected for the vapor pressure of the solution as follows.
