In gas-liquid system, the bigger the resistance ratio of liquid side to gas side is, the more remarkable the enhancement of mass transfer by Marangoni effect becomes.

As the marangoni effect is easily masked by the presence of a small amount of surface active impurities, it should first be tested whether the experimental gas-liquid system is contaminated or not.

The function of the phase separator is to simply divide the liquid and gas and then vent the gas from the system.
