Investigation liquid-side controlled mass transfer

In investigation of tiie liquid-side controlled mass transfer using desorption of CO2 from water as model system, the small head tank (2S) is used. The liquid after the pump (22) enters the pipe (23), where through die valve (26) CO2 frxim the gas bottles (27) is fed. (llie respective pipe is not presented in Fig. 2.) The carbon dioxide is separated in the head tai (25). Through the pipe (24) die saturated water flows to the ratameters (18). The surplus water overflows through the pipe (13) in the bottom of the column (7). 

The investigations of Murrieta [268] tiiow that for calculation of the liquid-side controlled mass transfer coefficient in case of corrugated packii the Higbie penetration model (Chapter 1) can be used, when the erqmsure time 0g in it is calculated the equaticm... 

In another paper Benadda et al. [29S] find that the partial mass transfer coefficient for the liquid phase is not defending on the pressure in the interval fiom 0.1 to 1.3 MPa. The investigation was carried out with the same packing and the same column. That is, the pressure is not influencing the liquid-side control processes.
