Abstract
Experimental study was carried out on direct-contact mass and heat transfer between vapor and liquid with change of phase, that is, simultaneous condensation of organic vapor and evaporation of water or evaporation of water alone in a bubble column equipped with gas dispersion nozzles. The systems used in this experiment were carbon tetrachloride-water and trichloroethylene-water, which were immiscible in the liquid phase.
Volumetric coefficients of vaper phase mass transfer were measured and compared with previous work.
From the experimental results, condensation and evaporation rates were calculated under the given operating conditions and the effects of these specified operating conditions on these rates were made clear.
