Abstract
A model for combined mass and heat transfer during nonisothermal absorption of a one component gas in a vertical gas-liquid slug flow with liquid plugs containing small bubbles is suggested. Under the assumptions of a perfect mixing of the dissolved gas in liquid plugs and uniform temperature distribution in liquid plugs, recurrent relations for the dissolved gas concentration and temperature in the n-th liquid plug and mass and heat fluxes from the n-th unit cell of gas-liquid slug flow are derived. The total mass and heat fluxes in a gas-liquid slug flow are determined. In the limiting case of absorption without heat release the derived formulas recover the expressions for isothermal absorption in a gas-liquid slug flow with liquid plugs containing small bubbles. In the limiting case without small bubbles in the liquid plugs the derived formulas for mass and heat transfer during gas absorption in slug flow with small bubbles in liquid plugs recover the obtained expressions for mass and heat transfer in slug flow without small bubbles in the liquid plugs.
