One of the most effective ways of energy saving is to upgrade the existing heat-mass transfer devices. To increase the efficiency of mass-transfer apparatus, a stream-film (bubble) contact device is suggested. The paper considers the prospects of using stream-film contact devices for heat-mass transfer apparatus. The distinctive feature of the developed device is an intensive countercurrent contact between the gas and liquid in each element. Dependences of the volume flow rate of gas involving turbulence in the flow volume at different design parameters are set.
