ASSESSMENT OF CHANGE IN TORQUE OF STREAM-BUBBLE CONTACT MASS TRANSFER DEVICES

A stream-bubble contact device for mass transfer apparatuses that enhances the efficiency of mass transfer processes is proposed. This device uses the energy of liquid streaming from the top downward, which reduces vapor (gas) phase hydraulic resistance. Also, because of reduced separation space, the overall dimensions of mass transfer apparatuses with the installed stream-bubble contact devise decrease. The results of change in torque, with due account of change in characteristic parameters of the contact device, are reported.
