The effectiveness of nozzles for mass exchange devices

Authors: A.F. Khairullin (BashNIPIneft LLC, RF, Ufa), V. A. Kuznetsov (Bashkir State University, RF, Ufa)

Key words: mass transfer of a column, a nozzle, organic glass, hydraulic resistance, efficiency, turbulization.

The article presents the researches of mass-transfer processes in the column apparatus with different attachments and their results. Experiments flow of liquid and gas phases are carried out, their hydraulic resistances are set. The authors defined the lowest value of the hydraulic resistance among nozzles: from Raschig rings and corner of nozzles. After processing the results of calculation the equations are obtained which satisfactorily describe the dependence of the coefficient of resistance of the load on the gas phase (from the Reynolds number of the gas phase). Promising corner nozzles, which help to improve the efficiency of mass transfer, are developed.
