Abstract
One of the ways of intensifying the heat and mass transfer processes in gas-fluid systems is designing jet-film contact devices with a developed surface of phase contact at high flow velocities. A contact jet-film device has been developed. The results of numerical investigation of the operation of this device are presented. There were determined the coefficients of heat transfer to the air from the surface of liquid inside of the drain cup of contact device. The criterion equations of convective heat transfer for engineering calculations of jet-film contact devices is corrected.
Highlights
Various heat-mass transfer processes and apparatuses are widely used in chemical, petrochemical, energy and other industries [1,2,3]
Separation areas shall be provided within the tray column apparatuses, which significantly increase the volume of apparatus, without being the main zone of interaction of gas-liquid flows
When distances between the drain cups, arranged at the same level, are equal to width of a drain cup, it provides stable, uniform gas flow, which leads to decrease in hydraulic resistance of the proposed jet-film contact device
Summary
Various heat-mass transfer processes and apparatuses are widely used in chemical, petrochemical, energy and other industries [1,2,3]. Efficiency of these processes is mainly determined by improvement of the used contact devices. Nozzle columns have an uneven distribution of liquid and gas phases in the cross section of working area, which significantly reduces the efficiency of heat-mass transfer processes. At high gas flow rates, there is a problem of liquid droplets entrainment that largely restricts the increase in efficiency of the current heat-mass transfer devices and can lead to the “choking” of the column
