Increase of the mass transfer rate across a phase boundary in a plate column with moving bed elements

(OTKA T 037498)

There are numerous unit operations in the field of chemical engineering (such as absorption, desorption, scrubbing, distillation, etc.) which can only be carried out if gas (vapour) / liquid contacting is applied. The principal dimension of the operating equipment depends on the diffusion rate. The application of three – phase, fluid disperse systems yield much better results than the use of traditional fixed bed or plate columns.

The aim of the research work to determine of the three-phase fluid disperse column hydrodynamical characteristics: pressure drop values, liquid hold-up, porosity of the bed, etc.

Determination of the three-phase, fluid disperse columns mass transfer characteristics: height of transfer unit (gas side and liquid side).

Working up of the design method for the application of fluid disperse columns.
