Abstract—Results of experimental studying hydrodynamic resistance and interplate entrainment of a plate
deflector with a perforated plate are presented. The diapason of operational stability of the perforated plate with
a plate deflector was determined. Analytical dependences for the calculation of the hydrodynamic resistance and
the interplate entrainment were obtained.
It is known that entrainment of liquid drops by
a gas (vapor) ﬂ ow from contact plates of mass-transfer
apparatus results in essential depression of driving
force of transport processes. Therefore interplate
entrainment is one of the major factors limiting rise of
gas (vapor) rate in mass-transfer apparatus. To reduce
drop entrainment at raised gas loads, it is necessary
to increase either a column diameter or an interplate
distance, i.e. the overall apparatus size, that obviously
results in increasing general and energy expenditures.
To reduce drop entrainment without essential increase
in the interplate distances, entrainment separators of
various constructions are placed above a mass-transfer
