Abstract
In the chemical industry, as well as in the petrochemical, construction, metallurgical, mining and chemical and
other industries, packed and tray columns are used for the mass transfer process. This paper provides a brief introduction
to packed columns and their applications. The principle of operation of movable nozzles is outlined, as well as
their main disadvantages. An experimental absorption column is described and a technique for conducting experimental
studies is described. Based on the results of the experiments, graphs of the dependence of the hydraulic resistance
of the support-distribution grids on the gas velocity, as well as movable ball nozzles using these grids, both
with and without irrigation, were plotted.
