Abstract
The object of research: mass transfer processes on a combined contact element in a column apparatus.
 Investigated problem: determination of the regularities of process parameters in the processing of gas-liquid systems in a foam layer, as well as to interpret the obtained experimental data. The problem of processing industrial gas flows is solved by conducting the process in an intensive mode.
 The main scientific results: as a result of the study, the regularities of ammonia absorption were revealed depending on the main parameters of the experiment: gas velocity in the column cross-section, ammonia concentration, free cross-section of the combined contact element, and liquid loads. The process of mass transfer in the gas phase is significantly influenced by hydrodynamic parameters – the gas velocity in the apparatus and the specific load on the liquid, which indirectly affect the height of the liquid layer on the plate and the gas content of the layer.
 The area of practical use of the research results: sorption processes for processing gases and liquids in technological processes, absorption of harmful substances in the treatment of gas emissions.
 Innovative technological product: new block poppet-nozzle contact device that operates in a stabilized hydrodynamic mode; new ball-shaped weighted nozzle for three-phase foam layer.
 Scope of application the innovative technological product: technological processes in the treatment of gas emissions or technological gases.
Highlights
When studying the absorption of ammonia (Fig. 2) it was found that the efficiency of the device somewhat depends on the change in the gas velocity
It can be observed that the efficiency with the use of a stabilizer is greater than without it and is noticeably greater when using a stabilizer with a plate with a smaller free cross-section and with plate holes de= 0.012 m
This can be explained by the fact that plates with a larger free cross-section contribute to a larger liquid failure, and sufficiently large holes and a moderately low free cross-section create a greater height of the foam layer, and the mass transfer surface increases
Summary
The object of research The object of research is mass transfer processes on a combined contact element in a column apparatus. Problem description In conditions of significant anthropogenic pressure on the environment the investigation for the most effective and economical methods of cleaning industrial emissions is relevant. Cleaning methods and equipment developed should take into account the possibility of working in a wide range of operating conditions. To reduce energy consumption in systems for capturing harmful and toxic substances, it is necessary to reduce hydraulic resistance while maintaining high efficiency in cleaning gas flows. Given the contradictory requirements for equipment and despite the large number of existing devices for mass transfer processes, the development of new high-intensity and efficient equipment is of considerable interest to environmental technologies in many industries [1]
