«Intensification of mass transfer processes in the purification of biogas from ballast impurities»

Abstract

One of the innovative areas of energy conservation is the use of biological energy, including
the production and use of biogas.
This not only provides alternative energy, but also solves environmental problems
associated with the utilization and processing of agricultural waste with the production of organic
fertilizers, increasing crop yields, renewal of soil fertility.
For efficient use in biogas power plants, ballast impurities, in particular carbon dioxide and
hydrogen sulphide, whose total biogas content may be up to 50%, need to be removed. Among the
known processes for the purification of biogas from hydrogen sulphide and carbon dioxide, the most promising, in my opinion, is the process of monoethanolamine aqueous solution chemical
absorption, which can be used at atmospheric pressure.
Existing designs of equipment for the biogas purification process by chemical absorption are
designed for large volumes of gas phase and cannot be used in agricultural biogas plants.
Therefore, it is relevant to study the mass transfer processes in new designs of absorbers
providing biogas treatment in bioenergy installations for the utilization of organic waste resulting
from the economic activities of agro-industrial enterprises.
