mainly by traditional absorption and adsorption methods, as well as their various modifications. In
industry, especially oil and gas complex at various stages of extraction and processing, sulfur-
containing, so-called acidic (H

found in the aggregate, and their purification is carried out in a complex manner at the same
installations.
There are theoretically many methods for gas desulfurization. All of them have certain
advantages and a number of disadvantages [1-2].
Among the non-traditional methods of gas purification from hydrogen sulfide, an important
place is occupied by plasma technologies, the scope of which is expanding in various industries.
Scientific research is being carried out on the use of plasma in the oil and gas industry. Various
types of electrical discharges are investigated, with a large range of parameter values. The most
promising is the use of a streamer corona discharge, the possibilities of which for gas purification
from environmentally harmful impurities are being actively studied both in our country, and in
many countries of Europe, China, Japan, North America [3].
The prospects for the development of this method are determined by the expectation of its
high efficiency and environmental friendliness.
As part of this work, laboratory studies were carried out on the process of purification of
associated gases from hydrogen sulfide and their processing into elemental sulfur in electric corona
discharge, the form of which is a streamer. Streamers are narrow luminous branched channels
formed in the pre-breakdown stages of spark and corona discharges.
The use of a streamer corona for gas purification, in particular from hydrogen sulfide, is
based on the creation of active radicals and molecules, followed by removal which presents a
simpler problem. The potential of the streamer corona is considered both in the field of processing
of primary oil and gas raw materials, and in the field of waste disposal and synthesis of new types
of hydrocarbon fuels and raw materials for other petrochemical industries.
