FIELD: gas industry.
SUBSTANCE: group of inventions relates to processing of high-temperature volcanic gases. Method comprises increasing pressure of collected low pressure gas from the fumarole cracks and channels of volcano, then cooling to allow condensation of sulphide compounds scattered and rare elements, produced mixture is cooled to temperature higher than melting point of sulphur, mixed with sprayed liquid sulphur and cleaned with provision producing melt containing sulphur and solid and liquid uncondensed sulphide compounds scattered and rare elements and cooled purified volcanic gases. Melt is directed to extraction of scattered and rare elements, and cleaned volcanic gases heated hot crude volcanic gases and fed into atmosphere, compressed air heated in cooling volcanic gases is used for electric power generation. Also disclosed are a device and a method of processing gas from gas-filled part of volcanic channel or horizons, located below surface of volcano.
EFFECT: providing processing of volcanic gas with extraction of scattered and rare elements, power generation and maintenance of gas pressure in volcano to prevent eruption.
