FIELD: oil and gas industry.
SUBSTANCE: method involves collecting volcanic gas, its cooling, and trapping the resulting compounds. The condensed compounds of rhenium and other elements are trapped from the volcanic gas cooled down to a temperature in the range of 150-250°C. Collective concentrate is trapped in a bag filter. In this case, the volcanic gas can be cooled in two stages, with successive use of cooling due to natural heat transfer and bringing the temperature of the volcanic gas to the controlled final temperature in the heat exchanger.
EFFECT: reduced energy consumption and simplified operation of equipment, increased extraction of rhenium compounds and other elements from volcanic gas.
