METHOD OF VOLCANIC GAS PROCESSING WITH EXTRACTION OF RHENIUM COMPOUNDS Russian patent published in 2019 - IPC E21B43/00 E21B43/12 E21B43/263 C01G47/00 

FIELD: processing of volcanic gases.

SUBSTANCE: invention relates to processing volcanic gases and can be used in separating dispersed and rare elements from volcanic fumarolic gases. Method of volcanic gas processing with extraction of rhenium compounds includes connection of water with volcanic gas fumaroles by pumping water into small crater of volcano by cascade boost pumps from the nearest source of fresh water. Then, water is discharged into large crater in volume sufficient to prevent rapid evaporation of water in contact with high-temperature gas emissions of fumaroles. Reset is carried out by detonating separating crest volcano. Water with dissolved in it gas concentrate is lowered via discharge channel to receiving basin, which is located at the foot of volcano. Water discharged along the channel generates electric power generation by means of cascade hydroelectric power station. Solution of gas concentrate from the pool is supplied by the compressor for cleaning into the aerodynamic pipe and electric filter to produce the purified gas concentrate.

EFFECT: invention enables complex extraction of valuable components from volcanic gas, reduces material and labor costs, and additionally receives electric energy.
