FIELD: chemistry.
SUBSTANCE: invention concerns to methods of removal of acidic gases from gaseous raw material with use of a solvent and can be used in chemical, petroleum-gas-reprocessing and other industries. The initial gaseous raw material 113 is submitted to an absorber 110 installation 100 for obtaining inert gas 114. The obtained enriched solvent 116 results in contact with the recycled gas 132D in the lower part of the absorber 110 with the obtaining of additional enriched solvent 116' The additionally enriched solvent 116' is subjected to instantaneous evaporation for obtaining the enriched solvent after instantaneous evaporation 134D and recycled gas 132D.
EFFECT: invention makes it possible increase the load on the solvent and to provide optimum conditions for desorption.
