FIELD: chemical industry; reduction of residual levels of solvents after extraction. SUBSTANCE: proposed plant includes extraction apparatus containing agent in liquid state which is contaminated with fluorine-and-hydrocarbon solvent and gas source for bubbling extracting agent of bio-mass with steam removing the solvent. Gas source includes rigid hollow adapter provided with hole exhaust of gas and connected with compressed steam source used for removal of solvent; steam used for removal of solvent flows from its source through hollow rigid adapter and escapes through gas exhaust hole. Gas exhaust hole immersed in liquid agent is used for bubbling of this agent by means of steam removing the solvent. Bubbling of liquid agent contaminated with fluorine-and-hydrocarbon solvent is performed by means of steam. EFFECT: enhanced efficiency; improved distribution of gas in agent. 4 cl, 5 dwg, 1 tbl, 1 ex
