FIELD: chemical industry; other industries; methods of withdrawal of fluorinated anionic surface-active substances from exhaust gases. ^ SUBSTANCE: invention is pertaining to the method of withdrawal of fluorinated anionic surface-active substances from the streams of exhaust gases, in which the gas stream bring in contact with the water solutions having in the range from 3.5 up to 13.8, in which concentration in the water solution of the fluorinated anionic surface-active substance withdrawn from the gas stream is less or equal to 70 ppm. The invention ensures high effectiveness of withdrawal of the fluorinated anionic surface-active substances from the gas streams - exceeding 99.0 % without presence of problems of pollution/sediments and without formation in the installation of such amount of the foam, which would influence on effectiveness of the production process. ^ EFFECT: invention ensures near hundred percent withdrawal of the fluorinated anionic surface-active substances from the gas streams without problems of pollution/sediments and without formation in the installation of such amount of the foam, which would influence on effectiveness of the production process. ^ 12 cl, 1 dwg, 1 tbl, 7 ex |
