FIELD: petroleum chemistry, chemical technology. ^ SUBSTANCE: fractionation is carried out in two columns. The parent raw is fed on the second column top, in line of its phlegm and isoprene fraction is removed from the second column top and fed its to the first column. Piperylene fraction is removed from the second column vat and isoprene is removed from the first column top, and isoprene-amylene faction is removed from this column vat that is fed for extractive fractionation. Invention provides reducing energy consumptions, enhancing quality of separation products and reducing their losses. ^ EFFECT: improved separating method. ^ 2 dwg, 6 tbl |
