METHOD OF PROCESSING HYDROCARBON FRACTION Russian patent published in 1999 - IPC

Abstract RU 2141935 C1

FIELD: rubber industry. SUBSTANCE: hydrocarbon fraction C3-C5 is isolated from process stream, condensed, and fed onto 25th plate of supplementary rectification column, from the top of which fraction C3 with concentration 90-98% is run off and from the bottom fraction C4-C5 with content principal components 98- 99% is withdrawn. Column is operated at pressure 1.45 MPa and temperature 105 C. Hydrocarbon fraction C3-C5, usually rejected into fuel system, is further processed to be separated into fractions C3 and C4-C5 used in cooling apparatuses and as motor fuel components. EFFECT: increased processing efficiency. 4 cl, 1 dwg, 1 tbl
