FIELD: petrochemical processes. SUBSTANCE: hydrogenation of C2-acetylenes, C3-acethylenes, C4-dienes, and heavier acetylenes, dienes, and olefins is conducted on olefin-production installation designed for ethylene and propylene isolation. Selective isolation of hydrogenation products is accomplished on one or several different-structure reaction-rectification columns containing hydrogenation catalyst in concentration and stripping sections, wherein dehydrogenation reaction and distillation take place simultaneously. EFFECT: simplified process. 13 cl, 10 dwg
