In an olefins plant for the production and recovery of ethylene and propylene, the hydrogenation of the C2 acetylenes, the C3 acetylenes and dienes and the C4 and heavier acetylenes, dienes and olefins and the selective separation of the resulting products is carried out by the use of various arrangements (68, 78, 100, 118) of one or more reaction distillation columns. These columns contain a hydrogenation catalyst (70, 82, 102, 103, 104, 105, 116) in enriching (81) and stripping (83) sections and concurrently perform a catalytic hydrogenation reaction and a distillation function. |
