Abstract
In an olefins plant for the production and recovery of ethylene and propylene, the hydrogenation of the C.sub.2 acetylenes, the C.sub.3 acetylenes and dienes and the C.sub.4 and heavier acetylenes, dienes and olefins and the selective separation of the resulting products is carried out by the use of various arrangements of one or more reaction distillation columns. These columns contain a hydrogenation catalyst in enriching and stripping sections and concurrently perform a catalytic hydrogenation reaction and a distillation function.
