<p>A hydrocarbon conversion process for light olefin isomerization is disclosed. The feed stream is admixed with the overhead vapor stream of a fractionation column, which also acts as a feed stream drying column. The resultant admixture flows through an isomerization zone, and the isomerization zone effluent is partially condensed and passed into the overhead receiver of the column. Uncondensed vapor from the overhead receiver is recycled to the isomerization zone as a hydrogen recycle stream and liquid hydrocarbons withdrawn from the receiver are charged to the top of the fractionation column as the feed stream to the column.</p> |
