摘要
Processes for providing an isobutane recycle stream to be recycled to a dehydrogenation zone. In some embodiments a dividing wall column is used to separate a hydrogenation effluent. The hydrogenation effluent may include olefins, or it may be fully saturated. A hydrogenation zone may include a nickel based catalyst and may fully saturate dienes and olefins, or only hydrogenate dienes.
