ABSTRACT:
A process for improving the separation of a hydrocarbon mixture is provided in which the hydrocarbon mixture is separated into fractions in a distillation zone. A liquid fraction and a portion of the vapor phase fraction are removed from the distillation zone as sidestream and introduced into a separation zone comprising a stripping gas to be stripped simultaneously. The resulting stripped vapor is recycled to an upper portion of the distillation zone.
