Process for depropanizing benzene |
摘要 |
In the alkylation of benzene with propylene in a distillation column reactor to produce cumene the overheads from the distillation reactor are fed to a depropanizer where the unreacted benzene is separated from C3's. Liquid propylene feed for the distillation column reactor is vaporized by indirect heat exchange with the overheads from the depropanizer to condense the overheads, thereby reducing the pressure in the depropanizer below what would be normally achieved with conventional condensing systems.
