The separation system includes a distillation column for producing a light stream comprising propylene and a heavy stream comprising propane; a reboiler for reboiling a part of the first heavy stream to produce a boiled heavy stream; a condenser for cooling the light stream to produce a condensed light stream; and an absorption refrigerator for receiving water and providing chilled water, for receiving hot water from a waste heat source and providing a cooled hot water and for receiving cooling water and providing a heated cooling water. The absorption refrigerator is arranged such that the cooling of the water and the hot water occurs by the cooling water. The condenser is arranged such that the cooling of the light stream occurs by the chilled water from the absorption refrigerator.
