    Abstract: A process for cracking a hydrocarbon stream by: combusting fuel in a gas turbine in the presence of compressed air to produce a flue gas, wherein the flue gas drives a turbine to produce electricity in a coupled generator or work to power a coupled rotating equipment; (a) feeding a first portion of the flue gas to a heat exchanger; (b) feeding ambient air to the heat exchanger to be heated by the first portion of the flue gas to provide heated air; (c) feeding a furnace with fuel and a mixture of a second portion of the flue gas and the heated air obtained by step (c) and (d) cracking the hydrocarbon stream in the furnace.

    Abstract: A separation system for separating a feed stream comprising propylene and propane and a method for separating such feed stream. 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.
