Abstract
A system and process for recovering heat from a bitumen froth treatment plant use a sealed closed-loop heat transfer circuit. The system has a heat removal exchanger associated with the plant and receiving hot froth treatment process stream; heat recovery exchanger; the circuit; and an oil sands process fluid line. The circuit includes piping circulating heat exchange media having uncontaminated and low fouling properties. The piping includes a supply line to the heat removal exchanger and a return line for providing heated media to the recovery exchanger. The circuit has a pump for pressurizing the heat exchange media; a pressure regulator for regulating pressure of the media. The pump and the pressure maintain the media under pressure in liquid phase. The oil sands process fluid is heated producing a cooled media for reuse in the heat removal exchanger. High and low temperature heat removal exchangers can be used.
