DEVICE AND METHOD FOR EXTRACTING CARBON-CONTAINING SUBSTANCES FROM OIL SAND

摘要

The invention relates to a device for extracting carbon-containing substances, in particular bitumen, from oil sands. The device comprises two separate steam circuits. The first steam circuit is a closed steam circuit, in which a steam turbine is operating. The second steam circuit is an open steam circuit and is used for extracting carbon-containing substances, in particular bitumen, from oil sands. The steam turbine comprises an intermediate steam removal facility, wherein the intermediate steam is used to evaporate the water/vapor in the second steam circuit via a heat exchanger. The invention further relates to a method for extracting carbon-containing substances by means of the previously described device.
