Device and method for obtaining carbonic substances from oil sands

Abstract

A device for obtaining carbonic substances, particularly bitumen, from oil sands is provided. The device has at least one steam generator, an injection pipeline and a production pipeline. Steam can be introduced into the oil sand via the injection pipeline, and the carbonic substance can be removed from the oil sand via the production pipeline. At least one steam turbine is arranged between the steam generator and the injection pipeline. A method for obtaining carbonic substances, particularly bitumen, from oil sands is also provided.

1 . A device for extracting carbonaceous substances from oil sands, comprising
 at least one steam generator, an injection pipeline and a production pipeline, wherein steam can be introduced into the oil sand via the injection pipeline and the carbonaceous substances can be removed from the oil sand via the production pipeline,   wherein at least one steam turbine is arranged between the steam generator and the injection pipeline.   
     
     
         2 . The device as claimed in  claim 1 ,
 wherein the steam production is carried out by a heat exchanger, wherein hot exhaust gas of a heat engine or a directly fired boiler are used for steam production.   
     
     
         3 . A method for extracting carbonaceous substances from oil sands by a device as claimed in  claim 1 , comprising:
 producing steam in the steam generator;   feeding the steam to the steam turbine;   expanding the steam in the steam turbine to a steam pressure which is lower than, or equal to, the rock pressure;   introducing the steam via the injection pipeline into the oil sand;   heating the oil sand by the steam and breaking down the long-chain hydrocarbons of the carbonaceous substances; and   removing the carbonaceous substances via the production pipeline.   
     
     
         4 . The device as claimed in  claim 1 , wherein the carbonaceous substances comprise bitumen. 
     
     
         5 . The device as claimed in  claim 2 , wherein the heat engine comprises a gas turbine. 
     
     
         6 . The method as claimed in  claim 3 , wherein the carbonaceous substances comprise bitumen.
