Patent ID: 10131846

Abstract:
The present invention relates to an improvement over the invention previously submitted by the inventor relating to an apparatus for recovering heavy oil from oil shale and a method for recovery using same, the present invention relating to an apparatus for supplying continuous heat/pressure to continuously supply and discharge oil shale sludge, in which a plurality of unit extraction apparatuses, comprising a kerogen extraction apparatus and an intermediate storage tank, are installed to implement a continuous operation, which is an improvement over a semi-continuous operation of alternately operating the kerogen extraction apparatus and the intermediate storage tank. According to the present invention, the kerogen extraction apparatus can be continuously operated as sludge in a pressurized state can be continuously supplied by disposing a pressurized supply pump for sludge in between the continuous mixing apparatus for oil shale/extractant and the kerogen extraction apparatus, and a pressure-controlling discharging valve on the exit side thereof, and as the oil shale and extractant/light oil added into the continuous oil shale/extractant mixing apparatus are maintained in the preliminary previously-heated state, the energy load of the kerogen extraction apparatus, for heating the thermal medium of the oil shale/extractant continuous mixing apparatus, can be reduced as the load can be shared with the continuous mixing apparatus, and thus has the benefit of reducing expenses due to a reduction in the size of the reactor and the ease of scaling-up.
