Apparatus and method for supplying continuous heat/pressure to continuously feed and discharge heated/pressurized oil shale sludge in kerogen extraction reactor

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.
