Method and apparatus for recovering oil from oil shale without environmental impacts

摘要

The present invention relates to a method and apparatus for extracting kerogen oil from oil shale without adverse environmental impacts. A first plasma reactor is employed for creating a syngas from a carbon-based fuel. A turbine uses the syngas to produce electricity after the syngas' sensible heat passes through a heat exchanger to heat recycling gases used to pyrolyze the oil shale. A kiln receives the oil shale and heats the oil shale to a temperature at which hydrocarbons from the oil shale are released and captured. The hydrocarbons are sent to a distillation tower to produce a usable fuel. A second plasma reactor vitrifies the spent shale to produce an environmentally inert byproduct. The second plasma reactor is powered by electricity produced by the syngas turbine. Carbon dioxide generated by the process is captured and stored to prevent its release into the environment.
