Abstract

Apparatus and methods for recovering hydrocarbonaceous and additional products from nonrubilized oil shale and oil/tar sands. One or more initial condensation steps are performed to recover crude-oil products from the effluent gas, followed by one or more subsequent condensation steps to recover additional, non-crude-oil products. At least a portion of the exhaust gas from a combustor may be routed through a heat exchanger to produce the processing gas, the composition of which may be adjusted so that it contains approximately 1% oxygen or less. The subsequent condensation steps may be carried out in at least one cooled chamber having a sequence of critical orifices maintained at a negative pressure. Carbon sequestration steps may be performed wherein recovered carbon dioxide is delivered down the hole following the recovery of the hydrocarbonaceous products. Various physical parameters may be adjusted to vary the recovery of crude oil or other products or contaminants from the effluent gas.
