System for fuel and products of oil shale retort

Patent ·
OSTI ID:6552682
; ; ; ;
An underground room in substantially undisturbed shale is filled with fragmented oil-shale particles for in situ retorting. A comprehensive system is provided for feeding air to the top of the retort and recovering oil and flue gas from the bottom of the retort. The oil is separated from admixed water and both are recovered. Flue gas is withdrawn from the bottom of the retort, scrubbed clean, and a portion may be recycled through the retort while another portion is vented or burned in a turbine. Means also are provided for passing scrubbed gas through a second spent shale retort prior to venting, burning or recycle. (10 claims)
