ABSTRACT:
An in situ oil shale retort is provided with a sealed space at the bottom in which liquids produced in the in situ retort and retort off gases are separated. The separated liquids and retort off gases are removed from the sealed space through a bulkhead provided in an access tunnel leading to the sealed space which can be a portion of the tunnel. A sump is provided in the floor of the access tunnel inside the sealed space for collecting liquids. Trenches extending from the bottom of the in situ retort into the sump are provided for directing liquids from the in situ retort to the sump. The trenches are backfilled with large shale particles to prevent blocking of the trenches when the oil shale in the retort is explosively fragmented. Conduits extending through the bulkhead and into the sealed space are provided for removing liquids from the sump and retort off gases from the sealed space above the liquid level.
