Recovery of liquid and gaseous products from an in situ oil shale retort
Patent
·
OSTI ID:6552883
An in situ oil-shale retort is provided with a retort off gas cooling zone in the retort at the product outlet end. The kerogen in the retort is converted to liquid and gaseous products by moving a heated gas through a retorting zone and toward the product outlet end. The movement of gas through the retorting zone is terminated when the retort off gas moving from the product outlet end attains a temperature above which the temperature of the off gases will deleteriously effect production collection and removal apparatus in a collection zone adjacent to the product outlet end. A reduced kerogen content of the oil shale in the retort off gas cooling zone as compared with the average kerogen content of oil shale in the retort improves the yield of products. (21 claims)
