摘要： An apparatus and process are provided for depressurizing, cooling, and, optionally, moisturizing retorted oil shale produced in an oil shale retort operated at superatmospheric pressure. Hot retorted oil shale particles are gravitated from the retort and into an elongated, multichambered vessel. In the upper chambers of the vessel the particles are partially cooled by contact with a controlled flow of liquid water. The water, having been totally vaporized, is removed from the particles at a rate which prevents the substantial flow of gases between the vessel and the retort. In the lower chambers of the vessel, the particles are first stripped of entrained hydrocarbon gas by gravitating through a countercurrently flowing stream of stripping gas and then brought to ambient pressure by gravitating through a long, narrow seal leg. Optionally, the depressurized and partially cooled particles are then further cooled and moisturized by admixing with a controlled flow of liquid water.
