ABSTRACT:
A tar sand volatilizer system thermally removes petroleum crude oil from tar sands or shale oil. A series of heated augers or thermal screws are used to elevate material temperature gradually using conductive heat transfer. The thermal screws blades and auger case receive a heated fluid. The screws are driven by variable speed drive systems. The unit is sized for any throughput rate desired. Hot clean material discharges into a rotary cooler and re-hydrator unit. The exhaust gases are pulled through a high temperature filter collector for particulate removal. The particulate free petroleum vapor laden hot gas exits the filter house into a multi stage condenser system with water chillers where the vapor temperature is gradually cooled. A microwave upgrader system processes crude oil using catalyst injected microwave technology to produce a diesel like fuel oil in a continuous process stream.
