Product recovery method and system for hydrocarbon materials
A process and system are disclosed for producing and utilizing to advantage vapors and gases from hydrocarbon feedstock such as crushed oil shale, a coal and shale mixture, or straight coal. A prime mover driven by steam generated in the system produces electrical energy for supplying electrical power to the microwave oven employed. The prime mover is steam driven, such steam being supplied by a boiler. The boiler is, in turn, provided with a series of heat sources taking the form of the hot, spent shale, and/or coke from the coal, passing through such oven as well as perhaps portions of condensate or residue and portions or all of the gases generated in the system. The system thus reduces and in some cases may even eliminate power requirements otherwise imposed on an external electrical power source. Principally, however, the system generates sufficient energy as to be a m supplement to the energy requirement of an external power source. While magnetron tubes may preferably be employed in connection with the microwave oven used, other types of tubes or other electro-magnetic microwave generating means can be employed, this of a power requirement and wave length sufficient to heat the incoming feedstock. The feedstock itself is preheated by solids' hea exchangers, themselves raised in temperature by steam produced as well as the vapors and gases generated.
