Shale retorting process
Patent
·
OSTI ID:6042529
This is an eduction process for the retorting of oil shale to recover optimum oil and gas. Eduction is accomplished by recycling a pre-heated portion of the rich product shale gas to a solids-upflow, fluid-downflow retort. The eduction fluid is indirectly heated to retorting temperatures and is maintained essentially oxygen-free throughout the process. More specifically, in the eduction zone of the retort, conditions such as recycle education fluid volume, temperature, composition, and the like, are correlated and independently controlled for best overall results.
