Syncrude dedusting extraction
This patent describes a method for dedusting synthetic oil. It comprises: substantially dissolving a feed comprising a dust-laden synthetic oil selected from the group consisting of shale oil, tar sands oil and tar sands bitumen in a non-polar solvent comprising at least one alkane containing from 4 to 7 carbon atoms and forming aggregates comprising dust material; and gravitationally separating the dissolved dust-laden synthetic oil into a substantially dedusted stream and a dust-enriched stream comprising aggregates. The aggregates provide acceptable settling and sludge compression rates; the dissolution and gravitational separation steps are conducted at a temperature and pressure greater than about 150{degrees} F. and about ambient pressure and less than about the critical point temperature and pressure of the solvent.
