摘要： A method for dedusting synthetic oil is disclosed. A feed of dust-laden synthetic oil is dissolved in a non-polar solvent of at least one alkane containing from 4 to 7 carbon atoms and aggregates of dust material are formed. The dissolved dust-laden synthetic oil is then gravitationally separated into a substantially dedusted stream in a dust-enriched stream including aggregates formed in the dissolution step. The dissolution and gravitational separation steps are conducted at a temperature and pressure greater than about 150.degree. F. and about ambient pressure and less than about the critical point temperature and pressure of the solvent and the aggregates provide acceptable settling and sludge compression rates. Methods for producing and dedusting oil from synthetic fuel stock are also disclosed.

摘要： A process is provided to dedust oil derived from solid hydrocarbon-containing material, such as oil shale, coal or tar sand in multi-stage desalters. In the process, water is dispersed into the oil before entering each desalter to form an emulsion. The desalter separates the emulsion into a stream of oil having a substantially lower concentration of dust and a dusty stream of water containing most of the dust. In one embodiment, the sludge-like dusty stream from the first desalter is combusted in a lift pipe and used as heat carrier material in the retort. In other embodiments, the dusty stream from the first desalter is centrifuged or filtered and thereafter heated in a dryer to remove residual oil and water from the stream before the stream is combusted in the lift pipe and used as heat carrier material in the retort and dryer. Effluent water from the second and third desalters as well as from the centrifuge or filter are recycled upstream and dispersed in the oil.
摘要翻译：提供了一种从多级脱盐器中的固体含烃材料，如油页岩，煤或焦油砂中衍生的除尘油。在此过程中，在进入每个脱盐器之前将水分散到油中以形成乳液。脱盐器将乳液分离成具有基本上较低浓度的粉尘和含有大部分粉尘的多尘的水流的油流。在一个实施例中，来自第一脱盐器的污泥状灰尘流在提升管中燃烧并用作蒸馏器中的热载体材料。在其他实施方案中，来自第一脱盐器的多尘的物流被离心或过滤，然后在干燥器中加热，以在流在提升管中燃烧之前从流中除去残留的油和水，并用作蒸煮和干燥器中的热载体材料。来自第二和第三脱盐器以及离心机或过滤器的流出水在上游再循环并分散在油中。
