Abstract

Изобретение предназначено для очистки тяжелой фракции сланцевого масла, использованной при очистке, полученной в результате переработки сланца с твердым теплоносителем парогазовой смеси, от накопившихся в ней твердых примесей. Для этого из подлежащей очистке тяжелой фракции, сланцевого бензина и фенольной воды готовят очищаемую смесь, которую при необходимости обрабатывают флокулянтом и которую затем в центрифугальном декантере разделяют на водную фракцию, твердую фракцию и органическую фракцию. Водную фракцию направляют обратно в процесс приготовления очищаемой смеси, твердую фракцию направляют в процесс пиролиза, органическую фракцию разделяют в колонне дистилляции на сланцевый бензин и чистую тяжелую фракцию сланцевого масла.The invention is intended for the purification of the heavy fraction of shale oil used in the purification resulting from the processing of shale with a solid coolant vapor-gas mixture from the solid impurities accumulated in it. To do this, a mixture to be cleaned from the heavy fraction, shale gas and phenolic water is prepared, which is treated with flocculant if necessary and then separated into an aqueous fraction, solid fraction and organic fraction in a centrifugal decanter. The aqueous fraction is sent back to the process of preparing the mixture to be purified, the solid fraction is sent to the pyrolysis process, the organic fraction is separated in the distillation column into shale gasoline and the pure heavy fraction of shale oil.
