Process for the removal of solids from an oil

摘要

A process for removing suspended solids, particularly difficultly filterable inorganic solids, from an oil obtained as a refinery process fraction from steam and catalytic cracking units, shale oil retorting process fraction, or from coal conversion processes by adding to the oil an agglomerating agent which is a polyelectrolyte, usefully a water-in-oil emulsion of a water-soluble polymer whereby said solids are clustered together into readily separable agglomerates.
