  • Publication number: 20170174998
    Abstract: A technique for purifying solid materials containing contaminants, such as petroleum coke, may involve introducing the contaminated solid material into an extractor vessel along with an organic solvent. The contaminated solid material and organic solvent may be conveyed in a countercurrent direction during which the contaminant is extracted at least partially out of the solid material and into the solvent. After extraction, the resulting extracted solid material can be processed in a desolventizing unit and the recovered solvent sent back to the extractor. Further, the solvent containing extracted contaminant can be processed in a solvent recovery unit, further recovering solvent that can be sent back to the extractor.
