Abstract: Devices, systems, and techniques can be provided for processing an oil-containing material with an alcohol-based solvent to extract oil from the material. In some examples, a system includes an extractor configured to process an oil-containing feedstock. The extractor receives the oil-containing feedstock and conveys the material from an inlet to an outlet through the extractor. The extractor also receives an alcohol-based solvent at a solvent inlet and conveys the solvent through the extractor to a solvent outlet. The resulting miscella formed by the extractor can be processed through multiple downstream processed steps to recover oil and solvent while reducing or eliminating processing challenges associated with fouling solids.

Abstract: The disclosure provides a process for a hydrothermal feedstock treatment including direct steam injection and cooling, which may be performed in the absence of a reactor. The process can be used to reduce inorganic and organic contaminants, such as salts, minerals, metals, asphaltenes, polymers, and coke precursors in both renewable and non-renewable feedstocks. The hydrothermal feedstock treatment may also be used in soap acidulation processes.
