Abstract
A method for separating oleaginous material from an aqueous medium is provided. An oil-containing aqueous medium is contacted with an oil-sorbing matrix prepared by subjecting a feedstock to conditions which alter its physical and chemical structure to provide a hydrophobic oil hog. The feedstock includes a hydrophobic matrix having oleaginous-imbibition capability in an oil-hog-altered physical state.
Claims19
A method of separating an oleaginous substance from an aqueous medium, comprising:
- contacting an oleaginous-containing aqueous medium with an oil-sorbing matrix including an oil sorbent prepared by subjecting a feedstock comprising a hydrophobic material which has oleaginous-imbibition capability in an altered physical and chemical state to flash flow conditions which alter the physical and chemical structure of said feedstock to provide said altered physical and chemical state, whereby said matrix separates said oleaginous substance from said aqueous medium;
- wherein said flash flow conditions comprise simultaneously subjecting said feedstock to conditions of flash heating and applied physical force or flash force and applied heat.
