I know that oil may be recovered from sludge experimentally by liquid extraction, freezing and thawing, or by froth flotation, but I’d like to know the commercial techniques used as i'm supposed to design a system of oil sludge recovery for my graduation project.
Does anyone know anything about this?

Thank you

Hello,
we design, manufacture and sell the S.R.S. (Sludge Recovery System). It's a system based on the C.O.W. method, i.e. an automated, mobile and modular, non-manned oil tank cleaning system.
