Treatment and Recovery of Oil-Based Sludge Using Solvent

Solvent extraction was used to treat oil-based sludge from oil tankers. Methyl ethyl ketone (MEK) and LPG condensate were among the solvents used. Different solvent-to-waste ratios by weight were used to determine the optimum process. The mixture was then filtered, and solvent was recovered from the filtrate through distillation.

Solvent extraction method for oil sludge treatment

The process utilizes an extractant to dissolve the oily sludge. After being stirred and centrifuged, most of the organic matter and oil are extracted from the mud by the extractant; then the extract is recovered for distillation, the solvent is separated from the mixture for recycling, and the oil is used for refining.

Oil recovery from tank sludge - DigitalRefining

• In crude oil washing, crude oil is used as a ‘solvent’ for sludge. Here is a simple question: if crude is a solvent for the sludge, why has the sludge precipitated? Crude is not a solvent for the sludge and this method simply moves the sludge from one tank to another (a dispersion method). Integration with a physical separation method adds only the removal of sediments but, again, does
