Abstract
A refinery slurry (1) containing water, oil and a solid fraction, is brought into contact with carbon dioxide gas (2) in order to adjust the pH value of said slurry at an acidic value and, in that way, improve the separation, by mechanical means, of a first water phase (4) and a first oil phase (5), from a sludge. The latter is submitted to an extraction with carbon dioxide, under supercritic conditions, in order to separate a second water phase (8) and a second oil phase from a residual sludge (9), which is disposed of. The process makes it possible most water, and, in particular, most oil contained in said slurry to be removed and a sludge to be disposed of, which shows a reduced propensity to the elution of the residual oil.
