Abstract
A process for removing the oil and water from the sludge, which consists in mixing said sludge with a light hydrocarbon whose specific weight is substantially lower than said sludge; separating the resulting mixture in water with a reduced chemical oxygen demand, a solids-water phase and an oil-hydrocarbon phase, heating the above mentioned phase to a temperature above the critical temperature of said hydrocarbon, under a pressure sufficient to maintain said hydrocarbon in dense phase, whereby said phase is separated into a hydrocarbon portion and a portion of oil and recover this latter portion.
