Description

Oily sludges are hazardous wastes that contain large amounts of hydrocarbons, water and dissolved solids. A simple distillation procedure was used to fractionate this sludge and isolate a gas phase (10%), and an organic liquid phase (30%) that can be used as fuels. This procedure also separates the water phase from the dissolved solids enabling the independent management of those phases with more appropriated methods
