Patent ·
OSTI ID:6468846
This patent describes a system for treating sludges containing relatively heavy hydrocarbon liquid and solids which are coated with the hydrocarbon liquid. It comprises: a combustion unit for combusting hydrocarbons to provide gaseous combustion products and a substantially hydrocarbon free, friable solids mixture; a source of solids material having a particle size which averages about one inch or less and having a relatively high liquid adsorption capability; means for mixing the sludge with the solids material and for conveying a mixture of the solids material and the sludge comprising a flowable and friable solids mixture to the combustion unit; means for receiving a friable, hydrocarbon free solids mixture from the combustion unit for disposal; means for receiving gaseous combustion products from the combustion unit and for condensing at least part of the gaseous combustion products; and means for conveying a mixture of condensed combustion products and solids fines to the combustion unit.
