Our thermal desorption system removes oil or solvents and waste from land banned wastes at refineries and chemical plants, as has recently been demonstrated at a large tank cleaning operation for an Illinois refinery. Waste is pumped into a centrifuge which separates the material into solid, oil, and water wastestreams.
Centrifuge cake is transferred into a dryer, where remaining oil and water are desorbed.
Dry powdery solids are discharged into pneumatic trailers, roll-off boxes or dump trailers. Desorbed vapors are scrubbed, condensed, and treated by carbon for minimal air emissions, and oil is recovered for reuse by both the centrifuge and the dryer. The system has been operated at a large tank cleaning project for an Illinois refinery, and at the Marathon refinery in Indianapolis, handling all oily sludges.
