High-capacity system for recovering entrained oil, water
M-I SWACO offers Rotary Kiln Thermal Desorption Technology to recover entrained water and oil from contaminated cuttings. This widely accepted technique uses a rotating, inclined cylinder to process waste cuttings.
The M-I SWACO Rotary Kiln process moves contaminated material to a feed auger that delivers it into the kiln. The material is indirectly heated, increasing the temperature and resulting in desorption of the oil and water. The oil and water vapors are removed from the kiln and quickly condensed for oil and water separation and recovery. The oil-free treated solids are then cooled and rehydrated in an enclosed discharge auger while being conveyed away from the unit for disposal onsite or offsite.
Our process is based on an indirect fired method in which all heat being transferred to the processed material is conducted to and radiated through the kiln shell.
