LAMINATION OIL RECOVERY SYSTEMS

Mid-sized and large cold rolling mills utilize lamination oil with lubricant and cooling purpose while processing the metal strip. Large volumes of cold rolling oil are continuously injected: part of the lamination oil is kept by the rolling mill ventilation system in form of vapor or liquid mist and such oil needs to be captured and treated to avoid the emission in the atmosphere.
airprotech system provides a double action in one single plant
• oil mist emission control
• lamination oil recovery 
The system combines the treatment of exhaust air loaded with oil mist from aluminum foil rolling mills with the recovery of the lubrication oil itself to be reused in the process with considerable economic return instead of replacing the lamination oil with brand new product.
Lamination oil in form of vapor or liquid mist is treated by a scrubber and is combined with a cleaning oil, the resulting product is then passed to a distillation column for separation. The lamination oil recovered is finally finished and reused in the customer process, the cleaning oil is reused again in the scrubber.
