Kaydon - Model 929-300 - Vacuum Dehydration Systems for Industrial Oils - Brochure

Model 929-300 is different than other dehydration processes as it takes water from the liquid state and transforms it into water vapor so it can easily be removed. In the distillation process, as water is vaporized from oil, oily water foam forms and is drawn into the vacuum pump. As the foam is transported through the condenser by the suction of the vacuum pump, the foam coats the inside of the condenser, reducing heat transfer. In addition, the oily foam releases through the system waste water discharge, requiring further wastewater treatment. Unlike other vacuum systems that do not provide effective foam control and must be constantly monitored,
