Chilling Dewaxing Unit

Freeze dewaxing equipment separates wax from oil by cooling the oil below the temperature at which wax crystals form. The oil is passed through a freezing system to lower its temperature and induce wax crystallization. Solid wax is then separated from the oil using filtration or centrifugation.

This method is commonly used to produce low pour point lubricants and diesel, enhancing their flow and performance in cold environments. Unlike hydrogen dewaxing, freeze dewaxing does not involve hydrogen treatment, making the operation conditions milder and the equipment simpler.
