Deparaffinize – improving the cold flow properties of lubricating oils
Dewaxing is a refinery process in which waxes (kerosenes) are removed from lubricating oils. This process improves the low-temperature flow properties of engine oils, gear oils and industrial lubricants so that they retain their optimum viscosity even at low temperatures.
Why is Deparaffinize important?
Kerosenes in lubricating oils can solidify at low temperatures and impair the fluidity of the oil. This leads to:
– Better low-temperature properties for easier starting in winter
– Less oil thickening and higher pumpability
– Increased lubricant efficiency and reduced friction
BASINOL lubricants rely on advanced refined and hydrocracked base oils that are dewaxed to ensure consistent lubrication at any temperature.
How does Deparaffinize work?
During dewaxing, oils are cooled so that kerosenes crystallize. These waxes are then removed by filtration or solvent extraction to improve the fluidity of the oil.
Why are Deparaffinize oils important for winter engine oils?
Without this process, oils could thicken at low temperatures, leading to poor lubrication and starting problems. Dewaxed oils offer optimal cold starting properties.
Are there differences between deparaffinize and synthetic oils?
Yes! Synthetic oils naturally contain no waxes, whereas mineral base oils must first be dewaxed to make them suitable for winter use.
