Base oil is one of the most important components in many lubricants, providing the foundation for products used in automotive, industrial, and mechanical applications. However, the performance of base oil can be affected by naturally occurring wax molecules. When temperatures fall, these waxes can crystallize and reduce the oil's ability to flow.
Base oil dewaxing is therefore an important refining process used to improve low-temperature performance and produce oils with a lower pour point.
