Dewaxing of oil is a process of eliminating higher melting point constituents like waxes or triglycerides from oil by gradually cooling vegetable oils and separating saturated glycerides from the oil.
Normally Dewaxing process is carried out at higher temperatures (18-20 °C) to avoid the crystallization of saturated triglycerides & amalgamation of waxes & saturated triglycerides.
Waxes & Saturated triglycerides which are fairly visible at low temperatures are removed in this process to keep the appearance of oil clean transform Degummed, Bleached & Dewaxed oil is cooled and filtered to achieve the quality.
This process involves removing waxes and other impurities from crude oil or petroleum products to enhance their properties. Here are some advantages of the dewaxing or winterization process in the refinery:
Overall, the dewaxing process in refinery is a cost-effective way to improve the quality of petroleum products and increase profitability. Its benefits make it an essential step in the production of high-quality diesel, base oils, and lubricants.
Here are some essential steps to consider during the dewaxing or winterization process:
Overall, the dewaxing process in refinery is a critical step in producing high-quality vegetable oils. The process ensures that the oils remain liquid at low temperatures and can be used in various food applications.
