Mineral oils and greases are fatty substances of various natures obtained from the distillation of petroleum, used in countless applications across a wide range of industries, including lubricant formulations in the industrial sector, cosmetics, and pharmaceuticals.
This is a process in which impurities such as oils, colorants, and aromatic compounds are removed through a demanding purification process involving hydrogenation at high pressure and temperature, followed by filtration using bleaching earths like Sepigel®, to achieve products suitable for their final use.
This involves the recycling of used oils, where additives, water, metals, and other sediments formed during the oil’s usage that affect its performance are removed through acid treatment, neutralization, and bleaching with bleaching earths like Sepigel®, which are separated from the regenerated oil by filtration.
Sepigel® has developed a complete range of bleaching earths, widely used in the bleaching and purification processes of mineral oils and greases, thanks to the excellent adsorbent properties of these clays.
The treatment with these earths results in purified oils and greases with greater stability and a longer life cycle, meeting the stringent specifications required in today’s markets for coatings, cosmetic products, personal hygiene, pharmaceuticals, or food.
Sepigel®, a wide range of products in constant development offering optimal solutions for different markets and applications related to the purification, refining and bleaching of oils and fats.
