The Origin: Crude Oil and Primary Distillation The journey of mineral oil begins deep underground, where ancient organic matter has transformed into crude oil. In pharmaceutical and food-grade mineral oils, these additives are strictly limited and must be approved for safety.
Solvent Extraction Method for Refining Mineral Oil Base Oil
The first critical step in creating mineral oil is the primary distillation of crude oil in a refinery. Because of this composition, it does not react readily with other substances, making it an ideal base fluid.
For specific applications, manufacturers add performance-enhancing additives to the base oil. Understanding what mineral oil is made of requires a journey from the depths of the earth to the precision of a laboratory distillation column, where complex crude fractions are transformed into a stable, inert material valued for its exceptional purity and lubricating properties.
Solvent Extraction Method for Purifying Mineral Oil
Bleaching: Passes the oil through bleaching clays to adsorb any remaining color compounds and trace metals. It contains impurities such as waxes, nitrogen compounds, and trace metals that must be removed.
