Solvent extraction is a critical process in the production of high-quality base oil from waste oil. It involves using selective solvents to separate desirable lubricating oil fractions from impurities such as waxes, asphaltenes, and other contaminants. One of the most crucial factors influencing the efficiency and effectiveness of this process is temperature control. https://www.purepathtech.com/base-oil-solvent-extraction-plant
