PPGT-BE Solvent Extraction Plant is designed to remove the undesirable ingredients such as PAHs, gums, asphaltenes, sulfur compounds, nitrogen compounds, oxygen compounds from the base oil. PurePath engineers team has redesigned the whole extraction process and applied multistages of centrifugal extraction system which is especially targeting for base oil produced from waste oil refinery to improve the viscosity index, oxidation stability, carbon residue, color of the base oil. With our exclusive solvent extraction and recovery technologies & innovations, you'll able to obtain over 98% of group 1+ base oil with only 1KG of solvent.
In the meanwhile, the resulting base stocks are raffinates (referred to as neutral oils) and an extract fluid that is rich in aromatic content, which is highly sought after as process oils and fuel oils.
