Used oil refinery plants process used oil through several steps: Collection and Transportation: Gathering used oil from various sources and transporting it to the refinery. Pretreatment: Removing impurities like water and sludge. Distillation: Heating the oil to separate it into different fractions. Hydrotreating and Dehydration: Removing contaminants to enhance product quality. Blending and Additive Addition: Ensuring the refined products meet industry standards. These plants utilize advanced technologies to efficiently recycle used oil, underscoring their importance in promoting energy security and sustainable resource management. https://www.purepathtech.com/lube-oil-refining-plant
