: The mixture is heated (often using a thermic fluid heater) to reduce viscosity and ensure additives dissolve effectively. Agitators or high-shear mixers create a uniform, homogeneous blend.
: Base oils (mineral or synthetic) and additives are stored in specialized tanks. Large storage tanks often hold base oils like SN150 or SN500, while smaller units manage additives. lube oil blending plant process flow diagram pdf
: Approved oil passes through fine micro-filters (e.g., 2-149 microns) to remove particulate matter before being filled into bottles, drums, or bulk tankers. LINUS PROJECTS (INDIA) LUBE OIL BLENDING PLANT | LINUS PROJECTS (INDIA) : The mixture is heated (often using a
: Additives are often transferred from drums using a Drum Decanting Unit (DDU). Components are metered or weighed precisely—using flow meters for liquids and load cells for bulk components—before entering the blending vessel. Large storage tanks often hold base oils like
The typical process flow moves from raw material storage to final packaging through several critical stages:
