Advanced plants use PLC-controlled flow meters or load cells to ensure precise, automated dosing of components according to the formulation, reducing human error and waste. 3. Blending and Homogenization

Raw base oils arrive via vessel, railcar, or tank truck and pass through dedicated unloading manifolds.

Based on the final lube oil recipe, the required volumes of base oil and additives are transferred to the blending unit. The PFD includes symbols representing the blending technology chosen—ABB, ILB, or SMB—and the pipelines from each storage tank to the blending unit.

High-shear mixers or agitators ensure the additives are completely dispersed in the base oil to form a homogeneous mixture.

The oil rests to release entrained air before moving to the automated packaging lines. Key Utility Systems Supporting the PFD

Before moving to the filling line, a sample is sent to the lab. Key parameters tested include Kinematic Viscosity, Flash Point, Total Base Number (TBN), and appearance. 4. Storage of Finished Products

Advanced LOBPs use "pigging" technology—where a solid plug (pig) is blasted through pipes using compressed air to push out leftover oil. Look for pig launchers and receivers on the PFD; these minimize cross-contamination between different oil batches.
