Base Oils (mineral/synthetic), Additive Packages.
Here is a simple process flow diagram:
The process flow diagram should highlight the key equipment and instruments used in the plant, including:
Once cleared, the oil is pumped to automated filling stations. The PFD will show streams branching into various packaging configurations: Small packs (1-liter to 5-liter bottles) Pails (20-liter) Drums (200-liter) Bulk loading arms (for tank trucks) Typical Equipment Symbols Found on an LOBP PFD lube oil blending plant process flow diagram pdf
These are usually received in bulk via pipelines, tank trucks, or rail cars and stored in large vertical tanks.
Base oils make up 70% to 90% of the finished lubricant volume.

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
Reserved for massive, continuous production runs of high-demand oils (e.g., standard 15W-40 or 5W-30 motor oils). 4. Vessel Homogenization and De-aeration

Powerful agitators or mixers churn the liquid, creating a homogeneous blend that won't separate over time. 4. The Validation: Quality Control
The diagram indicates automated temperature loops. These loops maintain base oils between 35°C and 45°C, while additive tanks are kept warmer (up to 60°C) to prevent chemical stratification or settling.
Reduced human intervention minimizes exposure to chemical additives.
