Lube Oil Blending Plant Process Flow Diagram -

| Unit | Primary Function | Typical Equipment | Key Input/Output Streams | |------|------------------|-------------------|---------------------------| | | Remove water, solids & salts | Desalting‑tank, deaerator, crude heater | Crude oil → Desalted crude | | 2. Base‑Oil Production | Convert crude into hydrotreated base oils (HBO) | Vacuum distillation column, hydrocracker, hydrotreater, dewaxers, solvent extraction, dewaxing unit | Desalted crude → Base‑oil fractions (e.g., API 30‑40, 40‑50, 50‑70) | | 3. Base‑Oil Storage | Buffer and quality‑check the fractions | Silos/closed‑top tanks, temperature control | Individual base‑oil streams | | 4. Additive Storage & Dosing | Store and meter performance additives (e.g., antioxidants, EP agents, viscosity modifiers) | Bulk additive tanks, metering pumps, gravimetric/volumetric dosing stations | Additive concentrate streams | | 5. Blending Section | Mix base oils & additives to meet product specs | Static mixers, dynamic mixers, high‑shear mixers, blending tanks, in‑line viscometers | Blending streams → Finished lube oil | | 6. Product Conditioning | Remove entrained air, adjust temperature, final quality checks | Vacuum deaerator, hot‑oil filter, cooling‑tower, storage tanks | Conditioned product | | 7. Finished‑Product Storage & Loading | Hold product until dispatch | Large insulated tanks, loading bays, metering/dispatch system | Product trucks/railcars |
