The Three Phase Decanter Centrifuge for Pyrolysis Oil Sludge Separation continuously separates recoverable pyrolysis oil, water, and carbon-rich solids from conditioned sludge.

It is suitable for suitable waste-plastic, tyre, and mixed-waste pyrolysis streams containing oil, free water, char, recovered carbon black, ash, rust, and catalyst fines. Pyrolysis-oil properties can vary significantly in viscosity, water content, stability, and contaminant loading, so feed testing is required before final selection.

• Pyrolysis oil pretreatment before filtration
• Carbon-fines concentration
• Sludge-volume reduction

Fine Char and Carbon Black

Fine char, carbon black, ash, and catalyst particles may remain suspended in the oil.

High centrifugal force and stable feeding help recover these solids. Polishing filtration may still be required when very low solids content is needed.

High Viscosity and Tar

Heavy hydrocarbons, waxes, and tar-like components may reduce pumpability and separation efficiency.

Controlled heating can reduce viscosity and improve feeding, but the temperature must remain within the process and safety limits.

Oil-Water Emulsions

Fine solids and process chemicals may stabilize the oil-water interface.

Heating, settling, dilution, or demulsifier dosing may be needed before centrifugation.

Abrasive and Sticky Solids

Carbon particles, ash, sand, and metal fines can cause wear, while tar may create deposits.

Carbide tiles, ceramic liners, replaceable discharge inserts, and automatic flushing can be provided.

Variable Oil Composition

Pyrolysis oil quality changes with feedstock, reactor conditions, condensation temperature, and storage time. Adjustable bowl speed, differential speed, feed rate, and phase interface help accommodate changing conditions.

Peony provides three-phase separation for oil recovery, water removal, and carbon-solids concentration.

Pyrolysis Oil Recovery

Recovers hydrocarbon-rich liquid from sludge before solids disposal or downstream purification.

Carbon-Fines Removal

Separates char, carbon black, ash, and other suspended particles that may foul filters and downstream equipment.

Separate Water Removal

Removes free and separable water before oil filtration, distillation, or upgrading.

Heavy-Duty Wear Protection

Protected feed, scroll, cone, and solids-outlet areas support abrasive carbon-rich sludge.

Flexible Feed Adjustment

The phase interface and operating speeds can be adjusted for changing oil, water, and solids ratios.

Please provide:

• Pyrolysis feedstock type
• Oil, water, and solids percentages
• Temperature and viscosity
• Particle size and solids composition
• Required capacity and oil quality
• Downstream purification process
