The Industrial Decanter Centrifuge for Solvent-Containing Slurry continuously separates suspended solids from solvent-bearing process liquids.

It is suitable for chemical, pharmaceutical, battery-material, fine-chemical, and solvent-recovery processes requiring closed and controlled separation.

• NMP-containing battery-material slurry
• Ethanol or methanol extraction residues
• ketone process slurry
• DMSO, THF, or mixed-solvent residues
• Catalyst and activated-carbon recovery
• Resin and polymer production sludge
• Fine-chemical reaction slurry
• Pretreatment before solvent distillation

Flammable Solvent Vapors

Volatile solvents may create hazardous vapors.

Gas-tight construction, inert-gas protection, and explosion-proof components can be provided.

Solvent-Compatible Materials

Solvents may affect seals, gaskets, coatings, and lubricants.

Material compatibility must be confirmed before equipment selection.

Fine Suspended Solids

Catalyst fines, carbon particles, polymers, and crystals may settle slowly.

Bowl speed and residence time must be matched to the particle characteristics.

Product and Solvent Loss

Open handling may cause evaporation, odor, and valuable solvent loss.

A closed separation system helps reduce vapor release.

Sticky or Abrasive Solids

Resinous deposits or catalyst particles may cause buildup and wear.

Automatic flushing and wear protection can be configured.

Solvent-Containing Slurry
→ Closed Feed Tank
→ Controlled Feed Pump
→ Gas-Tight Decanter Centrifuge
→ Solvent-Bearing Liquid + Concentrated Solids

Solvent-Bearing Liquid → Distillation / Reuse / Further Treatment
Concentrated Solids → Recovery / Drying / Disposal

Peony Can Provide

• Slurry testing and centrifuge selection
• Closed feed tank and controlled pump
• Gas-tight centrifuge configuration
• Nitrogen inerting system
• Explosion-proof motor and instruments
• Solvent-compatible seals and materials
• PLC and dual-VFD control
• Automatic flushing and vapor collection

Reduced Solvent Loss

Closed feeding and discharge help limit evaporation and solvent emissions.

Safer Solvent Processing

Gas-tight construction, inerting, and explosion-proof options support flammable applications.

Improved Solvent Recovery

Removes suspended solids before distillation, purification, or process reuse.

Solvent-Compatible Configuration

Seals, wetted materials, and instruments are selected according to the solvent composition.

Continuous Solids Removal

Catalysts, carbon fines, crystals, and process residues discharge without batch filtration cycles.

Please provide:

• Solvent type and concentration
• Flash point and operating temperature
• Solids content and particle size
• Flow rate and viscosity
• Required liquid clarity
• Hazardous-area requirements
