Innovative Technology Solutions to Optimize Pulp & Paper Mill Operations

Decanter Centrifuge Technology (DCT) can significantly improve mill efficiency. Our proprietary technology can be custom engineered to provide two or three phase solutions, such as:

  • Soap separation from black liquor
  • Fiber removal from black liquor
  • Lignin removal from black liquor
  • Clean-up of soap, CTO, green liquor, wastewater

DCT is designed and manufactured in the USA, is reliable, low maintenance, has a small footprint (no need to redesign the mill or scale up for additional equipment), is energy efficient, and offers a range of higher throughputs.

Soap and CTO (Crude Tall Oil)

orange-line
Eliminate or improve skimmers, enhance soap recovery, separte solids from CTO, and potentially increase pulp production.
  • Eliminate or improve traditional soap skimmers
  • Improve soap recovery and increase CTO revenues
  • Separate solids, brine, and black liquor form CTO
  • Replace fiber vibration screens prior to CTO cleanup
  • Increase pulp production for recovery boiler limited mills
  • Increase softwood without adding skimmer capacity
  • Reduce fouling and other contamination of evaporators
  • Reducing downtime and maintenance
  • Small footprint as a standalone system or can run in parallel to soap skimmer for improved skimmers efficiency
  • Maintenance package and performance guarantee included
  • Manufactured and serviced in USA for over 37 years

Fiber and Solids

orange-line
Efficiently remove fibers from black liquor (recovered fibers), dewater and thicken materials, eliminate clarifiers, and significantly reduce waste disposal costs.
  • Efficiently separate fiber from black liquor – can handle fiber surges.
  • Robust and cost-effective dewatering and thickening solutions.
  • Can eliminate need for green liquor clarifiers and efficiently separate dregs.
  • Significantly reduces landfill and transportation costs by dewatering.
  • Streamline operations by eliminating clarifiers and Geotubes®
  • Low operational, service, energy, and maintenance costs
  • Environmentally friendly and significant cost savings by reducing landfill volumes (50% less water) and dredging/transportation costs.
  • More process flexibility

Lignin

orange-line
Our turn-key solution offers secure offtake agreements, immediate access to technology and markets, and participation in the downstream lignin market.
  • Turn-key integrated biomaterials solution for the P&P industry.
  • Secure lignin offtake prior to investment decision.
  • Have immediate access to technology, know-how, as well as global lignin markets, without adding resources or costs.
  • P&P Co. participates in the downstream lignin markets, not just selling lignin for BTU value.
  • Access to additional lignin converting technology as well as additional supply, including in different geographical regions.

Decanter Centrifuge Technology Pilot Trial Option

orange-line
Centrisys Renewables offers a pilot trial of our DCT for custom applications. The trial can help to determine equipment sizing and optimal locations. The trial typically includes:
  • Site survey for the trial and for a permanent location at the mill 
  • DCT skid on trailer for flexible installation options
  • Soft installation and operation of DCT by Centrisys/CNP
  • Lab sampling and testing during the trial, as necessary
  • Jointly review of trial results, best practices, and value proposition
Contact us for more information on our pilot trial options.
