Recycled Fibres Pilot

A unique and essential tool for recycling and deinking

  • Prepare recycled or deinked pulp at semi-industrial scale
  • Test new types of paper to be recycled
  • Test new process configurations
  • Test new chemicals

The little story of the pilot

Following initial studies that began in 1974 regarding recycled fibres, in 1978 the CTP acquired the first components of its pilot facility representing real industry conditions. Since then, the pilot has been constantly updated to put it in a position to reproduce both up-dated industrial recycling and de-inking production lines.

The specific characteristics of this pilot include:

  • A low production rate (20 to 50 kg/h), to maintain control of the raw material to be recycled
  • A flexible configuration so that the different units can be interconnected, using conventional or more original setups
  • Possibility of re-using process water internally under continuous operating conditions in certain configurations.

Characteristics

Raw material that can be processed:

The recycled fibres pilot is capable of processing materials delivered in bulk or in the form of bales. Depending on the size of the paper/board to be recycled, a shredding stage can be implemented to ensure compatibility with the pilot facility.


Processes that can be simulated, and main characteristics :

  • Recycling lines for the production of packaging
  • Deinking lines for the production of deinked pulp for all types of use
  • Production at a rate between 20 and 50 kg/h

Main equipment items that can be connected:

  • Pulping:
    • Drum pulper with a diameter of 3 m
    • Helico pulper
    • Low consistency pulper
  • Coarse screening:
    • Hélipoire or rotary-drum screen with holes of diameter 6 mm
    • HD cleaner to eliminate heavy particles such as glass, sand, staples, etc.
  • Fine screening in a CH3 pressure screen
    • Basket with slots of width 0.10, 0.20 or 0.35 mm
    • Basket with holes of diameter 0.25, 0.50, 0.80 and 1.2 mm
  • Centrifugal cleaning
    • More than a dozen hydrocyclones to eliminate heavy or light contaminants
  • Flotation cells
    • 4 Verticells
    • 1 Mak-C cell
    • 1 column flotation cell
    • 1 secondary Verticell
  • Washing
    • A Classiflux washer
    • 2 Baker inclined screws
  • Thickening
    • 2 Vernay vacuum filters
    • 2 screw presses
  • Dispersing with the possibility to inject steam and chemicals
    • High-speed disperser
    • Low-speed kneader
  • Others:
    • Connection possible with the cleaning / fractionation pilot
    • Connection possible with the bleaching pilot.
