Energy Management

 

Century Pulp & Paper takes every effort to reduce its carbon footprint and impact to the environment.
This is achieved by constantly making improvements to its operations in the four key areas :

  • Power Consumption
  • Waste Management
  • Usage of Raw Materials and Conservation.

 

Power Consumption:

The plant consumes approximately 14.0 lacs units per day, of which an estimated 95% of power is generated internally. Of this, 45% of CPP's power needs are met through the process of biomass waste in the form of black liquor, pith and sawdust.

Other Initiatives for conservation of energy include:

  • Use or RGP hot water in bagasse pulp mill
  • Elimination of excess bagasse conveyor of a depither plant
  • Addition of a 2500 KVAR new capacitor in circuit to maintain plant power factor
  • Interlocking of deflaker motor with broke tower pump
  • Installation of DOCC mud filters to increase dryness of lime mud cake
  • Power saving through the replacement of existing gear boxes of chip screens, bifer screen and dewatering screw conveyor with helical gear boxes
  • Interlocking of supply pump and agitator of paper machine
  • Installation of heat exchanger in WPP pulp mill to recover heat from ash steam
  • RPM reduction by introduction of smaller size pulleys
  • Replacement of inefficient pumps
  • Replacement of soft water with foul condensate in oxygen bleaching in RGP
  • Reduction of film press pit agitator drive motor pulley diameter from 430 mm to 410 mm for power-saving
  • Commissioning of producer gas plant to save furnace oil in rotary lime kilns (50% replacement of oil with producer gas)
  • Commissioning of lime mud CD filter and rotary lime kiln for better fuel efficiency
