Using Drum PulpersCosts & Benefits
|Parent Process: Recovered Fiber Pulping|
|Energy Savings Potential||
A study suggests that if a vat type pulper is replaced with a continuous drum pulper in de-inking operations, energy consumption reduction by over 25% can be achieved. (Kramer et al. 2009. p. 97)
|CO2 Emission Reduction Potential||
For a 300 t/d capacity plant, CO2 reductions due to reduced power demand are estimated to be 1055 t CO2/y. (NCASI, 2001. p.131)
Costs of a continuous drum or dry pulper will be higher than those of batch equipment with equivalent capacity.
