Refiner ImprovementsCosts & Benefits
|Parent Process: Mechanical Pulping|
|Energy Savings Potential||
A newspaper mills applied refiner control strategy to minimize variations in the freeness of ultra high yield sulfite pulp saved 51.3 kWh/t product.
By decreasing consistency of pulping from 50% to 30%, 7 to 15% electricity savings possible in Thermo-mechnical and refiner mechanical pulping.
Savings due to mechanical improvements are estimated at 11%. (Kramer, et al., 2009. p.96)
Double disc refiners used in some Swedish and Norwegian mills consume aroun 300 kWh/t less energy than single disc refiners (BREF, 2010. p. 471).
|CO2 Emission Reduction Potential|
Potential electricity savings of 11% may be achieved at the capital cost of around $7.7/ton (2000 dollars) of pulp production (Kramer, et al., 2009. p.96).
