RTS PulpingCosts & Benefits
|Parent Process: Mechanical Pulping|
|Energy Savings Potential||
A study estimates RTS pulp can be manufactured with about 15% lower specific energy requirements than pulp produced with conventional refining system. Another study reports specific energy of RTS pulping process 20% lower than Thermo-mechanical pulping. Increasing rotational speed on TMP refiners are estimated to reduce energy use between 15 to 30%, depending on plate type and refiner mode (Kramer et al., 2009. p.99).
|CO2 Emission Reduction Potential||
Emission reduction potential is estimated at 128 kg CO2/t-pulp (Martin et al., 2000. p. 21)
Implementation costs are estimated around $50/t-pulp (estimation from the year 2000) (Martin et al., 2000. p. 24)
For a typical mill with 1000 ton per day capacity, a reduction of 20% in motor power requirement translates into $5 million annual savings (Sabourin, 2006).
