Heat Recovery in Thermo-mechanical PulpingCosts & Benefits
|Parent Process: Mechanical Pulping|
|Energy Savings Potential||
One study estimates heat recovery systems for pressurized refiners can generate 1.1 to 1.9 tons of clean steam at dryer pressure per ton of pulp (Kramer et al., 2009. p.99).
For a 150 tpd plant, recovery of 695 GJ of energy in the form of steam and 1175 GJ of energy in the form of hot water is reported (NEDO, 2008. p.166)
|CO2 Emission Reduction Potential|
Average installation costs have been estimated to be $21/t-pulp (2000 dollars), with significant increases in operation and maintenance costs.
