Thermopulping

Thermopulping is the variation of the TMP process in which the pulp from primary stage refiner is subjected to a high temperature treatment for a short time in a thermo-mixer and in the subsequent secondary refiner. The higher operating pressures in the secondary refiner reduce the volumetric flow of generated steam. An additional advantage is that in contrast with other energy savings technologies this process can be turned on and off as desired by mill personnel. A drawback is a small brightness loss and a slight reduction in the tear index (Kramer et al., 2009. p.98).

Energy Savings Potential

Studies suggest that this technique can reduce specific energy consumption compared to thermo-mechanical pulping by up to 20% (Kramer et al., 2009. p.98).
