Results: Here we used FTCM to characterize pulps made from softwood and hardwood that were prepared using Kraft or chemical-thermo-mechanical pulping. Comparison of chemical analysis (NREL protocol) and FTCM revealed that FTCM results were consistent with chemical analysis of the hemicellulose composition of both hardwood and softwood samples. The mechanical drying of wood chips is an innovative method that improves the heating value of sawmill by-products in an energy-efficient continuous process. The liquid that comes out of the wood chips as press water (PW), however, contains a variety of undissolved as well as dissolved organic substances. The disposal of the PW as wastewater would generate. The refining of one tonne of mechanical pulp typically requires 800 to 3500 kWh of electricity. For example, at a cost of $0.10/kWh, the cost of electricity is $80 to $350/tonne pulp. This high cost reduces the competitiveness of the pulp in some applications and. • Thermal vapor recompression (thermocompression) can be used to give a triple effect evaporator the same energy economy as a quadruple effect plant with a corresponding reduction in investment. .

Versions of refiner mechanical (or alphabet) pulping Increased use of heat and chemicals improves fibre quality and decreases yield Various chip pretreatments may be used: •RMP = Refiner mechanical pulp: no pretreatment Yield 93-95% •TMP = Thermo-mechanical pulp: steam pretreatment 120-130 oC for 1 - 3 minutes => yield 85-90%. Chemi-thermo mechanical pulping (CTMP) involves the application of chemicals to the wood chips before refining. The process starts with the penetration of 2% to 5% of sodium sulfite and chelating agents at a pH of 9 to 10. The mixture is heated for 2 to 5 minutes at the temperature of about 120 to 130 °C and is subsequently refined. Several pulping processes can be used in the production of MDF panel fibers, such as chemical, physical or purely mechanical ones, besides the combination of some or all of them19. In the chemo-thermo-mechanical pulping process, an interrelation occurs between time and heating temperature variables and the minimal quantity of chemical reagents.

Panjiva uses over 30 international data sources to help you find qualified vendors of thermo mechanical pulp. Pelletier, A. (2017). Enzymatic pretreatment of wood to reduce energy consumption in thermo-mechanical pulp refining. Chemi-thermo-mechanical pulping (CTMP) involves the impregnation of wood chips with a combination of steam and chemicals to soften the lignin before mechanical refining . The lignin-softening chemicals such as carbonates, hydroxides, sulfite, and peroxides and further pretreatment at higher temperatures break the wood structure apart and remove lignin [ 42 ]. In order to study the potential of this concept, treatment of thermo-mechanical pulp (TMP) fines fractions were studied by means of homogenization. It seems possible to homogenize fine particles of thermo-mechanical pulp (1% w/v) to NLC. A corresponding fines fraction from bleached kraft pulp (BKP) was tested as a reference at 0.5% w/v.
