Evaluation of strategies in decreasing energy consumption at Irving Paper byfractionation

The thermo mechanical pulping (TMP) process uses large amounts of electrical Energy to

turn wood chips into separated pulp fibers suitable for papermaking Hecent advances being

developed by supplier-mill partnerships employ fiber fractionation processes between refining stages to achieve significant reductions in total energy consumption During this

internship these new processes will be investigated to understand how the discrete process

stages impact the resultant fiber fractions and overall pulp properties, and its implication to

[he operation at irving Paper These will be done by conducting bench and pilot-scale

fractionation and refining equipment. Pulp and fiber properties will be determined, thus

identifying the process configuration with the best potential for decreasing the energy

consumption while maintaining pulp properties
