Some Latest Development in Alkaline Peroxide Mechanical Pulping, 2002 Fall Technical Conference
Running primary refiner with pressurized casing and atmospheric inlet was compared with conventional
atmospheric refining in P-RC APMP pulping of aspen and birch commercial wood chips. The results showed that
both refining configurations gave similar bleaching efficiency. For some installations, using pressurized casing can
significantly simplify the process, engineering and operation of P-RC APMP process.
