Tmp refining
WebRefining at low-consistency (LC), typically at 4%, of thermo-mechanical pulp (TMP) has been reported to be an energy-saving technology, providing more efficient fibre development than refining at a high-consistency (HC) of approximately 40% (Muenster 2005). However, LC refining of TMP is not widely applied in the pulp and Webrefiners (TMP), followed later by refiners with various chemical pre-treatments and post treatments, sometimes with pulp brightening (BCTMP). The combinations of refiner type, …

The quantity of reducing sugar was used as an indicator for enzyme hydrolysis efficiency.
WebJan 23, 2024 · The key sub-processes in TMP cover all the way from chip preparation, high-consistency refining, steam recovery, fractionation, treatment of long fiber fraction, bleaching and dewatering to pulp storage … WebAn Escher-Wyss conical refiner at the SCA R&D Centre in Sundsvall, Sweden was used for LC refining. The pulp consistency during refining was about 2%, the amount of pulp used in each batch was 1.1 kg dry weight and the edge load was 1.26 Ws/m. The pulp suspension was re-circulated until the target level of refining energy was obtained.
WebRTS™ and TMP mill case studies were conducted, utilizing FiberMaxX™, FiberMaxX-EX™, and VPZ™ refiner plate patterns, to reduce refining energy, improve pulp quality and increase production rates depending upon the specific application. In the studies the refiner plate designs selected provided from 200 to 280 kwh/odmt energy reduction. WebThe main driving force in thermomechanical pulp (TMP) refiner development has been towards higher production rate refining lines. High production in the refining line offers both low investment and production costs for a paper mill. High production in the TMP line also produces pulp at lower energy consumption [1].
