Improvement of energy efficiency in TMP refining by selective wood disintegration and targeted application of chemicals by Lars Johansson, Jan Hill, Dmitri Gorski and Patrik Axelsson
The article presents a state-of-the art review of the new ATMP (Advanced Thermomechanical Pulp) process and shows that up to 40% reductions in refining energy demand can be achieved
Process outline includes defibrating pre-treatment in Impressafiner and Fiberizer as well as elevated first stage refining intensity by means of using more aggressive feeding segments and higher rotational refiner speed. These process modifications, together with the addition of chemicals in the first stage refiner after pre-treatment, result in improvement of energy efficiency in refining and quality of pulp.
