Energy efficiency and modelling of vacuum dewatering in modern tissue machines

The project is a research coproduction between the research environment Pro2BE at Karlstad University, Valmet and Albany International about energy efficiency of tissue production. The project is aimed at acquiring deeper knowledge about tissue vacuum dewatering and at modelling vacuum dewatering during tissue production, both with a conventional tissue manufacturing method (DCT) and with Through Air Drying (TAD). It will contribute to the efforts of implementing a circular forest-based bioeconomy by increasing the fundamental understanding of dewatering of tissue materials, by several studies in laboratory and pilot scale, as well as modelling work. We believe that improved knowledge of tissue dewatering mechanisms, forming and material transport during and after dewatering can increase efficiency of processes.
