Latest Patents

Aki Vilpponen holds a patent for a method of intensifying the washing of a fiber suspension. This invention focuses on decreasing the lignin content of a fiber suspension by extracting it more effectively. Traditional lignin removal processes typically operate at a consistency of less than 3%, which leads to high energy consumption. Vilpponen's method allows for a considerable increase in the consistency of the suspension, thereby significantly reducing energy requirements compared to prior art methods. A key feature of this invention is the extraction of dry substance and chemicals contained in the fibers at raised pressure and temperature.
