Open Seminar at Karlstad University Seminar Series Organized by the Department of Engineering and Chemical Sciences Autumn Semester 2017

gives a seminar entitled
The influence of dissolved lignin in the first part of the pulp fibre line
Time: Monday, September 25th at 2:30 p.m.
Place: Room 3B 512
Abstract:
The dissolved lignin in the pulp suspension represents a significant fraction of the total lignin content in the earlier stages of the pulp mill. Since most mills base their process control on the lignin content in the fibres, they underestimate the total lignin content. The development of a new sensor that accurately measures the dissolved lignin content has offered a solution to the difficulties of process control with respect to dissolved lignin content. Implementing the new sensor will allow the mills to account for the variability in their processes and act preventively, by e.g. optimizing upstream washing operations. Mills can also use a feedforward concept that will reduce chemical consumption and maintain the target brightness, i.e. gain a better pulp evenness.
