• A model assignment
• Presentation of the assignments
• Visit to a pulp mill
• Visit to a LignoBoost pilot plant

Course goals

The student will after the course have a good knowledge about process changes that affect the sodium/sulfur balance. He/she will also be able to make simulations of how much a process change will influence the sodium/sulfur balance for a given mill. The student will finally have a better general understanding of the existing process chemistry in a pulp mill.

Prerequisites

You must have passed KTADM1 Pulp Technology, Advanced Course, 7.5 ECTS credits and KTADM2 Pulp Technology, Advanced Course Part II, 7.5 ECTS credits or equivalent.
