Valmet Vapor Recycling
Valmet’s Vapor Recycling can help save high pressure steam. The innovative vapor recycling concept makes it possible to evaporate to high dry solids using only LP steam. High pressure steam can be saved for other uses in the mill.

White liquor oxidation system
The purpose of white liquor oxidation is to improve the Na/S balance of the Kraft process by replacing make-up caustic with internally generated alkali. Valmet offers two well-proven and efficient alternatives, an air-based oxidation system for the production of partially oxidized white liquor for oxygen delignification and an oxygen-based system for the production of fully oxidized white liquor for bleaching and oxygen delignification. Oxidized white liquor can also be applied for many gas scrubbing applications.

High-performance oxygen delignification
Valmet Oxygen Delignification system removes lignin with excellent efficiency. It is the ideal oxygen delignification stage and a great asset for pulp mills. Up to 65-70% of the remaining lignin after cooking is removed. This result remains unchallenged. The secret lies in the carefully optimized conditions.

Steam Separator PS
Steam recycling is an important aspect of the energy-demanding refining process. It is a well-known fact that fiber carryover in the recycled steam can cause problems such as plugging, operating stops for cleaning and, in some cases, emitting fiber and steam into the surroundings.

Lime mud handling
Valmet’s lime-mud dewatering system ensures good washing of the lime mud and high dry-solids content.
