Valmet to supply recausticizing upgrade for Russian pulp and paper mill

The Valmet delivery includes technology for the recausticizing plant consisting of cooling, slaking, white liquor filtration and lime mud washing and drying.

In addition to the main machinery and auxiliary equipment, the order also includes automation instruments related to machinery motors and a DCS process control system.

The new design of the lime mud disc filter gives access to bearings and seals from outside the vessel, which makes maintenance easier and improves safety.

Arkhangelsk Pulp and Paper is rebuilding the plant to increase capacity and replace obsolete equipment. The start-up of the delivery is scheduled for autumn 2017.

“The rebuild will make possible to increase the capacity of the plant and reduce the considerable maintenance that is required today. The delivery is especially exciting since it is the first time we deliver our new generation lime mud disc filter - OptiDisc. The design will increase work safety and ensure mill runnability,” said Thomas Malmqvist, sales manager at Valmet.
