Introduction:

Valmet has received an order to supply an upgrade of the evaporation plant at BillerudKorsnäs Gruvön pulp and paper mill in Sweden. The evaporation plant in a mill concentrates black liquor from the pulp cooking process.

Features:

In this project, the existing evaporation train will be converted, from using medium-pressure steam as today's heating media, to become essentially low-pressure steam driven. This will optimize the overall steam balance at the Gruvön mill by making medium pressure steam available for the mill's new liquid board machine that will be installed at the mill.

From the evaporation plant the evaporated water is brought back to the pulp process in order to minimize mill's water consumption. After evaporation the concentrated black liquor is fired in the recovery boiler for steam generation and recovery of cooking chemicals.

New equipment to be installed includes a TUBEL evaporator, two Tube Evaporators, two liquor preheaters, and Valmet's patented LP-steam boosting system. A substantial upgrade of the piping system will also be performed as part of the plant upgrade.

The installation of the new equipment is scheduled for spring 2018.
