Veolia to upgrade Fibre Excellence’s Saint Gaudens mill concentration and evaporation processes
Aubervilliers in Seine-Saint-Denis, Paris - Veolia Water Technologies will provide a turnkey processing plant featuring HPD evaporation systems designed to optimize the production of wood-derived pulp employed in making high-quality paper from virgin fibers.
At the industrial site in Saint-Gaudens on the foothills of the Pyrenees in southwestern France, Fibre Excellence, a holding group specialized in the paper and forest-products industry, is utilizing a new turbine to generate green energy from biomass. To optimize the overall efficiency and justify the economics of the investment, this extra energy must be consumed at the site. Fibre Excellence plans to enhance pulp quality through improved washing operations.
To remove the excess water created in the black liquor, Veolia supplies HPD falling film, double-effect evaporators at the pre-evaporation phase. Additionally, in order to reduce emissions and improve energy efficiency of the recovery boiler, the final solids concentration of the black liquor will be raised up to 75% through an HPD forced-circulation, enhanced high-solids concentrator (EHSC). Both the pre-evaporation and forced circulation concentration phases are integrated into the mill operations using the excess energy generated through the installation of the new turbine.
The new package is integrated with a more efficient stripping column that removes up to 96% of methanol and helps to reduce volatile pollutants.
“We are pleased to help Fibre Excellence advance its pulping operations at the Saint Gaudens mill. This award cements Veolia’s position as the partner of choice to supply reliable processing solutions that make the global pulp and paper industry more resource-efficient and sustainable. ” said Jim Brown, CEO of Veolia Water Technologies Americas.
