Pulping Optimization

Confidential Client

In 2014, Allnorth was retained by a confidential client to provide design and engineering services for their pulping optimization project. Allnorth’s scope of work included the cooking system and associated balance of plant changes, diffusion washer, blow tank, polysulfide liquor preparation, high-density pulp storage, and bleach plant upgrade. As the world’s first purpose-built polysulfide pulp digester, this transformative project sets new industry benchmarks for pulp yield, energy conservation and reduced emissions.
