Columbia Pulp - Design and Engineering Services 400 tdp Non-Wood Fibre Pulp Mill
Columbia Pulp has engaged Allnorth Americas LLC (Allnorth) to provide design and engineering services for their recently permitted and developed 400 tons per day (tpd) straw pulp mill, which will serve the growing demand for sustainable non-wood fiber in North America. The site is located in the heart of one of the densest wheat farming regions in North America, on the Snake River in Washington State. Allnorth’s scope will include the mechanical, piping, structural, electrical, and instrumentation design, and control work, in addition to procurement support and field engineering for the commissioning and start-up of the mill.
The purpose of the facility is to produce high-quality, commodity and specialty straw pulp for direct sale to paper and packaging manufacturers as an alternative to wood-based pulp material. The pulp produced by Columbia Pulp will have quality specifications equal to or better than virgin hardwood pulp or recycled pulp. The lignin by-products of the pulping process are collected, concentrated and loaded onto railcars for use in a number of applications, including de-icing, dust suppression, etc.
The plant includes a cogeneration system to produce steam and power for the pulping process, rail and truck loading facilities for transporting straw, by-product and chemicals, and a warehouse with truck dock for shipping the straw pulp.
