Improvement in the dissolving pulp production process

Two interns will collaborate with Neucel Specialty Cellulose (Neucel), which is located in Port Alice, British Columbia. Neucel is one of the leading global manufacturers of dissolving pulp, which has very high alpha-cellulose content (90 percent and over). The mill has identified the big variation in the solids content in its concentrated red liquor fed to the boiler as its priority project to improve the mill operation efficiency.

To minimize the variation and stabilize the solids contents within the mill’s target range, the two interns will determine the cause of the red liquor variation, set up an on-line solids content measurement system for three evaporation lines, and build a database to identify and provide practical solutions to the issue so that the recovery boiler performance, as well as the entire operation efficiency, can be improved. The proposed project is directly relevant to the improvement of the process operation at Neucel and has a great technology transfer potential. The project has provided excellent opportunities for the two interns.
