Catalyst Paper Corporation’s Crofton Division (Catalyst) is an integrated paper and pulp manufacturing facility with two operating paper machines and two pulp machines. Major products include newsprint, directory paper, and kraft pulp, which is used to manufacture printing, writing, and tissue papers. The Mill is located on Southern Vancouver Island near Duncan, BC.

The Kraft Mill consists of three pulping lines. Each line is equipped with five pressure screens in the brownstock area for a total of 15 pressure screens. Advances in screening technology have resulted in the ability to retrofit the screens with new technology rotors and screen baskets providing a substantial reduction in power intensity through the screening process.

Allnorth was engaged by Catalyst to provide an EEFS and associated capital cost estimate as preliminary engineering for the of the reconfiguration of the screening circuit, with associated changes to the system’s process piping and process control.

Allnorth worked with the client to develop the mechanical and piping preliminary design criteria for the project and to analyze the requirements for process control, drive changes and motor changes.

Allnorth also provided an EEFS Study report including Class 30 Capital Cost Estimate for the implementation Project. The report included the energy demand reduction, energy consumption savings, and energy cost savings as compared to the identified baseline.
