Sulphuric Acid (93%) Storage Tank and Piping System, Catalyst Paper
Allnorth provided detailed engineering and design services for the repair and upgrades to the 93% sulphuric acid system at Catalyst Paper’s Crofton pulp and paper mill. Equipment and piping had been damaged by a piping failure within the containment area and required a fast-track approach to repair the system. During the outage, approximately 300 feet of lined piping was installed as part of the upgrade to the distribution network. Allnorth worked closely with the mill engineering group and mill trades to design a system that included an upgraded distribution network and acid-unloading system, modifications and improvements to the acid storage tank, two new variable speed pumps, and new instrumentation to provide improved system control.
Allnorth’s responsibilities for this project included:
- Process engineering
- Mechanical engineering
- Piping design
