Oxygen Bleaching

Crofton Pulp and Paper

Crofton Pulp and Paper retained Allnorth to complete the preliminary study and detailed engineering for the installation of a new two-stage oxygen bleaching system at the mill. The project included the installation of two new ASME Section VII Div I high-pressure oxygen bleaching vessels and foundations, the installation of two new MC stock pumps, a steam heater, high-pressure oxygen system upgrades with inline stock-oxygen mixers, a new Kappa Analyzer, and associated piping and plant modifications to retro-fit the new system into their B-Bleach Plant.

Crofton Pulp and Paper was the first mill in North America to implement this bleaching technology.
