June 26, 2019 – ABB has supplied Port Townsend Paper Corporation (PTPC), a North American producer of pulp and paper products, with a new digital service that will allow the mill to continue operations and avoid a weeks-long shutdown.

PTPC produces kraft pulp, paper, containerboard and specialty products by blending virgin and recycled fibres at its mill headquarters in Port Townsend, Washington.
The evolution began in April 2018, when the mill’s distributed control system (DCS), which was nearing the end of its lifecycle, started a phased evolution upgrade culminating in ABB performing services and upgrades during planned downtime.
As part of the agreement, ABB migrated the mill’s existing human-machine interface (HMI) to its ABB Ability System 800xA. The System 800xA also serves as an integrated electrical control system, a safety system and a platform to enable collaboration amid operators.
The mill also added OPT800 Cook/B, which is part of the ABB Ability Advanced Process Control offering for pulp mills. OPT800 Cook/B is the latest version of the Advanced Batch Digester Management System that sequences and schedules PTPC’s batch digesters to process wood chips into pulp more efficiently, helping to increase production.
PTPC will also benefit from minimized kappa variation and steam leveling, which will result in reduced chemical and steam usage.
As part of the order, the mill also receives ABB Pulp and Paper Care, a modular service agreement framework that includes spare parts management programs, 24/7 technical support and remote support services.
PTPC also has a sister corrugated packaging facility, Crown Packaging, in British Columbia.
