Continuous Digesters: Exploring Damage Mechanisms

TAPPI’s Engineering Division and the Digester Work Group is excited to offer a new Knowledge Share and discussion focused on continuous digesters - corrosion, cracking, and other damage mechanisms. The Knowledge Share webinar will be presented by Margaret Gorog, Houghton Cascade Holdings, LLC.

The main damage mechanisms in continuous digesters are caustic stress corrosion cracking and general corrosion of carbon steel. Stainless steels can experience similar degradation. This presentation will review these damage mechanisms and cover others that affect both internal and external parts of the vessel. Additionally, corrosion and cracking of auxiliary equipment such as the steaming vessel, level tank, sand separator and flash tanks are also included.

Registration is open to all and is free of charge. The event will be held in Microsoft Teams.

Originally from the Vancouver area in Canada, Margaret received a Bachelor of Applied Science in metallurgical engineering from the University of British Columbia. She is now with Houghton Cascade Holdings, LLC and is based in Lynden, WA. She has worked in the pulp and paper industry for 35 years in corrosion control, materials selection, inspection, and failure analysis.

Margaret is very active in TAPPI and advanced through all the positions in the Corrosion & Materials Committee and Engineering Division. She is a TAPPI Fellow and is now the TIP Coordinator for the Plant Engineering and Project Management Committee.
