*The conference, scheduled to take place March 15-19, has been postponed until June 14-18. Stay turned for our new presentation date and location coming soon! 

PinnacleART’s Principal of Corrosion Technology, Fred Addington, will be presenting, “Low H2S High Temperature Sulfur Attack In Refining Hydrotreating Processes,” at CORROSION 2020, hosted by NACE International. To learn more about the conference or to register, visit the official CORROSION 2020 website.

About the Presentation

There are three known types of high temperature sulfidation present in the refining industry. Two of them (sulfidation with and without hydrogen present) have industry created methodologies for damage prediction, and they both manifest in general thinning morphologies. The third type, although recognized, does not have an accepted chemical theory or a prediction tool, and it manifests in a localized thinning morphology. This third type of sulfidation is much less common and occurs in units and process conditions where little-to-no H2S would be expected to be present.

This presentation will discuss the operating conditions in two known damage cases that likely failed through this third type of sulfidation and will provide a viable chemical theory that could lead to the observed damage profile. In addition, an approach to mitigation of this attack will be discussed. For more information and to view co-presenters, check out the conference agenda here.

About Fred Addington

With more than 25 years in the industry, Fred Addington serves as the Principal of Corrosion Technology. Fred is responsible for training, advising and disseminating technical knowledge to project teams and developing efficient management processes so team members can deliver quality services and solutions to clients. Fred’s expertise includes his understanding of processes and equipment in the area of corrosion control and material selection in the upstream and downstream oil and gas, water and petrochemical industries. Specifically, his knowledge includes corrosion and metallurgical analysis, corrosion control and monitoring, material selection, hydrogen permeation technology and mechanical integrity.

He is a member of the National Association of Corrosion Engineers (NACE) and has held various chair positions on technical committees. In addition, he has published multiple papers for NACE on topics including “Aggressive Corrosion of 316 Stainless Steel in an Amine Unit” and “Hydrogen Permeation Application to Crude Unit Overhead Corrosion Monitoring.”
