Scale, Corrosion, RoHS, and FRPs – Their Impact on Today’s Mill Production
Published: July 26 2018
The Corrosion and Materials Engineering track at TAPPI’s Pulping, Recycling, Engineering, Environmental, Recycling and Sustainability (PEERS) Conference, October 28 – 31, Portland, Ore., USA, offers three sessions focusing on:
- RoHS: 10 Years Later – Process Control Equipment Corrosion Issues Remain
- Corrosion and Scale Problems in Recovery and Power Boilers in Pulp and Paper Operations
- Corrosion Resistant FRP Equipment for Pulp and Paper
Corrosion and corrosion product deposition are major concerns in utility and recovery boiler operations in pulp and paper mills. They can ultimately lead to a loss in efficiency, serious caustic attack, short and long term overheating, potential molecular hydrogen damage, and tube failures. The Corrosion and Scale Problems session will offer insights into how condensate system passivation, using blended amines plus a volatile reducing agent, temporarily reduces the impact of acid upsets and enhances better operational performance.
The European Union RoHS directive took effect in 2006, and of the six restricted materials, the elimination of lead from electronic devices took the most development effort and had the worst degrading effect on electronic hardware reliability. The RoHS session focuses on how a number of contributing factors have led to increased corrosion-related electronic equipment hardware failures associated with particulate and gaseous contamination. It also outlines the role RoHS plays in electronic equipment reliability, and how changes to air quality standards and air monitoring have led to improvements in environmental controls for process computer and control rooms, motor control centers, network and switchgear equipment.
In the Fiber Reinforced Plastic (FRP) session, attendeees will learn how FRP is viewed as the best construction material in pulp and papermaking processes due to its reliability, performance, length of service, and cost. Today’s FRP is based on epoxy vinyl ester resin (EVER) used to construct vessels, piping, bleach towers, tanks, washer drums, drum covers, hoods, ducts, and scrubbers. Attendees will review data comparing the performance of FRP to other matierlas, and also North American mill case studies that validate material selection, design criteria, and performance of FRP equipment in real world environments.
