Summary of the lecture
This course is based on the Pulp, Paper and Biomass Industries: Materials‑Selection and Corrosion Guide (No. 11025).
It provides essential guidance for engineers, materials specialists, and plant personnel involved in designing, upgrading, and maintaining equipment used in the pulp, paper, and biomass-processing industries. The publication summarizes the corrosion behavior and performance characteristics of carbon steels, stainless steels, and nickel-containing alloys exposed to the diverse chemical, thermal, and mechanical environments found across wood handling, pulping, bleaching, chemical recovery, papermaking, and biomass-to-energy operations. Emphasis is placed on selecting safe, reliable, and cost-effective materials of construction that improve equipment integrity and service life in corrosive industrial conditions.
What you will learn:
- Understand the major corrosion mechanisms affecting steels and alloys in pulping, bleaching, chemical-recovery, papermaking, and biomass-processing environments, including the influence of temperature, chemistry, and process conditions.
- Explain the performance differences among carbon steels, stainless steels, and nickel-containing alloys and how composition, fabrication, and surface conditions impact corrosion resistance across various unit operations.
- Differentiate the material requirements for key process areas, such as wood preparation, kraft pulping, mechanical pulping, oxygen-delignification, bleaching stages, evaporators, recovery boilers, digesters, and biomass-energy systems.
- Evaluate the effects of process chemicals, liquor compositions, oxidizing and reducing environments, chloride levels, and pH on alloy selection and expected service performance.
- Identify appropriate alloys and fabrication practices to mitigate corrosion, stress-corrosion cracking, pitting, and crevice attack in equipment such as piping, vessels, heat exchangers, washers, digesters, tanks, and recovery systems.
- Interpret corrosion data, comparative alloy tables, and application-specific recommendations to make informed, cost-effective materials-selection decisions for pulp, paper, and biomass facilities.
