Corrosion in the Chemical Processing Industry
This article focuses on the effects of process variables on corrosion of metals in various plant environments; startup, shutdown, and downtime conditions; and seasonal temperature changes. It also tabulates the effects of process variables on corrosion of metals in aggressive environments.
This article provides a detailed discussion on the corrosion of steel and stainless steel under insulation. Stress corrosion cracking mechanism, types of alloys susceptible to corrosion, factors influencing corrosion, and corrosion prevention methods, are also discussed.
This article describes the selection of materials for the production and handling equipment of concentrated sulfuric acid, depending on factors such as the allowable corrosion rate, desired mechanical and physical properties, fabrication requirements, availability, and cost. Materials such as carbon steel, cast irons, austenitic stainless steels, higher austenitic stainless steels, higher chromium Fe-Ni-Mo alloys, nickel-base alloys, non-metals, and specific other metals and alloys are also discussed.
