In this weeks article, The use of alloy materials in modern sulfuric acid plants, by Andrew Pedersen from NORAM Engineering and Constructors, Ltd., we look into how sulfuric acid plants are often considered to be permanent installations, which means they need to be upgraded and maintained indefinitely with no fixed life-time. While many plants are now in operation with no remaining original equipment, this has been made possible not only by a chance in attitude, but also by the sulfuric acid industrys adoption of alloy materials in most areas of acid plants.
Alloy materials reduce corrosion and erosion, are more easily repaired and maintained, and prevent fouling products from plugging up major equipment. Alloy materials are of particular value in maintaining plants where existing equipment is being replaced during turnaround, as the reduced weight and weldability can significantly reduce installation time, Pedersen explains. Also, lighter equipment also alloys the re-use of existing foundations, despite changes in local construction codes.
