Avoid sulfuric acid corrosion in metallic stacks

Use these guidelines to prevent condensation of acidic gases

Gomes, J. F. P., Centro de Tecnologias Ambientais ISQ--Instituto de Soldadura e Qualidade

Acidic gaseous effluents frequently cause corrosion in metallic stacks. A method for determining probability of corrosion caused by gaseous effluents containing sulfur oxides based on the sulfur trioxide and moisture content measured in the stack is presented. Scope of the problem. To improve thermal efficiency of boilers and other combustion equipment, it is necessary to cool gaseous effluents to an outlet temperature low enough to maximize energy recovery. However, this temperature should not be so low that gaseous sulfur compounds in the gaseous effluents will condense. This condensation process can easily result in precipitating highly corrosive sulfuric acid. This is boun
