Process changes for reducing pressure vessel cracking caused by aqueous sulfide corrosion; 1992 plenary lecture

Cracking of carbon steel pressure vessels is a major problem in the petroleum refining industry. This type of cracking is one of several forms of hydrogen-related damage caused by aqueous sulfide corrosion. Process changes for minimizing corrosion, including control of water carry-over, corrosive constituents, and cyanide content are reviewed. Use of corrosion inhibitors is also discussed
