Corrosion in fertilizer industry - 1.2 Elemental sulphur attack

WATCH THE VIDEO HERE OR READ ON BELOW! Elemental sulphur attack is NOT sulphidation or hydrogen sulphide corrosion. It is an aqueous corrosion phenomenon. It considers two modes - acidification of sulphur - formation of sulphuric acid 2. direct cathodic reduction of sulphur with anodic dissolution of iron The lowering of pH is the main source of corrosion in both the methods. The phenomenon is temperature dependent. It increases with increase in temperature and becomes particularly severe above the melting point of sulphur (~112.8 degree Celsius). Hydrogen sulphide present in the petroleum may aggravate the sulphur attack by enhancing uniform pitting corrosion. Monoethylene glycol is used to prevent condensate formation ans may be present in traces in the feedstock petroleum. This enhances the sulphur attack in the form of uniform corrosion, and crevice corrosion. References: Fang, Haitao, Brown, Bruce, Young, David, and Srdjan Nešic. "Investigation...
