| Abstract: | Corrosion mechanism, with reference to various corrosions, e.g. high temperature hydrogen corrosion, sul- fur corrosion, wet hydrothion corrosion, stress corrosion, etc., and factors that impacting such corrosions against the CO shift unit were discussed, taking the CO shift unit in a methanol synthesis plant posed on the material selection of the pipes according to the gas composition and areas as a case in point. Suggestions were pro- operating conditions at different operating |
