... ABSTRACT Dewpoint corrosion is a well-known phenomenon in flue gas stacks and refinery overheads, where fine water droplets condense from the vapor upon cooling, and the acid gases in the vapors diffuse into water droplets to form a highly corrosive low pH liquid. We have identified a similar...

... ABSTRACT Corrosion in crude distillation unit overhead lines is primarily caused by hydrochloric acid at the dew point. Various other contaminants including air, organic acids, H2S, NH3, tramp amines, HCN, mercaptans, phenols, etc. also play a role in overhead corrosion. Mitigation strategies...

It was reported previously that some commercial CI (CI#1) could significantly reduce the barite inhibition performance of diethylenetriamine penta(methylene phosphonic acid) (DTPMP), phosphino polycarboxylic acid (PPCA) and poly(vinyl sulfonate) (PVS), but other tests found CI (CI#2...

Strong acids are handled exceptionally well by many fluoropolymers, and certain copolymerization reactions with materials such as PVDF can provide a material that holds up to even more challenging situations. This paper will summarize the most commonly used fluoropolymers...

... investigated in this work. Overall corrosion loss rates in boiling 20%HCl acid were similar, irrespective of the type of welding method. Intergranular penetration attack occurred at the heat-affected-zones (HAZ) of all three as-welded 0.5"-thick plates and was more pronounced near the weld root. GMAW samples...

... ABSTRACT Corrosion in acidic solutions frequently leads to equipment failure in industry. The ability to model corrosion in acidic solutions is thus necessary to increase asset integrity. A prerequisite for any corrosion model is the accurate knowledge of solution thermodynamics. In this study...

For example, it was shown that sulfuric and nitric acid can be formed for certain undesirable impurity combinations and concentrations,1 see reactions 1 through 5. Elemental sulphur may also form in some situations (reaction 6).2 H2S + 3NO2 SO2 + H2O + 3NO 2NO + O2 2NO2 SO2...
