“…PTA can also be synthesized using SO 2 . However, due to the lower corrosivity of SO 2 compared to H 2 S, the resulting PTA solutions exhibit lower reactivity [17]. Furthermore, the initial ratio of SO 2 to H 2 S can significantly impact the nature of the reaction products.…”

Polythionic acid (PTA) corrosion is a significant challenge in the refinery industry, leading to equipment degradation, safety risks, and costly maintenance. This paper comprehensively investigates the origin, progression, mechanism, and impact of PTA corrosion on various components within refinery operations. Special attention is afforded to the susceptibility of austenitic stainless steels and nickel-based alloys to PTA corrosion and the key factors influencing its occurrence. Practical strategies and methods for mitigating and preventing PTA corrosion are also explored. This paper underscores the importance of understanding PTA corrosion and implementing proactive measures to safeguard the integrity and efficiency of refinery infrastructure.

“…SO 2 is a species mostly causing sulfidation and enhancing corrosion of heating surfaces in coal, biomass-fired or WTE boilers. ,− In WTE boilers, it is also considered as an intermediate in chlorine corrosion by reacting with alkali metal chlorides to generate Cl 2 . Metal corrosion in pure SO 2 or an oxidizing atmosphere containing high concentrations of SO 2 has been studied extensively over the last decades. − In earlier studies, a higher corrosion rate was usually observed in gases containing SO 2 than that in O 2 , which was attributed to the formation of sulfide phases on the scale/metal interface. ,, However, the effect of SO 2 is still ambiguous.…”

Severe corrosion to superheater tubes at high temperatures was gained virtually by gaseous corrosion media, such as HCl and SO 2 , in the municipal solid waste incineration flue gas. To clarify the effect of varying concentrations of HCl and SO 2 in the oxidizing atmosphere on the corrosion of 12Cr1MoV, a commercial alloy used in superheaters, two series of corrosion tests under simulated flue gas were performed. Both the corrosion kinetics and corrosion morphology were measured in this work. The results of the present study demonstrated that the addition of HCl was more corrosive than that of SO 2 under an oxidizing atmosphere. The increased HCl concentration had an accelerating effect on the corrosion rate, but the relation between the two was not linear. In contrast, SO 2 exhibited a negligible or even inhibitory effect on corrosion. Both series of test results consistently proved that the temperature had a significant influence on the corrosion of 12Cr1MoV alloy, in particular at 580 °C.
