...Abstract Corrosion testing of austenitic stainless steel, UNS S31603 (AISI 316L), was conducted in flow-through reactors during early stages of lab setup development with the aim to obtain a superheated steam environment with H₂S/CO₂/HCl at 350°C and 10 bars. The test fluid...

... results, the inhibition ability of both BAILs in 0.5 M HCl solution against acid corrosion of mild steel was investigated, at various concentrations at 25°C, using gravimetric measurements. The pyridinium-type sulfonate-functionalized IL did not contribute to corrosion protection of the steel surface...

... times of 24 to 72 hours. It was claimed that the new formulation was much more effective to dissolve pyrite than the 20 wt% HCl and DTPA (diethylenetriaminepentaacetic acid) solution. Later, a low-pH version (pH ~ 6) formulation was introduced. ¹² This low pH formulation showed a solubility...

... fluids can include different types of acids, such as hydrochloric (HCl), acetic, formic, or combinations of such acids. Since these can be corrosive, corrosion inhibitor packages are required to prevent severe corrosion damage to the well construction materials. Furthermore, inhibition additives for acid...

Acidizing HCl Acetic Acid Ti 6-4 Ti 6-2-4-6 C276 Tantalum Surface Alloy INTRODUCTION The specimen test rack was inserted into the autoclave and 1L of acid solution (see Table 2 ) was added to the autoclave by pouring. The autoclave was then sealed and pressurized...

...(1) NaCl + H 2 O → NaOH + 2 HCl The processing of crude oils containing high levels of naphthenic acid may exacerbate problems with the presence of salt and hydrolysis. High acid content crude oils often have higher conductivity and emulsion forming tendencies than typical crude oils...
