Tittel

Corrosion and Scale Formation at Carbon Steel in Sour Aqueous Solution at Elevated Temperature

Sammendrag

Films of ion sulfide generally form at carbon steel subjected to sour aqueous solutions. The protective ability of surface films is highly dependent on the conditions during which they were formed. At elevated temperature the possible formation of iron oxides may also become important. In this work the corrosion of UNS K03014 carbon steel has been investigated in autoclave tests in the temperature range 90–150 °C with 10 bar H2S and 10 bar CO2. Average corrosion rates were obtained from the total mass loss, while localized corrosion was evaluated from the surface profile of corrosion coupons. Also, the corrosion products were investigated using X-ray diffractometry (XRD) and scanning electron microscopy (SEM) equipped with energy dispersive spectrometry (EDS).
