... ABSTRACT Selection of effective corrosion inhibitors for oil and gas fields often requires extensive laboratory testing to evaluate inhibitor performance at simulated field conditions. Due to the availability of field materials and difficulties associated with transportation, carbon steels...

... ABSTRACT The influence of flow rate on corrosion behavior of X65 carbon steel in water-saturated supercritical CO 2 phase containing 1000 ppmv H 2 S impurity was studied at 35 °C and 8 MPa from 0 m/s to 1.5 m/s. Weight loss tests showed that the general corrosion rate reached maximum...

... deposit corrosion rates for API X-65 carbon steel when the deposit consisted of iron sulfide (FeS) than for sand in a 50%H 2 S/50%N 2 environment. In addition to only H 2 S, when acid gases (H 2 S and CO 2 ) are present in the system the corrosion mechanism becomes more aggressive due to lower pH...

... ABSTRACT Millions of gallons of high-level radioactive waste are stored in underground carbon-steel storage tanks at the Hanford site. The waste chemistries are alkaline with pH between 11 and 14. Carbon steel is expected to become passive and undergo passive dissolution under the alkaline...

... ABSTRACT Corrosion of carbon steel in the presence of H 2 S is an important topic in the oil and gas industry that has been studied for more than fifty years. Removing this compound results in not only an increase in the corrosion resistance of carbon steel, but also an improvement...

... at laboratory scale. In this study, the influence of the depth on the cathodic protection criteria of carbon steel and stainless steel was investigated in intermediary (1020 m depth) and deep water (2020 m) at the same location. For this purpose, at set of corrosion and environmental sensors, as well...

... of carbon steel pipeline in high partial pressure CO 2 (pCO 2 ) environments have gained more interest recently relating to carbon capture and storage (CCS), enhanced oil recovery (EOR), and deep water oil and gas production applications.1-5 Although there are extensive research data available on high pCO...

... like oxygen or halides. At higher temperatures (>230°C) decomposition of sulfolane and formation of H 2 SO 3 may accelerate, leading to increased aggressiveness towards carbon steel. 1-4 Sulfolane’s decomposition can accelerate further when oxygen and/or chlorides are present. Pipeline...

... ABSTRACT Carbon steel is prone to uniform and pitting corrosion in geothermal brines, whereas high alloyed materials which exhibit excellent corrosion resistance are relatively costly. For these reasons, coating systems become an alternative to protect carbon steel from corrosion...

... ABSTRACT CO 2 corrosion mitigation is a challenge in the oil and gas industry. In order to decrease the severity of CO 2 corrosion of carbon steel pipelines and equipment, different mitigation practices are recommended. One such strategy is the application of surface active chemical...
