Abstract
In this paper, we study the protective effectiveness of the inhibitory composition (25–200 mg/L) against carbon steel corrosion in model formation waters NACE and M1 containing 400 mg/L of H2S individually and together with CO2 using gravimetry, potentiodynamic polarization, and impedance spectroscopy. Its ability to affect the diffusion of hydrogen into the metal and the development of sulfate-reducing bacteria is also estimated. Under static conditions, the protective effect is 73% in the NACE environment and 62% in the M1 environment at room temperature and 74 and 83% at 80°C, respectively. Under hydrodynamic conditions, the protective effect of the composition in the presence of a hydrocarbon phase (10%) reaches 90% in the NACE environment and 77% in the M1 environment. The inhibitory composition accelerates the diffusion of hydrogen into the metal and suppresses the growth of sulfate-reducing bacteria in the Postgate nutrient medium.
期刊介绍：
Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
