EIS Investigation of CO2/H2S Corrosion
CORROSION 2004, 2004Abstract This paper covers one of the building blocks required to complete a mechanistic CO2 / H2S corrosion model: electrochemistry of carbon steel CO2 corrosion in the presence of traces of H2S (3-250 ppm in the gas phase). Electrochemical impedance spectroscopy and linear polarisation resistance were used to investigate the mechanism ...

Alloy Corrosion by Hot CO2 Gases
JOM, 2018High-temperature corrosion of heat-resisting alloys by CO2 produces external oxide scales and, in many cases, simultaneous internal carburization. In general, higher alloy chromium levels are required to achieve protective chromia formation in CO2 compared with in air.

Corrosion, 2018
Production of oil and gas from increasingly aggressive geologic environments requires the development of appropriate corrosion mitigation strategies, including the selection of corrosion inhibitors with adequate performance characteristics.

Integrated CO2 Corrosion - Multiphase Flow Model
SPE International Symposium on Oilfield Corrosion, 2004Abstract An integrated CO2 corrosion - multiphase flow model was built which takes into account the effect of most important variables. The model is mechanistic in nature and resides on clear theoretical foundations.

In aqueous carbon dioxide (CO2) solutions where both Ca2+ and ferrous iron (Fe2+) are present, such as downhole gas reservoirs or deep saline aquifers after CO2 injection, mixed metal carbonates with the formula FexCayCO3 (x+y=1) can form.

Controlling CO2 Corrosion with Inhibitors
CORROSION 1998, 1998Abstract Transport of corrosion inhibitor to the location where they are needed is one of the primary concerns in the use of corrosion inhibitors. Two different types of inhibitors for controlling CO2 corrosion in gas well wellheads and flowlines are used as examples.

CO2 Corrosion Prediction Model – Basic Principles
CORROSION 2005, 2005Abstract The NORSOK M-506 is an empirical model based on experiments undertaken in a single phase water flow loop. The data is from experiments with low content of iron ions in the water phase, and the model is thus regarded to give a fair representation of the maximum corrosion rate in a CO2 corrosion controlled system. The experimental

Corrosion, 2023
Corrosion is a major concern in transmission pipelines that transport captured CO2. While dry CO2 is noncorrosive, significant corrosion has been reported in dense phase CO2 with trace amounts of water and impurities such as O2, H2S, SOx, and NOx.

Corrosion Electrochemical of CO2 Pipeline Steel
2018The greenhouse effect is having increasingly impact on global climate; corrosion resistance of pipeline steel for supercritical CO2 transportation has become an important research topic [1]. In this paper, four common pipeline steels (X65, X70, X80, X90) are electrochemically tested in a carbon dioxide saturated aqueous solution in the gas phase using ...
