EIS Investigation of CO2/H2S Corrosion

CORROSION 2004, 2004
Abstract 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, 2018
High-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.

Integrated CO2 Corrosion - Multiphase Flow Model

SPE International Symposium on Oilfield Corrosion, 2004
Abstract 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.

Controlling CO2 Corrosion with Inhibitors

CORROSION 1998, 1998
Abstract 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, 2005
Abstract 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 Electrochemical of CO2 Pipeline Steel

2018
The 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 ...

CO2 Corrosion in Wet Gas Systems

CORROSION 1996, 1996
Abstract The failure of a pipeline used to transport wet CO2 containing gas has highlighted the limitations that both intelligent surveys and ultrasonic testing (UT) inspection can have for the detection of internal grooving type corrosion.

Assessment and comparison of CO2 corrosion predicition models

SPE International Oilfield Corrosion Symposium, 2006
Abstract A number of different CO2 corrosion rate prediction models have been developed for application in oil and gas production systems and are readily available in the literature or as industry standards. These models vary from the empirical models to the more recently developed mechanistic models.

High Salt Concentration Effects on CO2 Corrosion and H2S Corrosion

CORROSION 2010, 2010
Abstract The general CO2 corrosion rates of C1018 carbon steel have been measured for NaCl concentrations 3 – 25 wt% at 20°C, pH 4.0, 5.0 and 6.0. The corrosion process was monitored by linear polarization resistance and potentiodynamic sweeps.
