The Impact of Temperature on CO2 Corrosion and the Formation of Corrosion Product Film

Corrosion
The impact of temperature on CO2 corrosion was investigated by weight loss, in situ electrochemical measurements, and characterization of corrosion product film. The results showed that with the increase of temperature, corrosion rate decreased remarkably, which can be ascribed to different product films formed on metal surfaces.

An Electrochemical Model for Prediction of CO2 Corrosion

CORROSION 1995, 1995
Abstract A predictive model of CO2 corrosion, based on modelling of individual electrochemical reactions occurring in a water - CO2 system, is presented. The model takes into account the following electrochemical reactions: hydrogen ion reduction, carbonic acid reduction, direct water reduction, oxygen reduction and anodic dissolution of

Corrosion Layer Breakdown and Localized Corrosion in CO2/H2S Environments

CORROSION 2012, 2012
Abstract The results of flow loop corrosion experiments carried out with 5 bar CO2, 0.5 bar H2S, 50% MEG and 60°C are presented and discussed in detail, with focus on development of localized corrosion attacks and the composition and morphology of corrosion product layers.

Environmentally Friendly Inhibitors for CO2 Corrosion

CORROSION 2002, 2002
Abstract There is an increasing need in the petroleum industry to develop green products due to more severe environmental legislation. Recently, several environmentally friendly corrosion inhibitors became available commercially. We evaluated the performance of five of these commercial green corrosion inhibitors in CO2 saturated 3 ...

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 ...

Mississippi CO2 Project - Corrosion Control

CORROSION 1986, 1986
Abstract Shell Western E&P Inc.'s Mississippi CO2 Project is composed of the CO2 source wells at Northeast Jackson Dome and three flood fields: Little Creek, West Mallalieu, and Olive. Project design has been dominated by the need for a comprehensive corrosion control plan.

Effect of Slug Flow on CO2 Corrosion

AIP Conference Proceedings, 2010
Multiphase flow induced CO2 corrosion has resulted in serious losses in oil and gas production. In this paper, gas‐liquid two‐phase vertical upward slug flow has been analyzed from aspects containing flow structure, hydrodynamic characteristics, mass transfer characteristics and their effects on pipe wall and corrosion product film, and it is found ...

In Situ Observation of Localized CO2 Corrosion

CORROSION 1994, 1994
Abstract A glass window in a pressurized flow loop has allowed observation and documentation of the progression of localized CO2 corrosion. Low-angle lighting was found to optimize the visual appearance of the corroded surface. A photographic record of the propagation of localized corrosion was made along with measurements of iron counts,

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.
