“…Currently, the minimum water content required in dense phase CO2 for acid formation in the presence of SO2 is not known [26] , but the detection of FeSO3 and FeSO4 on the steel surface in numerous experiments indicate that reactions occur at water contents considerably lower than the water solubility in pure CO2-H2O systems [3,4,26,76,78,79] . It is still not clear whether SO2 reacts with water in the bulk solution to form an acid, or if a thin condensed layer of water is initially formed on the steel surface which then reacts with SO2.…”

“…Within this system, compounds will partition between the two phases and the concentration of impurities such as water, SO2 and NO2 will become more concentrated in the remaining liquid phase. [26] When the water solubility in a particular phase in exceeded, a third phase can also form. The accumulation of such impurities can increase the corrosivity of the liquid phase significantly.…”

“…It is worth noting that the specifications outlined in Table 4 do not fully take into account cross-reactions between impurities (except for H2S and CH4 impact on water solubility through the DYNAMIS study) and no interactions between H2O, SOx and NOx were considered in the development of these guidelines. [26] It is also important to stress that the NOx and SOx limits recommended by DYNAMIS were justified based on health and safety in the event of a sudden release, not from the perspective of maintaining pipeline integrity.…”

Carbon Capture and Storage (CCS) has been highlighted as a potential method to enable the continued use of fossil-fuelled power stations through the abatement of carbon dioxide (CO2). A complete CCS cycle requires safe, reliable and cost effective solutions for the transmission of CO2 from the capturing facility to the location of permanent storage. In subsequent sections, early laboratory and field corrosion experience relating to natural dense phase CO2 transport for the purposes of enhanced oil recovery (EOR) are summarised along with more recent research efforts which focus on identifying the role of anthropogenic impurities in the degradation processes. For each system impurity, the reaction rates, mechanisms and corrosion product composition/morphology expected at the steel surfaces are discussed, as well as each component's ability to influence the critical water content required to initiate corrosion. Potential bulk phase reactions between multiple impurities are also evaluated in an attempt to help understand how the impurity content may evolve along a long distance pipeline.The likelihood of stress-corrosion cracking and hydrogen-induced cracking is discussed and the various corrosion mitigation techniques which exist to control degradation to acceptable 2 levels are reviewed. Based on the current research performed in the context of impure dense phase CO2 corrosion, issues associated with performing laboratory experiments to replicate field conditions and the challenges such limitations present in terms of defining the safe operating window for CO2 transport are considered.

14The general and localized corrosion behavior of X65 carbon steel and 5Cr low alloy steel 15were evaluated in a water-saturated supercritical CO 2 environment in the presence of 16 varying concentrations of O 2 . Experiments were performed at a temperature of 35°C and a 17 pressure of 80 bar to simulate the conditions encountered during CO 2 transport and injection. 18Results indicated that increasing O 2 concentration from 0 to 1000 ppm caused a progressive 19 reduction in the general corrosion rate, but served to increase the extent of localized 20 corrosion observed on both materials. Pitting (or localized attack) rates for X65 ranged 21 between 0.9 and 1.7 mm/year, while for 5Cr rose from 0.3 to 1.4 mm/year as O 2 22
