“…[76] Some authors have also demonstrated a noticeable synergy existing between SO2 and O2 which results in the synergistic corrosion rate being greater than the sum of the individual corrosion rates from the presence of SO2 and O2 individually. [4] This observation is attributed to the ability of O2 to react with SO2 and water to produce sulphuric acid (H2SO4), as will be discussed later.…”

“…In additional tests, Brown et al [76] reduced the water content to 50 ppm. At such low water content, all general corrosion rates were below 0.005 mm/year for SO2 contents up to 100 ppm and O2 concentrations up to 10000 ppm (at 10.0 MPa and 4/50°C).…”

“…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.…”

“…The research by Hua et al [78] and Brown et al [76] highlight that reducing water content is a more favourable option compared to reducing SO2 content to minimise internal pipeline corrosion during transportation, as significant level of pitting corrosion were still observed in the absence of SO2 when water content was high enough. …”

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.

The transportation of CO2 from the capture site to the storage location is a crucial phase in carbon capture, utilisation and storage (CCUS) process. For offshore operations, ship transportation is considered a viable alternative, and this would entail operations at low temperatures (down to 223.15 K). A review of the literature revealed that there is limited experimental data on CO2‐rich systems at low temperatures, thus, the need to investigate the phase behaviour of CO2‐rich systems at these conditions. This study validated and compared the accuracies of Peng–Robinson (PR) equation of state (EoS) with three different mixing rules (the classical with original and adjusted binary interaction parameters, the Wong–Sandler, and the Orbey–Wong–Sandler mixing rules) against the multi‐fluid helmholtz energy approximation (MFHEA ‐ with original and adjusted binary‐specific reducing parameters) EoS in the prediction of bubble points of CO2‐rich binary systems (CO2‐CH4, CO2–O2, CO2–Ar, and CO2–N2) for CCUS applications. The experimental studies used for the validation of the models were conducted at low temperatures (228.15–273.15 K with overall uncertainties of 0.14 K) and for five different CO2 mole ratios (99.5, 99, 98.5, 98 and 95% with overall uncertainties of 0.032%) using the constant composition expansion method. The overall uncertainty of the pressure measurements was 0.03 MPa. From the study, it was observed that there was a significant effect of binary interaction parameters (BIP) adjustment on the performance of PR‐EoS with classical mixing rule, especially for the CO2–N2 system. For all the systems, the predictions of PR‐EoS with the classical mixing rules and the adjusted BIPs were the most accurate in terms of the average absolute deviations from the experimental data. The model also predicted the literature data well in comparison with the other models (with less than 5% deviations for all the data points). Further analysis also proved that the model dew point predictions were in reasonable agreement with the available literature data at the considered conditions. As a result, the model could be adopted to fill the existing knowledge gaps of the studied systems at conditions (143.15–223.15 K) where experimental studies were not feasible. © 2024 The Author(s).
