“…Such a process can be intermittent and unreliable during long term testing. To overcome this issue, Thodla et al [23] and Ayello et al [110] administered water droplets to the steel surface in-situ at high pressure to maintain conductivity. However, such a thick water film may not be wholly representative of the films encountered in a CO2…”

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.

“…Elemental Cr induces a transition of the corrosion product from the crystalline to the amorphous state, which results in a denser corrosion scale and decreased susceptibility to localized corrosion [12]. As previously mentioned, the corrosion behavior of steel in a CO 2 environment is affected by H 2 O and O 2 impurities [13] and by the Cr content of the steel [14][15].…”

Abstract:The corrosion behaviors of X52, 3Cr low-alloy steel, and 13Cr stainless steel were investigated in an O 2 -H 2 O-CO 2 environment at various temperatures and O 2 -CO 2 partial-pressure ratios. The results showed that the corrosion rates of X52, 3Cr, and 13Cr steels increased with increasing temperature. The corrosion rates slowly increased at temperatures less than 100°C and increased sharply when the temperature exceeded 100°C. In the absence of O 2 , X52, 3Cr, and 13Cr exhibited uniform corrosion morphology and FeCO 3 was the main corrosion product. When O 2 was introduced into the system, various forms of Fe 2 O 3 appeared on the surface of the samples. The Cr content strongly influenced the corrosion resistance. The 3Cr steel with a low Cr content was more sensitive to pitting than the X52 or 13Cr steel. Thus, pitting occurred on the surface of 3Cr when 1.25 MPa of O 2 was added; this phenomenon is related to the non-uniform distribution of Cr in 3Cr.

“…A number of studies have been 21 conducted on the subject of impurities and their corrosivity in the transport of CO 2 . It has been highlighted that the presence of free water in the CO 2 stream transported via the pipeline should be avoided [74,111,123,124,[170][171][172][173][174][175]. Some of those studies that evaluated the effects of H 2 O and other impurities on corrosion in different pipeline material are summarised in Table 5.…”

Transport of carbon dioxide (CO 2 ) via pipeline from the point of capture to a geologically suitable location for either sequestration or enhanced hydrocarbon recovery is a vital aspect of the carbon capture and storage (CCS) chain. This means of CO 2 transport has a number of advantages over other means of CO 2 transport, such as truck, rail, and ship. Pipelines ensure continuous transport of CO 2 from the capture point to the storage site, which is essential to transport the amount of CO 2 captured from the source facilities, such as fossil fuel power plants, operating in a continuous manner. Furthermore, using pipelines is regarded as more economical than other means of CO 2 transportThe greatest challenges of CO 2 transport via pipelines are related to integrity, flow assurance, capital and operating costs, and health, safety and environmental factors. Deployment of CCS pipeline projects is based either on point-to-point transport, in which case a specific source matches a specific storage point, or through the development of pipeline networks with a backbone CO 2 pipeline. In the latter case, the CO 2 streams, which are characterised by a varying impurity level and handled by the individual operators, are linked to the backbone CO 2 pipeline for further compression and transport. This may pose some additional challenges.This review involves a systematic evaluation of various challenges that delay the deployment of CO 2 pipeline transport and is based on an extensive survey of the literature. It is aimed at confidence-building in the technology and improving economics in the long run. Moreover, the knowledge gaps were identified, including lack of analyses on a holistic assessment of component impurities, corrosion consideration at the conceptual stage, the effect of elevation on CO 2 dense phase characteristics, permissible water levels in liquefied CO 2 , and commercial risks associated with project abandonment or cancellation resulting from high project capital and operating costs.2
