This study arises from the development of carbon capture and storage technology (CCS) as a means of disposing of the large quantities of CO2 emitted by industry. In particular the need is identified to measure the impact of impurities such as N2 and H2 on solubility of H2O in dense phase CO2 since the formation of an aqueous phase in CO2 bearing carbon steel pipelines presents a risk of corrosion or blockage. Chapter 1 describes this background, paying attention to the current state of affairs with regard to the development and deployment of CCS. An historical review is undertaken of the significant body of literature reporting the maximum H2O content of pure CO2. Analytical sampling methods are found to predominate in this literature, but particular attention is paid to several in situ infra-red methods upon which this thesis builds. The significant mathematical model of Spycher et al. is described along with equations of state relevant to the thesis. A discussion is presented of the limited literature concerning the effect of impurities on the H2O content of CO2. The aims of the thesis are then clearly set out: they pertain to the accurate measurement of H2O solubility in pure and impure CO2 at conditions relevant to CCS pipelines by an in situ infra-red method.
