“…In particular, at 40°C and 10.21 MPa, the addition of 10% N2 reduced solubility of water from 4450 ppm to 3400 ppm (approximately a 30% reduction). Figure 4 (from the publication by Foltran et al [32] ) shows in more detail how N2 influences the solubility behaviour of water in CO2 at 40°C over the pressure range of 8.0 to 18.0 MPa.

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 off-gas obtained from the natural brines is composed of 86.2% carbon dioxide, with smaller quantities of nitrogen (N 2 , 9.85%) and methane (2.28%). In the literature, some studies have obtained experimental solubility data of gas mixtures in pure water: [37,38]. Nevertheless, the studied gas mixtures were not in accordance with the Upper Rhine Graben representative gas mixture.…”

With the growing interest in geothermal energy as a renewable and sustainable energy source, nowadays engineers and researchers are facing technological and environmental challenges during geothermal wells’ operation or energy recovery improvement by optimizing surface installations. One of the major problems encountered is the degassing of geothermal brines which are often loaded with dissolved gases, resulting in technical problems (scale formation, corrosion, reduced process efficiency, etc.) and environmental problems through the possible emission of greenhouse gases (CO2, CH4 and water vapor) into the atmosphere. In this work, a method to predict, from readily available information such as temperature and GLR, the bubble point pressure of geothermal fluids as well as the GHG emission rate depending on the surface conditions is presented. This method is based on an extended version of the Soreide and Whitson model with new parameters optimized on the solubility data of several gases (CO2, CH4, N2, O2 and H2) in brine (NaCl + CaCl2 + KCl). The developed approach has been successfully used for the prediction of water content of different gases and their solubilities in different types of brines over a wide temperature and pressure range, and has been applied for the prediction of bubble point pressure and GHG emissions by comparing the results with available industrial data of geothermal power plants including the Upper Rhine Graben sites.

“…In-situ spectroscopic techniques provide a tool to follow chemical reactions at the 105 4 molecular scale, assuming suitable integration with high pressure and high temperature reaction cells. In-situ infrared spectroscopy has been applied previously to study the interaction of CO2 with alkaline cations at high pressure in clays (Krukowski et al, 2015;Loring et al, 2014Loring et al, , 2012aSchaef et al, 2015), mineral carbonation reactions with silicate minerals (Loring et al, 2012b(Loring et al, , 2011Miller et al, 2013;Murphy et al, 2011Murphy et al, , 2010Thompson et al, 2013) and carbon storage related fluid mixtures (Danten et al, 2005;Foltran et al, 2015;Oparin et al, 2005Oparin et al, , 2004Wang et al, 2013). An example of the design and construction of an automated high-pressure titration system with in-situ infrared access and subsequent application to CO2 sorption in clay, carbonation of silicate mineral and determination of water solubility all at 50 °C and 90 bar serves as an excellent introduction to this approach (Thompson et al, 2014).…”

Storage of carbon dioxide in geological formations involves changes in wettability to the host formation during injection and ultimately the formation of inorganic carbonates through mineral trapping. Sequestration locations will be at high pressure and high temperature, thus providing a challenging environment for in-situ study. However, infrared spectroscopy (FTIR) with the use of photons is not limited in temperature or pressure and therefore is applicable to study chemical changes to minerals occurring during carbon sequestration. Through the commission of a high pressure/high temperature in-situ FTIR cell and the subsequent spectroscopic following of carbonation reactions in synthesised silicate mineral analogues, we document fundamental chemical changes occurring at the nanoscale during carbon storage. Speciation, coordination of carbonate ions to the surface of silicate mineral analogues and changes in surface hydroxyl coverage are observed and discussed, in the context of CO2 injection and dissolution/mineralisation reactions of reservoir silicate minerals.
