Depending on CO2 capture processes or hydrocarbon sources, fuel gas from boilers can be accompanied with impurities which could be co-injected in a geological storage. These gases, such as SOx, NOx, or oxygen could interact with reservoir fluids and rocks and well materials and could affect the safety of the storage. However, there are currently only few data on the behavior of such gas mixtures, as well as on their chemical reactivity, especially in the presence of water. The purpose of this paper is to develop experimental and analytical protocols in order to acquire new thermodynamic data on SO2 and NO under geological conditions of pressure and temperature using Raman spectrometry.
