In the context of the limitation of global warming, geological storage of acid gases is one of the main options retained to reduce anthropogenic gas emissions to the atmosphere The work presented here documents the reactivity of a carbonate rock in the presence of a gas containing CO 2 and co-injected gases: 4% SO 2 , 4% O 2 , 4% N 2 and 6% Ar representative of oxycombustion flue gas before any purification (eg. desulfurisation) process. The study is based on experiments conducted in batch reactors simulating the interactions occurring between the rock and acid gases that would be injected in a geological storage context. It shows that the main mineral transformations of the rocks are due to the co-injected gases SO 2 and O 2 despite their low concentration (less than 4%). These transformations should have different impacts on the petrophysical properties of the rocks such as porosity and permeability. |
