IMPACT OF IMPURITIES ON CO 2 STORAGE IN SALINE AQUIFERS: MODELLING OF GASES SOLUBILITY IN WATER

Abstract : Flue gas captured contains different impurities (N 2 , O 2 , SO 2, NO etc) and their concentrations depend on the capture process and the industrial sector. Moreover, the presence of impurities may change the thermophysical properties of the stream and therefore impact the conditions of CO 2 storage. The aim of the paper is to investigate the solubility in water of carbon dioxide and some chosen impurities. In this work VLE calculations using a geochemical model (Corvisier, 2013) and two group contribution (GC-PR-CPA (Group Contribution-Peng Robinson-Cubic Plus Association) (Hajiw, 2014 and Hajiw et al., 2015) and E-PPR78 (Qian et al., 2013) equations of state) models are compared.
