Numerical investigation of the partitioning phenomenon of carbon dioxide and multiple impurities in deep saline aquifers

Abstract

The partitioning behaviours of CO2 with three kinds of common impurities, i.e., N2, CH4 and H2S, in the formation brine are investigated by numerical simulations. The results indicate that the effects of N2, CH4 or the mixture of N2 and CH4 at the same concentrations are generally similar. The leading gas front is usually made up of less soluble impurities… (More)
