Pore-scale dissolution of CO2Â +Â SO2 in deep saline aquifers

► Particle based solution of coupled flow, diffusive, and electrochemical transport. ► Impact of pore-space topology on the dissolution of CO2 and SO2 is studied. ► Impact of the electrostatic forces on the transport of multiple species is studied. ► Dispersion in the presence of reactions and electrostatic forces is analyzed.
