Modelling of the CO2 process- and transport chain in CCS systems-Examination of transport and storage processes

This work presents an approach for the examination of a system consisting of a power plant, capture unit, transport system and CO2 storage facility. A number of typical problems are shown, with focus on the examination of thermodynamic behaviour of the captured CO2 in a pipeline followed by a well in a saline aquifer storage site. It is shown that, under special conditions, the combination of a CO2 pipeline and a well down to a saline aquifer will not work due to phase changes and pressure conditions, which would lead to operational problems or at the very least to partial destruction of either the pipes or the sedimentary storage rock.
