The super-critical CO2 experimental rig

Figure 1. The'super-critical-CO2' flow rig

The BGS Transport Properties Research Laboratory has developed a state-of-the-art flow rig, capable of testing the long-term transport behaviour of reservoir caprocks exposed to carbon dioxide (CO2). Understanding such behaviour is a prerequisite for establishing the viability of long-term storage of carbon underground.

The new super-critical-CO2 flow rig will allow testing of caprock materials over a range of basin conditions (up to 1.3 kbar at 150°C). The rig can investigate scenarios with either gaseous or super-critical CO2 as a permeant, and a CO2-saturated aqueous solution also present.

The apparatus has been designed to resist the corrosive properties of CO2, with all wetted components manufactured from titanium.
