Conducting Batch Reactions at Relevant Geologic Carbon Sequestration Conditions
2 Dec 2014Geologic carbon sequestration (GCS) is needed to mitigate global warming caused by increased atmospheric CO2 concentrations. For safe and efficient GCS operations the geochemical reactions with CO2-brine-rock under relevant GCS conditions needs to be studied. In this application note, CO2-brine-biotite interactions were studied and fibrous illite formation was observed after reaction for only 3 hours. The fibrous illite detached and released into solution after longer reaction time, indicating potential permeability decrease in the aquifer, as fibrous illite can clog the pore spaces affecting further CO2 injections.

PumpsLaboratory pumps are devices used to move liquids and gases by vacuum or positive displacement. The pressures/vacuums generated are determined by the type of pump used. High vacuum pumps include diffusion, ion, roots and turbopumps; for primary/medium vacuum applications see rotary vane pumps, scroll & diaphragm pumps. For the positive displacement of liquids explore a range of syringe and peristaltic pumps, as well as fluid aspirators.
