CO2bearing

CO2bearing is an adjective used to describe substances, fluids, or environments in which carbon dioxide (CO2) is present at notable levels. It can indicate dissolved CO2 in a liquid, a CO2-rich gas phase, or CO2 that is chemically bound within minerals or structures. The term is used across disciplines such as geology, chemistry, engineering, and environmental science.

In geology and geochemistry, CO2bearing conditions occur in hydrothermal systems, magmatic exhalations, and metamorphic environments. CO2 is released from rocks and melts or exsolved from fluids, where it can influence mineral stability, metal transport, and fluid chemistry. Carbonate minerals and rocks may be described as CO2bearing because their composition involves carbonate groups that incorporate CO2 in a bound form. CO2bearing fluids play a key role in processes such as mineral precipitation, decarbonation reactions, and volcanic outgassing.

In industry and energy, CO2bearing streams appear in natural gas processing, where CO2 is removed to meet pipeline specifications, and in carbon capture and storage schemes that aim to reduce CO2 in exhaust gases. In the beverage industry, CO2bearing liquids are carbonated, providing effervescence and acidity.

Measurement and terminology commonly involve assessing CO2 partial pressure, dissolved CO2 concentrations, or the amount of CO2 bound in minerals. Techniques include infrared and mass spectrometry analysis of gases, as well as aqueous phase measurements and mineralogical assays.

Overall, the concept of CO2bearing centers on the presence and forms of carbon dioxide within a system, with relevance to carbon cycling, resource processing, and environmental management. See also carbon dioxide, carbonate minerals, and gas processing.
