Carbon Capture

For the wider industrial installed base, carbon capture and storage (CCS) offers a direct pathway to reduce large amounts of carbon dioxide (CO2) emitted from the industrial burning and processing of fossil fuels without major impact to the front end production process.

Carbon capture technologies typically use an amine-based solvent scrubbing system to directly absorb CO2 from the flue gas or process stream. These carbon capture systems can remove 80 to 95% of the CO2 emitted from a power plant or hydrocarbon process.

There are many technological approaches to CCS, but a common requirement for nearly all large-scale schemes is a system for transporting CO2 from capture sites to storage sites. Pipelines are the most common method for transporting large quantities over long distances.

Maintaining a very low level of water in the transported CO2 is very important. If water is present, it will react with the CO2 to form carbonic acid. While carbonic acid is relatively weak, its presence will result in corrosion of the pipeline over time. Likewise, underground storage sites may also be affected by corrosion if the stored CO2 is contaminated by moisture.

    Absorber inlet and outlet

    To optimize any type of CO2 scrubbing system, it is important to measure the CO2 levels entering the scrubber, as well as those present in the product gas stream.Changing trends in outlet CO2 levels that cannot be explained by inlet concentration changes may be an indicator of saturated scrubber media or inadequate temperature, pressure, or flow management.

    Regeneration unit outlet

    After amine or other scrubber media is regenerated, the captured CO2 stream may be monitored for impurities prior to storage or utilization.

    Transmission pipeline

    When carbon is captured as CO2, its safe transportation and utilization in other locations is critical.Although moisture is the most commonly analyzed component in CO2 streams, other impurities may also be present and must be identified.Hydrogen sulfide (H2S), methane, and even carbon monoxide concentrations may be measured.

    Underground storage

    Just like transmission measurements, impurities in the captured CO2 need to be measured.  Although levels of H2S, methane, and carbon monoxide are not likely to significantly change during storage, moisture levels can.Pipeline managers need to understand any changes in the moisture levels in order to properly manage it.
