Carbon Capture and Storage (CCS) primarily targets carbon dioxide, but its implementation can indirectly influence the emission levels of other toxic air pollutants. While CCS is not specifically designed to remove substances like sulfur dioxide, nitrogen oxides, or particulate matter, the integrated systems often require pre-treatment steps that may reduce these contaminants. For instance, flue gas desulfurization and high-efficiency particulate filters are frequently used before carbon capture units to prevent equipment fouling and corrosion.
Furthermore, some CCS technologies involve chemical scrubbing processes that can simultaneously remove a portion of other acidic gases from the industrial exhaust stream. However, it is important to note that CCS does not replace standard air quality regulations or existing pollution control measures for non-CO2 pollutants. The primary objective remains carbon sequestration, and complete removal of toxic substances depends on the specific configuration of the capture plant and local environmental standards.
