Carbon Negative: Processes that remove more CO from the atmosphere than they produce, actively benefiting the climate. Net Zero: Emissions are still generated but offset through removal, aiming for a net-zero total. This may include CO and other greenhouse gases. Carbon Capture, Utilization, and Storage (CCUS): Technologies to capture CO emissions and repurpose or store them. Applications include: Pre-combustion: Conversion of fuel into a gaseous mixture of hydrogen and CO2. The hydrogen is separated and can be burnt without producing any CO2; the CO2 can then be compressed for transport and storage.This technology is particularly suitable to be applied to integrated gasification combined cycle (IGCC) power plants. Post-combustion: Separation of CO2 from combustion exhaust gases. CO2 can be captured using a liquid solvent or other separation methods. In an absorption-based approach, once absorbed by the solvent, the CO2 is released by heating to form a high purity CO2 stream. This technology is widely used to capture CO2 for use in the food and beverage industry. Oxy-fuel combustion: These processes use oxygen rather than air for combustion of fuel.This produces exhaust gas that is mainly water vapour and CO2 that can be easily separated to produce a high purity CO2 stream. Carbon Storage Techniques: Geological storage in depleted oil fields, saline formations, or coal seams. Technologies include low-temperature separation, adsorption, and membrane separation. Carbon Capture: Solvent absoprtion, membrane separation Case Study: Ammonia Production (Haber-Bosch Process) reducing CO emissions during ammonia production. Mineral Carbonation: Reacting CO with minerals to form stable carbonates, with ongoing research to improve reaction rates. Made with nCreator - tiplanet.org
