In particular, such as power plants, chemical plants, mining plants, the issue of carbon dioxide emissions has become the focus of people's attention. Through the analysis of the geochemical cycle of carbon, it can be clearly known that carbon is exchanged and recycled in the natural cycle, including both long-term and short-term processes. In order to mitigate carbon dioxide emissions, this article takes an in-depth look at carbon capture and separation methods and analyzes in depth how to store carbon. The first is carbon capture and storage, which involves different processes including pre-combustion, post-combustion and oxy-combustion (Leung et al., 2014). Pre-combustion capture typically occurs in coal or natural gas, and post-combustion carbon capture (PCC) technology is a relatively mature technology in power plant systems. Oxygen combustion is also used in various power plants. In order to store carbon, the carbon is separated after capture. The main methods are absorption, adsorption and membrane separation. The commonly used solvent for absorption is monoethanolamine (MEA). The adsorption is generally attached to the surface of the adsorbent during the carbon dioxide adsorption process. The latest way to separate carbon is to use membrane adsorption with high permeability and selectivity to carbon dioxide.Say no to plagiarism.

Physical carbon storage methods and technologies typically store carbon dioxide in different geological structures, such as abandoned oil and gas reservoirs, deep-sea storages, and saline aquifers. Photosynthesis plays a key role in the carbon cycle, so afforestation not only stores carbon, but also increases its ability to sequester it. Ocean carbon sequestration is also a giant container for storing carbon based on photosynthesis. Pilot experiments are currently underway to test whether this method is effective. Microalgae and cyanobacteria have high carbon sequestration capacity that also relies on photosynthesis, both of which are too costly. In conclusion, each carbon capture and storage method is promising for climate mitigation, but there are many limitations, such as cost and immature technology, etc. . Physical methods are relatively immature and play a minor role in some industries. Lack of government incentive mechanism, expensive to operate. Blue bacteria and algae are also studied. Carbon sequestration is a beneficial method for mitigating change.
