CO2 Capture 

Capture, transportation and geologic storage CO2 involve many kinds of technology. Most of the efforts have gone into enhancing the efficiencies in the separation techniques for other common industrial emissions gases such as CO2s. These include various “capture” technologies. The capture processes consist of three groups of approaches depending on the industry process or specifics as related to a particular type of power plant.

The flue-gas resulting from the combustion of a fossil fuel is then passed through columns that remove CO2. Post-combustion separations take CO2 in solution for its removal by adsorption or absorption. It is used in PC plants and NGCC plants. It is well-suited for use in a retrofit environment.

Syngas is mainly produced by mixing carbon monoxide and hydrogen with steam and either air or oxygen. Afterward, the carbon monoxide is then transformed into CO2 via a “shift reactor”. This CO2 may then be separated in order for the H2 to become power or heat. Specifically, this technology can be well utilized to develop IGCC power plants.

Instead of air, it burns the main fuel and gives off a flue gas with 80% of carbon dioxide and much water vapor. Then, this flue gas cools down and generates condensation of water vapors leaving clean stream of CO2. The production of oxygen from air requires additional equipment.

The technology used for capturing CO2 has a great deal of importance when it comes to minimizing negative impacts associated with releasing CO2 into the atmosphere, however such technologies are also accompanied by their unique set of potential environmental and operational risks. First, the lowering of CO2 levels released into the environment that contributes to global warming, increases in temperature, severe weather disasters like floods, and sea-level elevations are a significant advantage. This is how the technology reduces the amount of the greenhouse gas in the atmosphere by retaining CO2.

Nevertheless, similar to any other risk, Carbon dioxide capture also poses certain hazards such as leakages and escaped captured gas which might cause contamination to human life and the surrounding atmosphere. Transport and storage of captured CO2 should be closely monitored to ensure no unwanted side effects are generated. The operational energy and resources needed for the setup of CO2-capture plants also result in various environmental implications including increase in energy consumption, additional water consumption and extra land requirement.

Therefore, during implementation of this technology safety, careful monitoring, and regulation should be put in place so that overall it benefits the environment more than posing risk to it. As the technology advances it is necessary to address these risks and curb their occurrence to promote responsible and sustainable use of this technology.
