With the development of the global economy and human society, energy consumption has been increasing. However, this consumption also brings serious environmental issues, 

one of which is the emission of carbon dioxide. Carbon dioxide is a greenhouse gas that causes global climate change and has significant impacts on the environment and human 

health. Therefore, the recovery and utilization of carbon dioxide have become urgent issues.

There are mainly two methods for carbon dioxide recovery: physical absorption and chemical absorption. Physical absorption involves using physical methods such as compression 

and adsorption to recover carbon dioxide. Chemical absorption, on the other hand, utilizes chemical reactions to capture and recover carbon dioxide. Both methods have been 

widely applied in practice.

The recovery of carbon dioxide can play a role in many fields. For example, in the chemical industry, recovered carbon dioxide can be used to manufacture chemicals. In oil fields, 

recovered carbon dioxide can be injected underground to enhance oil recovery. In the beverage manufacturing industry, recovered carbon dioxide can be used to produce 

carbonated beverages.

Furthermore, the recovery of carbon dioxide can help reduce atmospheric pollution. Many countries are taking measures to reduce carbon dioxide emissions, such as adopting 

low-carbon technologies and improving energy efficiency in factories and power plants, as well as using renewable energy sources. These methods can reduce carbon dioxide 

emissions but cannot eliminate them completely. Therefore, the recovery and utilization of carbon dioxide provide another effective means to reduce atmospheric pollution.

In conclusion, the recovery and utilization of carbon dioxide have become important measures to reduce atmospheric pollution and address global climate change. By adopting 

appropriate recovery technologies and methods, carbon dioxide can be converted into useful resources while reducing environmental burdens.
