On the artificial carbon dioxide source in the chemical industry
In today's world, the chemical industry is complicated, and the artificial carbon dioxide source is quite important to scholars. In the chemical industry, there are various activities, which are all the reasons for the generation of carbon dioxide.

First, fuel combustion is a common source of carbon dioxide. Chemical operation requires energy to supply it. Fossil fuels such as coal, oil, and natural gas are often selected for energy. When these fuels are burned in chemical furnaces and kilns, carbon and oxygen are synthesized, resulting in carbon dioxide. Take a large chemical refinery as an example. In the daily refining process, a large number of petroleum products need to be burned to maintain the reaction temperature and mechanical operation. The amount of carbon dioxide emitted is quite considerable.

Second, the specific process of chemical production is also a source of carbon dioxide. For example, in cement manufacturing, the core step is the decomposition of calcium carbonate. Calcium carbonate is calcined at high temperature and decomposed into calcium oxide and carbon dioxide. In the chemical industry, many similar chemical reactions generate carbon dioxide due to the characteristics of raw materials and reaction mechanisms. In the ammonia industry, in the gas-making stage, coal or natural gas is used as raw materials and reacts with water vapor. Although the purpose is to produce hydrogen, there are also by-products of carbon dioxide in the process.

Furthermore, the treatment of chemical waste also involves the generation of carbon dioxide. Some chemical wastes are rich in carbon compounds. When treated by incineration or other means, the carbon element oxidizes and becomes carbon dioxide that escapes into the atmosphere. Even in landfills, under specific anaerobic environments, microorganisms decompose carbon-containing waste and slowly produce carbon dioxide.

In summary, there are many man-made sources of carbon dioxide in the chemical industry, and their impact on atmospheric carbon dioxide concentration should not be underestimated. Therefore, the chemical industry and scientific researchers should seek effective measures to reduce carbon dioxide emissions and find green and sustainable development paths to meet the needs of the environment.
