The role of chemistry in solving environmental problems.
Chemical processes play an important role in environmental problem. The vast majority of harmful emissions from power plants, transportation, industrial and agricultural enterprises are products of different chemical reactions: oxidation (combustion), rehabilitation, expansion, and so n. Understanding of these reactions helps engineers make the right decisions to reduce or eliminate damage to the harmful effects.
The source of the harmful effects on nature is, and chemical industries. By this time in the environment thrown around 3 million new chemical compounds, which nature has not adapted. It should be noted, however, that the use of chemistry is essential to solving environmental problems. The chemical industry produces a range of reagents, adsorbents, ion exchange resins and other substances, without which no treatment of wastewater and gas emissions.
An integral feature of the chemical industry is to increase the degree of the complex use of raw materials. On the basis of the laws of chemistry can solve many environmental problems not only in the chemical, and other industries. The most promising method of solving environmental problems is to create friendly and non-waste technological processes.
Air protection.
Products of fuel combustion.
The main anthropogenic atmospheric emissions of pollutants caused by burning fossil fuels in power plants, boilers, industrial furnaces and internal combustion engines, as well as the processing of ore and produce various chemical products.
The total anthropogenic emissions on our planet in the 70s were (tones / year): dust and soot-(8-16) 108, carbon monoxide-(2-3) 108, sulfur-(8-15) 107 nitrogen oxides (4 - ^ 8,5) 107. The bulk of emissions come from power plants, metallurgy, oil extraction and refining, transport. A significant part of harmful atmospheric emissions caused by burning fuel. The main source of pollution is carbon monoxide transport. |
