Carbon dioxide fossil fuel combustion

As pollutants go, carbon dioxide might be considered a relatively innocuous component of our atmosphere. After all, every breath we exhale contains about 4% carbon dioxide even though the inhaled air is only about 0.04% carbon dioxide. Fossil fuel combustion and natural decay processes combined with forest and grassland fires release billions of metric tons of carbon dioxide into the atmosphere annually. At the same time, trees, grasses, and other plants remove equivalent quantities of carbon dioxide from our atmosphere each year. Carbon dioxide is constantly being dissolved in and released from the ocean and other bodies of water as their temperature fluctuates. In other words, carbon dioxide is constantly being added to and removed from our atmosphere by a variety of processes, some natural and some of human origin.

Energy production and consumption pose nature into pressure and make the energy sector becomes the largest contributor of greenhouse gas (GHG) emission in Vietnam since 2010, accounting for 67%. Several emission sources of GHG could be found in a waste treatment facilities it came from (1) emission of methane (CH4, GWP 25) at landfill of mixed waste, (2) from emission of fossil carbon dioxide through the combustion of plastics and composites or supported fuels (auxiliary), and (3) from emission of nitrous oxide (NOx) during incineration/ pretreatment process, etc. 

Also, by the very nature of chemical transformations, there are almost always unused chemicals remaining. These chemical leftovers include contaminants in the raw materials, incompletely converted raw materials, unavoidable coproducts, unselective reaction by-products, spent catalysts, and solvents. There have long been efforts to minimize the production of such waste products, and to recover and reuse those that cannot be eliminated. For those that cannot be reused, some different use has been sought, and as a last resort, efforts have been made to safely dispose of whatever remains. The same efforts apply to any leftovers from the production of the energy from the fuels produced or consumed by the processing industries. Of particular immediate and increasing concern are the potential detrimental effects of carbon dioxide emissions to the atmosphere from fossil fuel combustion, as discussed further in Chapters 9 and 10. 

Fig. 6-1. The response to fossil fuel burning of atmospheric carbon dioxide. The fossil fuel combustion rate is shown at the bottom of the figure, and the calculated carbon dioxide level appears as a solid line at the top of the figure. Observed carbon dioxide values are plotted as triangles (Broecker and Peng, 1982). The observations have been normalized to preindustrial theoretical values.

About 98% of carbon emissions result from fossil fuel combustion. Reducing the use of fossil fuels would considerably reduce the amount of carbon dioxide... 

Also, all parts of society contribute to the problem. For instance, carbon dioxide emissions to the atmosphere due to fossil fuel combustion is caused 50% by industry the other parts are domestics and transport (the electric power contribution is divided between industry and domestics) (6,7). 

Carbon dioxide Natural and industrial potential carbon sources exist volcanic activity, living organism respiration, fossil fuel combustion, cement production, changes in land use. Natural CO2 fluxes into and out of the atmosphere exceed the human contribution by more than an order of magnitude. The rise in atmospheric CO2 concentration closely parallels the emission history from fossil fuels and land use changes. 

Careful monitoring of carbon dioxide during the past two decades in Hawaii, Alaska, New York, Sweden, Austria and the South Pole has firmly established that carbon dioxide is steadily increasing in the global atmosphere. This increase is due to anthropogenic activities including fossil fuel combustion. It may also be caused by altered land use management, such as, forest destruction in the tropics. 

On the global-scale, the destruction of ozone by halocarbons was addressed in the U.S. by banning chlorofluorocarbons in aerosol products. The release of carbon dioxide to the atmosphere from fossil fuel combustion wil1 continue well into or through the twenty-first century. Energy requirements of nations of the temperate zone will require combustion of gas, oil and coal and the atmospheric burden of carbon dioxide will continue to increase with uncertain consequences.

Other Gases The most extensive available data for gas emissivity are those for carbon dioxide and water vapor because of their importance in the radiation from the products of fossil fuel combustion. Selected data for other species present in combustion gases are provided in Table 5-6. 

Economic and social research on the factors which will determine future emissions of carbon dioxide. This should include the probable rise of future rates of world energy use and the future misuse of energy sources — that is, the ratio of energy from fossil fuel combustion to that from other energy sources. Also needed are better estimates of possible future changes in the areas of forests. 

Cl -1- O3 CIO + O2. 6 The gas causing an increase in the greenhouse effect is carbon dioxide released by combustion of fossil fuels. It allows most of the Sun s radiation through to the Earth s surface but, when the warm surface gives out infra-red radiation it stops this radiation from escaping into space. Hence, an increase in the concentration of CO2 in the atmosphere makes the atmosphere a better insulating (2)...

Carbon dioxide (CO2), the natural product of fossil-fuel combustion, has been recognized as the main factor for the global warming. Among the various approaches to utilize the CO2 gas, there has been a considerable interest in biological CO2 fixation as a clean and energy-efficient technique [1]. 

Despite the clear evidence of a subpopulation of individuals sensitive to near-ambient peak levels of sulfur dioxide, the two-decade-old NAAQS for sulfur dioxide has not been changed nor has a short-term peak standard been instituted. A considerably greater amount of attention has been placed on the contribution of airborne particulates, particularly those associated with sulfur oxides, to adverse health effects. The carbon-, mineral-, and heavy metal-based particles produced during fossil fuel combustion and smelting promote the conversion of sulfur dioxide to sulfuric acid. Recognition of sulfur dioxide-particle interactions comes as a result of findings garnered from a number of animal studies and the characterization of sulfuric acid, ammonium sulfate, and ammonium bisulfate associated with atmospheric particles. The importance of the coexistence of sulfur oxides and particulate matter is reflected in the...
