Using Clean Coal Technologies to Reduce Air Pollution

Using Clean Coal Technologies to Reduce Air Pollution ASDF SCI/275 September 4, 2011 Kristal Davis Fadtke Using Clean Coal Technologies to Reduce Air Pollution Air pollution is of pronounced concern in the media lately. Some of the effects of air pollution include the increase of carbon in the atmosphere which contributes to the global warming effect. The effects have been felt with record temperatures on the east coast and in the Midwestern United States this summer. One major contribution to the pollution is the use of coal to generate electricity. Approximately 50% of the power in the United States comes from coal fired electrical generation plants (UCSUSA, 2009). A typical 500 megawatt generation plant burns 1.4 million†¦show more content†¦This system does require a large footprint to install, but it does produce a saleable byproduct. Nitrogen oxides are removed in a combination of ways (Sen, 2010). Figure one is a chart of the different ways this is done. Typically one technology is not used but a combination of them. As shown in the table, not all of the technologies are as effective as those to remove sulfur oxides , thus a combinational approach is used. One of the more impressive developments in clean coal technology has been the fluidized bed technology (Berg amp; Hagar, 2007). This technology has been in development since the 1980s and represents a great leap forward in the clean burning of coal. This technology allows the burning of coal with high sulfur content with little to no pollution (Berg amp; Hagar, 2007). The country Turkey has been developing the technology to work with their low quality coal resources as well as different biomasses including olive cake (Eskin amp; Hepbasil, 2006). The use of this technology permits greater generation of electricity with the lower quality fuels that are available in Turkey (Eskin amp; Hepbasil, 2006). The emissions are greatly reduced by the introduction of limestone into the fuel prior to the combustion chamber (Berg amp; Hagar, 2007). This neutralizes the majority of the acidic compounds produced during combustion. This technology also creates more heat with less fuel allowing for lessShow MoreRelatedA Major Area China s Air Pollution Effects On The Environment1568 Words   |  7 Pages A major area China s air pollution effects is the environment. With this in mind a way the pollution damages the environment is through acid rain (Air pollution in China). Sulfur dioxide and nitrogen oxides go high into the atmosphere to combine with oxygen to form the heavy pollutant known as acid rain (epa.gov). Acid rain easily dissolves in water, and when mixed with other pollutants in China s atmosphere, can contaminate the soil and water sources. One-third of China s water is unusableRead MoreCoal-fired Power Plant 1433 Words   |  6 Pagesstorms, droughts, etc. Along with the hostile environment, the human beings are in danger of the spreading disease, such as malaria. Coal-fired power plant generates 44 percent of the electricity; however, it is considered the biggest air polluter in the United States and one of the biggest factors in causing global warming. The greenhouse gas emissions from the coal-fired power plants are threatening the human health and the ecosystems. Fortunately, the U.S. Supreme Court upheld the authority ofRead MoreEnergy Consumption and Air Pollution1033 Words   |  5 Pagesexplain some of the relationships between energy consumption and air pollution. Personally, when I first started thinking about the topic, I thought I already had the answers. The equation was pretty simple and did not take much thought: higher energy = higher air pollution. This thought was incorrect, as I quickly found out. The very first website looked at showed that over the last thirty years, energy consumption and air pollution do not always go hand in hand. However, in some places throughoutRead MoreWhy Coal Is Responsible For Destroying T he World1725 Words   |  7 PagesRoman Empire, and indeed probably long before then, coal has been used by humans as a source of heat, providing many advantages over wood, charcoal and other fuels. However, it wasn t until the introduction of the steam engine that coal became a major part of shaping the world. Fueling the industrial revolution, the high energy concentration of coal made it the standard source of everything from trains to power plants. Coal companies claim that coal, though not perfect, is the best source of energyRead MoreThe Effects Of Global Warming On Our Economy1090 Words   |  5 Pagesmyth anymore, is affecting our economy, health and our future aggressively. The need to reduce pollutant emissions is now something urgent and an important commitment for all the nations. Natural disasters, virus and diseases are consequences of changes of temperature, the emissions of carbon gases weaken the ozone layer, water and food pollution. According to the World Health Organization, environmental pollution produces more than seven million of deaths every year. The global warming has been causingRead MoreCauses And Consequences Of Climate Change1334 Words   |  6 Pagescurrent conditions. Countries like the U.S. should set an example for everyone else by enforcing strict regulations on emissions and investing in clean energy sources to prevent further pollution of the planet and extreme weather cases directly linked to climate change. There are many causes of climate change, Current power plants burn fossil fuels like coal, oil and natural gas to generate electricity, however it is known that the burning of these fuels are dangerous and are a huge part of climateRead MoreDont Be Mean, Keep It Clean Essay1405 Words   |  6 PagesPollution. Many people know what this term means in the aspect of how it negatively affects the lives of human beings. However, many people generally don’t care about this problem (Buc hanan and Horwitz). Pollution is a serious problem that deserves to have immediate action done to prevent it. This issue has ruined the lives of many people, especially the elderly and young children (Bily 42, 43). Pollution is a deadly and lethal problem, but can be fixed by passing new laws, having people conserveRead MoreThe Effects Of Air Pollution On The Climate And Civilization Essay1571 Words   |  7 PagesImagine walking outside and not being able to breathe the air because it is too toxic; imagine if severe weather conditions, such as droughts and heat waves was the everyday norm. If action is not taken to reduce the amount of pollution humanity emits into the air, there will be detrimental effects on the climate and civilization. For instance, air pollution harms the health of people, causing respiratory issues, and air pollution negatively affects the climate, causing global warming. Both issuesRead MoreEpa s Clean Power Plan1717 Words   |  7 PagesMemorandum From Harshit Jayaswal Date October 07, 2015 Subject Briefings on EPA’s Clean Power Plan: How state emission budgets were established, and legal (reasonableness and fairness) issues. This memo is my interpretation on the readings of EPA’s clean power plan specific to how state budgets where established and legal issues emphasizing the fairness and reasonableness towards the states. 1.0 Overview The clean power plan was adopted by the EPA (U.S. Environmental Protection Agency) on AugustRead MoreRenewable Energy : Global Warming And Pollution1070 Words   |  5 Pagesconcerned with global warming and pollution. The use of fossil fuels has increased pollution in the United States from 2013 to 2014 by 3.4%. The public pressure to address this energy crisis has lead Germany to decrease their use of fossil fuels. Even so, they are still â€Å"recording modest economic growth of 1.5 percent, breaking a traditional pattern in which nations see their energy use fall only during recessions,† said Melissa Eddy from The New York Times. Using renewable resources is undoubtedly
