Top Gas Recycling Blast Furnace CO and H2 content of the top gas has a potential to act as reducing gas elements‚ and therefore their re-circulation to the furnace is considered as an effective alternative to improve the blast furnace performance‚ enhance the utilization of carbon and hydrogen‚ and reduce the emission of carbon oxides. In Top Gas Recycling Blast Furnace‚ oxygen

SCI204 Section G Spring 2007 A Janice Webster Subject: Emission Testing April 22‚ 2007 Introduction With this paper I hope to gain a better understanding of emission pollution and the emission testing process. With my research and my visit to the local Clean Air Car Check site‚ I have compiled information that will prove valuable. I will define emission pollution and the major contributors. I will answer the why we have to emission test. I will also take you through the testing process

Emission Control Techniques 1. INTRODUCTION The need to control the emissions from automobiles gave rise to the computerization of the automobile. Hydrocarbons‚ carbon monoxide and oxides of nitrogen are created during the combustion process and are emitted into the atmosphere from the tail pipe. There are also hydrocarbons emitted as a result of vaporization of gasoline and from the crankcase of the automobile. The clean air act of 1977 set limits as to the amount of each of these pollutants

4Car carried out real-world fuel economy tests on eight low-emissions cars and all failed to meet the official figures. Three cars were as much as 10mpg short of the published fuel consumption rates. The tests examined the Golf Bluemotion‚ Skoda Fabia Greenline‚ Mini Cooper D‚ Honda Civic Hybrid‚ Toyota Aygo‚ Ford Focus Econetic‚ Fiat 500 1.2‚ BMW 118d‚ all of which are regarded as low emissions/fuel economy models. The Golf Bluemotion got closest to its official figures in the 4Car tests

As a policy maker concerned with correcting the effects of gases‚ and particulates emitted by and local power plant. 1. What two policies could you use to reduce the total amount of emissions? Two of the most common methods of controlling and reducing emissions are incentives and penalties. These incentives and penalties can affect everyone from the general public to large‚ multinational companies. 2. Why do you think they each would work? Those who use more green methods in their everyday

every family in United States has at least one. Statistics say‚ that 89% of Americans have a passenger vehicle in a household‚ and that’s an amazing thing‚ but‚ this privilege leads to more serious problems than not getting somewhere on time. Car emissions produce three types of carbon - Carbon Monoxide (CO) and Carbon Dioxide (CO2) and hydrocarbon (CH4) - which are traumatizing both our health and the environment. By itself‚ carbon isn’t a harmful element‚ but one of its characteristics is easily

Emission Spectroscopy The purpose of this lab was to see that when elements are heated‚ they may enter and excited state. We proved this by doing a flame test. During Part A‚ we used a spectroscope where all of the colors are arranged for you; whereas in Part B‚ we could see and make the colors ourselves and get a more accurate reading of the flames. We had specific elements we were told to put on the wire loop‚ and when we did that we saw different color flames come out of the Bunsen burner. That

INTRODUCTION Radioactive emissions are electromagnetic radiations which occur due to the spontaneous disintegration of unstable nuclei. Natural elements with atomic number greater than 83 and isotopes of some lighter elements are found to be radioactive. They are categorized as alpha‚ beta and gamma radiations. Alpha particles are positively charged helium-4 nuclei ‚ beta particles are high energy-high speed electrons while gamma rays unlike alpha and beta radiation have no mass and charge and

400-F-92-007 Automobile Emissions: An Overview Cars and Pollution Emissions from an individual car are generally low‚ relative to the smokestack image many people associate with air pollution. But in numerous cities across the country‚ the personal automobile is the single greatest polluter‚ as emissions from millions of vehicles on the road add up. Driving a private car is probably a typical citizen’s most “polluting” daily activity. Sources of Auto Emissions The power to move a car comes

For the observed 15-keV peak in X-ray energy‚ various models5‚6 give a competing picture of the discharge process‚ with the length of the gap between the separating faces of the tape being 30 or 300 mm at the moment of emission. The intensity of X-ray triboluminescence allowed us to use it as a source for X-ray imaging. The limits on energies and flash widths that can be achieved are beyond current theories of tribology.
