Download file to see previous pages As it has been reported that the global demand for energy is likely to be fulfilled by the exploitation and utilization of fossil fuels in decades to come, the need for developing effective systems for the capture and storage of CO2 has become indispensible (Yue 2010). While, the significance of this observation is undeniable the present systems and frameworks which are utilized extensively in the industry are inadequate and do not support the advancement of certain aims and objectives that are associated with the development of suitable technologies. As noted by Yue (2010), present solutions for solving the issue are marked by the absence of cost-efficiency, capture efficiency and conversion efficiency which is an alarming scenario for both researchers and analysts alike. This observation proposes that the technology of chemical looping combustion (CLC) and its related processes have emerged as an innovation which presents numerous prospects and opportunities for the development of energy and power-related technologies by minimizing the risks, limitations and drawbacks that are associated with the solutions that are currently and presently available within the industry. Numerous studies and researches have established that the CLC technology boosts of impressive efficiency rates for the purpose of producing electricity and hydrogen in scenarios where the system of gasification is associated and integrated within the chemical looping technology (Yue 2010). Since the inception of the innovation, empirical studies have also been able to establish the types of suitable components that should be installed within an effective CLC system to maximize desired outcomes. This aspect involves the selection of solid fuels that can be used in chemical looping in addition with the oxygen carriers which have the potential to enhance the oxidation process. Even though, these observations have revealed the possibility of utilizing an extensive range of carbonaceous fuels and carriers, the scope of this paper focuses on the process of coal chemical looping such as the coal-direct looping process and the process of syngas chemical looping. Furthermore, the paper also explores the practical applications of chemical looping combustion in organizations such as General Electric and Alstom. In conclusion the research examines the advantages, challenges and limitations that are associated with the process of coal chemical looping in the light of recent researches and studies. The application of chemical looping combustion (CLC) processes is a revolutionary advancement and innovation in the industry, as stated by Yue (2010): Chemical-looping combustion (CLC) is a new alternative to conventional combustion that prevents the CO2 from being mixed in the combustion gases. This is accomplished by preventing the air-N2 to be present in the part of the reactor system where the oxidation of the fuel takes place. (p. 527) The introduction and subsequent incorporation of chemical looping techniques and strategies was impelled by the absence of frameworks that could be applied for the separation and conversion of chemicals during the occurrence of various product-related procedures (Fan 2011). While, this observation is reflective of the traditional demands and needs which initially required the launch of chemical looping techniques, contemporary applications of chemical looping essentially aim to fulfill the need of establishing a modern, optimized and effective ...Download file to see next pagesRead More

...will revert closer to pre-industrial levels at around 350 (Hansen 2009). Coal is not only the largest reservoir for carbon dioxide of all the fossil fuels it is also the dirtiest as it pollutes the oceans and streams with chemicals including: mercury and arsenic (Hansen 2009). These are very dangerous chemicals. Hansen (2009) indicates that the UK, US and Germany are responsible for the pollution of the atmosphere with carbon dioxide with UK causing most of the pollution followed by the US and Germany. 3.4 Destruction of mountains Extracting coal from mountaintops is carried out with the use of heavy explosives.

...and used type of coal, for coke (a residue of coal used in the steel industry), electricity, and heating as well. The last of the four, anthracite coal, is the hardest, oldest and best of the four types. It is black, glossy and very hard like a rock. It has the lowest sulphur content and the highest carbon content. This is the most sought after type of coal, as it is the most valuable in terms of its lasting capabilities when burned (Speight, 2005). Although the primary use of coal is to generate electricity, coal is also used in certain plants to make chemicals, cement, paper, ceramics and other metal products. Its...

How coal is fromed
...?Coal is one of the most ancient known sources of energy in the world. It is been used almost since the beginning of the humanity. For centuries it has been vital for the mankind to sustain heat in dwellings as well as being used for cooking, making clay pots and much more. Later, with the industry development, besides being a source of energy and fuel, the coal became a vital element in steel and cement production, production of benzol, methane, tar, coke and more. Coal is one most important and used source of the energy in the world. It has been used to produce almost 40% of electricity worldwide, with some countries using it much more extensively for that purpose: produce of...

...sediments, together with movements in the earth's crust - known as tectonic movements - buried swamps and peat bogs, often to great depths. With burial, the plant material was subjected to high temperatures and pressures. This caused physical and chemical changes in the vegetation, transforming it into peat and then into coal. (World Coal Association) Coalification The quality of each coal deposit is determined by: varying types of vegetation from which the coal originated depths of burial temperatures and pressures at those depths length of time the coal has been forming in the deposit The degree of change undergone by a...

EPA estimates that over 60% of the streams located in the Central Appalachian region are compromised by the hazardous amount of toxic chemicals and heavy metals. A study done by the EPA has found levels of magnesium, calcium, manganese, dissolved solids and water hardness have increased significantly, thus greatly compromising the quality of the water to any life form around the area (Perks 3). Apart from the solid waste that create valley fills, the liquid waste that is created by water that is used to wash the coal for impurities so that it can be ready for the market. The liquid waste is a mixture of carcinogenic...

The transmission of information at chemical synapses involves the release of a neurotransmitter from a presynaptic cell, diffusion across the synaptic cleft, and binding of the neurotransmitter to specific receptors on the postsynaptic membrane to produce a change in membrane potential. In chemical synapses, there is a gap between the presynaptic cell membrane and the postsynaptic cell membrane, known as the synaptic cleft. Information is transmitted across the synaptic...

Slope mining coal
...and Number of the Teacher’s SLOPE MINING OF COAL Introduction Slope mines are used in the mining of coal and other underground minerals which are deep under the ground, due to which surface mining is unable to reach it. The term “slope mine” arises from its function as a slanting shaft or tunnel passing through the mountain down to the coal bed. The slope mine is used where the drilling of shafts vertically down through the moutain is not possible. Slope mines are mostly less deep than the mines with vertical shafts. In cases where the coal layer is near the surface of the earth, horizontal mines are bored through to access the coal easily. However, with...
