Alternative Aviation Fuels

Question: Discuss about theAlternative Aviation Fuels. Answer: Introduction Civil aviation enjoyed very strong growth over past decade. That growth is forecast to the, continue for foreseeable future, environmental implication of that growth is proportional. Due to limited availability of AVGAS because of that its resources are reducing. Energy resources those are able to offset that trouble are renewable energy resources because of their wide availability and no or less environmental impacts. Industry that should be considered from global perspectives is aviation industry, particularly with respect to fuel supply. This report is qualitative assessments of range of the renewable fuels option for the jet aircraft end by identifying FT kerosene, biodiesel and hydrogen fuel are the most promising options. Renewable Aviation Fuels This study reviewed and identified renewable fuels option for aircrafts. The renewable fuels considered were described below-: Bio-Diesel Bio-diesel is defined as the mono alkyl ester of the fatty acid that is obtained from either etherification of oleaginous crop such as soybeans and canola/rape, or by from waste products of oil.We can use Bio diesel as kerosene extender, that means kerosene can be mixed with kerosene for aircraft use. The industrial oil and food lead research into the bio diesel as kerosene extender, is mainly particularly interested in the soybean methyl esters, which has been assessing concentrations of about 10-30% by the weight. Advantage By using biodiesel blended with kerosene can reduce carbon emissions. It is imagined but not yet confirmed that blended biodiesel In kerosene is capable to give air quality emission advantage over 100% kerosene in same way that internal combustion biodiesel gives quality air emission benefits as compare to the mineral diesels ICEs. Disadvantage There are no. of disadvantage with use of bio diesel as kerosene extender. Biodiesel blend compromise kerosene performance in very cold temperature that is encountered at the high altitude. That happens because of biodiesel blended in the kerosene raises the fuels cloud point. The temperatures at which fuel become cloudy or hazy because of formation of the micro crystal those if present can blocked fuel filters, fuel lines and plugs etc. Biodiesel comprise high proportion of polyunsaturated and unsaturated fatty acid that makes biodiesel susceptible through oxidation to the degradation, which in turns introduces possibilities of the storage problem. Fischer- Tropsch Kerosenes Kerosene can be produced synthetically by means of Fischer- Tropsch or by other synthetic fuels production process, from wide variety of the carboniferous feedstock which includes biomass. Fischer- Tropsch fuel is manufactured in three steps procedure: Syngas generation: Synthesis gas is generated by conversion of feedstock. Synthesis gas is composition of H2 and carbon monoxide. Hydrocarbon synthesis: Production of synthetic crude by catalically conversion of syngas into misture of wax and liquid hydrocarbons. It is actual step of Fischer- Tropsch synthesis. Upgrading: The mixture of FT hydrocarbons is then upgraded through the fractionated and isomerization and hydrocracking into desired fuels. Advantages Fischer- Tropsch kerosenes derived from biomass feed stocks would brings fuel cycle CO2benefits compared to the mineral kerosenes, and can also largely eliminates SOx emission since fuel is completely free from sulphur. Fischer- Tropsch kerosene is physically and chemically similar to the mineral kerosenes. As such that is broadly compatible with handling facility and, current fuels storage and notwithstanding with currently used jet engine. Disadvantage It is virtually free from sulphur and it has a very low aromatic content that leads to the lubricity poor. This trouble can be solved by means of aromatic fractions and additives. As compared to mineral kerosenes it has little bit less energy density, because it is an iso-paraffinic. The reduction in aircraft maximum range can impact on the long- haul flight. That reduction in range is relatively small and however will be the offset partially by increase in aircrafts efficiency those are predicted for continue in short term medium. Nuclear Aircraft nuclear design considers 2 design, the indirect and direct turbojets. With direct designs, air can enters through compressor one or more stages turbojets. Then it is directed through reactor cores. The air, acts as coolant of reactor, which is heated it passes through core, and then it can be directed toward turbine sections of turbojet, from there it outs through tailpipe. In the indirect design of turbojet coolant fluid is used in the closed circuit so as to enter in the reactor. Heat is transferred to the air through the heat exchangers that enters in turbojets by entering in the turbine section by passing through the compressor. Major problem with design of nuclear aircraft is that it is its safety and weight. Example, in early time a nuclear designed propulsion system was weighted about 80 tones. From which reactor weighs 5 tones and shielding weighs approx. 50 tones. Safety concern, either emission of radiation while operation, or explosion in case of accident are major concern. LiquefiedNatural Gas There is particular strategic interest in development of LNG because of its higher reserves than oil. LNG aircraft CO2 emission are approx. 25% lesser than the kerosene aircraft, although with use of bio-methanes the CO2 fuel cycle benefit could be greater. Hydrogen Hydrogen as jet fuel gives environmental benefit if it is extracted through biomass gasification or by water electrolysis process by using electricity generated from renewable energy resources. In hydrogen combustion primary combustion product is ware and secondary emission product is nitrogen oxides. Hydrogen combustion not produces harmful products like CO, SO, unburned hydrocarbon, CO2. But these are emissions of kerosene burning process. That volumetrically lower energy density clearly describes that hydrogen aircraft should accomplish with large fuel storage tank as compare to conventional aircrafts. Conclusions Biodiesel, FT kerosene and Hydrogen, these all has potential to bring saving in aviation sector non-renewable energy use. For hydrogen major research efforts has been required for production of appropriate new engine designs and airframe those appear unlikely from commercial hydrogen aircrafts are seen from several decade. For safety reason, the aviations industries are particularly resistant to unproven or new technology fuel; those provide strong commitment in favors of use of finite supply of the renewable fuel for the alternative purpose. Renewable energy resources are not limited as no-renewable energy resources like AVGAS and there is no or very less harmful environment impacts. Because of their wide availability major research is conducted on these resources mainly of hydrogen because of its high energy content and combustion kinetics. Renewable source sources could used to displace non- renewable sources.

Major Scientific Discoveries of the 19th Century free essay sample

Scientific knowledge expanded rapidly, and influenced the way Europeans viewed the world; perhaps more profoundly than at any other time in history. Among these changes was Louis Pasteur discovery of the germ, which opened up a whole new world in health care. This led to Europeans using soap and taking showers more often, a huge market for antiseptics and disinfectants opened up, new methods for food preservation were discovered and used, the invention of the refrigerator, avoiding being around people who are sick or appear to be sick, people being much more picky about what they eat such as not eating foods that were undercooked, fell on the ground, or a bug landed in it, and much more effective methods developed to prevent wide spread of disease. Another major development in 19th century Europe was thermodynamics, which investigated the relationship between heat and mechanical energy. Machines were the focal point of the Industrial Revolution. We will write a custom essay sample on Major Scientific Discoveries of the 19th Century or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Thus the efficiency of those machines became a major concern to scientists and industrialists. Charles Darwin challenged the idea of a special divine creation of each species of animal and concluded that all life had gradually evolved from a common ancestral origin in an unending struggle for survival. This completely changed the way people viewed the natural world and led to Herbert Spenser said that the human race was driven forward by a constant specialization and progress by a brutal economic struggle. The poor were the weak and the prosperous were the chosen strong. Spenser’s philosophy became known as Social Darwinism, which was very popular with the upper middle classes. It later became the justification for presumed Anglo-Saxon superiority. Many advancements in technology, medicine and human behavior occurred in Europe during this period. The 19th century gave witness to the Scientific Revolution and changed the world forever.

Where the red fern grows by Wilson Rawls Essay Example | Topics and Well Written Essays - 500 words

Where the red fern grows by Wilson Rawls - Essay Example The story is about Old Dan and Little Ann, two coonhounds bought by Billy when they were tiny puppies, how the three grow up together and help each other out on the path of life; and the life that the dogs and Billy lived with each other, and how they were always on the lookout for one another. Finally, when Old Dan dies due to injuries and Little Ann due to the grief, Billy has a revelation as he learns the true meaning of life. This paper helps to give an insight, through various examples from the book, of how Billy tried to persevere and train his dogs, and in the process, how he matured as a person himself. Thus, it helps to portray how a person must learn to accept suffering and make sacrifices before he is truly mature.   In the beginning, when Billy was a young boy, he wanted two coonhounds so badly, that he was willing to spend a good amount of time working to earn enough money in order to be able to buy them. Through a number of odd jobs, Billy is able to earn $50 to suffi ce him for the puppies. With this example, one can easily see that hard work and perseverance paid off as Billy sacrificed his time to work and earn so he could finally buy them. Furthermore, one can witness Billy working hard to train the puppies, along with his grandfather, as he taught the dogs all about racoon hunting so that they could kill enough racoons to make the family business of selling racoon fur grow and develop.

Post Employment Benefits Essay Example | Topics and Well Written Essays - 1750 words

Post Employment Benefits - Essay Example 2. We have been provided with what would be "amortized" this year (2007) towards Unrecognized Prior Service Costs, but we have not been provided with what is the actual amount pending towards UPSC. 3. We have been told that the employer's contribution would be 3% of payroll. But we do not know as to what are the company's expenses on salaries and wages. 4. We have no information regarding the number of employees involved in the scheme, their retirement dates, etc. All this information can influence the answer. So, where ever required, we have made suitable assumptions relating the above missing information. Answer 1: From the given information, if the company decides to go on with its existing (DBP) post employment benefits plan, from the information available, we can draw up an approximate pension worksheet, as follows: Items General Journal Entries Memo Record Annual Pension Expense Cash (Prepaid) / Accrued Cost Projected Benefit Obligation Plan Assets Unrecognized Prior Service Cost Balance, Dec. 31, 2006 810,000 Cr 340,000Dr (a) Unrecognized Prior Service Cost Balance, Jan. 1, 2007 --- (810,000+) Cr 340,000 Dr (b) Service Cost 88,000 Dr 88,000Cr (c) Interest Cost 81,000 Dr 81,000 Cr (d) Actual Return 34,000 Cr 34,000 Dr (e) Amortization of UPSC 21,000 Dr 21,000 Cr (f) Contributions X Cr X Dr Journal Entry for 2007 156,000 Dr X Cr (156,000 - X) Cr Balance, Dec. 31, 2007 0 (374,000 + X) Dr Note: In the above table, 1. Interest / Discount / Settlement Rate = 10% 2. Opening and closing balance of Unrecognized Prior Service Cost is unknown. (Shown as '') 3. Since the amount contributed by the employer...They do so by letting the company switch over from its existing 'defined benefits plan' to a 'defined contribution plan' to save costs. 3. The employees give up their claim on every other liability, like whatever is pending towards Unrecognized Prior service costs, what ever would be this years service cost, interest burden on what ever is pending towards 'Projected Benefits Obligation', etc. 5. Employer will contribute 3% of the payroll towards the 'retirement fund' or the 'plan assets' hence forth regardless of whatever has been accumulated in the fund, whether it is sufficient, insufficient or in excess. 6. AND hence forth, since the company moves on with a 'defined contribution plan', employer doesn't have any more liability other than payment of his annual contribution towards the fund and what ever post employment benefits are to be derived would be out of the balance in the 'fund' kept aside for that purpose. From the given information, if the company decides to go on with its existing (DBP) post employment benefits plan, from the information available, we can draw up an approximate pension worksheet, as follows: While, if the employer decides to switch over to a 'defined contribution plan' where the employer pays 3% of payroll as his contribution, the agreement being that the employees get to keep what is already in the defined benefit
