With a smaller need of gasoline, the mining of fossil fuels could be reduced thus preventing from the nonstop execution of our minerals. Besides, hybrid cars also can reduce current pollution as they emit less harmful and toxic gaseous from the exhaust. Miller(2004) claimed that hybrid cars also produce low sound which means less noise compared to the regular combustion engine cars. Engineers use electrical motors as they meant to work with a low sound. Moreover, in terms of energy, hybrid cars have higher efficiency compared to conventional and full electric cars as it uses kinetic energy from braking to form electric energy then, charging the battery simultaneously.
Process Support recommends lowering the amount of fresh acid consumed to get closer to the spend target. Noticeably, there is very little reduction in acid strength from A train to B train. This indicates that there is not much additional reaction happening between the two. Process Support will contact Stratco to determine what could be causing this phenomenon. In general, the unit consumes more acid than required (91 target spend strength vs. 89 technical target spend strength) because controlling the series acid flow is a manual operation (see Figure 4, pg.5).
Should renewable energy replace fossil fuels? Amer Sharbek Intro- In this essay presentation I will be discussing about renewable energy replacing fossil fuels, also what this replacement can do for the whole world and what it can not. I will present two perspectives and explain them fully, I will also state counter arguments for both perspectives. Opinion- My opinion is that renewable energy should replace fossil fuels because fossil fuels has damaged the environment causing many problems (e.g. Climate Change).
Two significant facts about the mercury compound found in Thimerosal make it safer; the incredibly small concentration of mercury, and the use of the ethylmercury. Firstly, the highest concentration of thimerosal that is used in vaccine preservations is only 0.01%, meaning that only 25 micrograms of mercury are present per 0.5 mL dose.That is extremely inconsequential when compared to the real sources of mercury pollution; air and water emissions from gold-mining Chloralkali plants and the discharge of dental amalgams. This small amount of mercury is also less likely to make its way into the environment in the first place, due to the nature of vaccines as a product to not be so easily discarded in the environment, in contrast to mercury products such as batteries. Secondly, the use of methylmercury means that subsequent pollution of the environment with the drug will not lead to bioaccumulation, (the presence of large amounts of pollutants in top consumers of the food chain) in ecosystems. This is because, unlike other types of mercury compounds like methylmercury, ethylmercury can clear through the bloodstream extremely quickly, meaning that pollution of the environment with Thimerosal will not lead to negative effects on the tertiary consumers of ecosystems (such as large fish).
Biodiesel is much safer than diesel from petroleum when biodiesel is escaped to the surrounding environment; moreover, it is much less inflammable as biodiesel’s flashpoint is 130°C as compared to petroleum diesel which is only 52°C. As a result, biodiesel is low-risk to be stored, kept, and delivered (U.S Department of Energy). Trans-esterification reaction can be illustrated as following: Triglyceride + Alcohol → Methyl esters (biodiesel) + Glycerol (Vegetable oil) (Methanol) FIGURE 1.1 Typical trans-esterification reaction is carried out to produce Biodiesel (AOCS Lipid Library) Furthermore, biodiesel can be produced from the tobacco seed and soya bean which tobacco seed oil reduces the
the average fuel economy for a gas truck is around 14mpg. Along with the poor fuel economy, the gas that goes through the truck does not burn as clean. When the gas does not burn as clean, that means that it puts out more pollution than a diesel engine. A diesel engine also has 25-30% better fuel economy that a gas engine. With the 25-30% better fuel economy, a diesel engine can deliver much more fuel economy that electric hybrids.
Electric cars are safer than gasoline powered cars. When you buy an electric car the government pays people near to, seven thousand dollars if you buy an electric car as a bonus. Gas cars increase global warming, and are bad for the environment spreading pollution, while electric cars do not. As I have said maintenance cost for electric cars are better than gas powered cars. Electric cars have a lot less parts than a gasoline car.
Our Earth is made up of matter that is everything that has mass and occupies space. The formation of matter is because of energy and one of the examples of energy is the renewable energy. Renewable energy is energy that sources from natural resources that is constantly renewed on a human timescale and cannot be exhausted. Renewable energy is classified into five components which are hydro, wind, biomass, solar and geothermal energy (refer to Figure 1 in Appendix 1). The first type of renewable energy is the hydro energy.
Future possibilities and environment benefits, there’s a study that it lessen the air pollution by using it. Abundant domestic production, increased resale value and more affordable maintenance. As evidenced in the Environment Protection Agency, natural gas as the cleanest fossil fuel was used in many ways to help reduce the emissions of pollutants into the environment. Burning natural gas than other fossil fuels emits fewer harmful pollutants and increase the reliance on potentially reduces emission of those many harmful pollutants. The use of natural gas does not significantly contribute in the formation of the smog as it emits lower nitrogen oxide and doesn’t have particulate matters.
The problem is that the world is a very massive place, where we need a lot of energy to fulfil the basic needs of our lives. Through the years we have been presented with several different alternative energy source options, as the energy sources like fossil fuels works against the environment. Nuclear fission is one of the alternative energy sources which is considered to be the future energy source of the world, but just like any other things nuclear fission has several disadvantages and advantages, but it is our responsibility as a society to weigh those implications and come up with a solution which supports the world for the better. Nuclear fission is one of the things which still remains to have an uncertain future which is due to two
This means that n-butanol will have less tendency towards cavitation and vapor lock problem, which can eliminate the need for very special blends during the summer and winter months as the gasoline. As the heat of vaporization of butanol is less than half of that of ethanol, an engine running on butanol should be easier to start in cold weather than one running on ethanol or methanol. In addition, the auto-ignition temperature of the n-butanol is lower than ethanol or methanol, which also results in less ignition problems at cold start or low load conditions. As butanol has a very low vapor pressure point and a high flash point, it is a much safer fuel to use in high temperatures (134). One advantage of butanol over ethanol is that it is much less anhydrous, which greatly reduces the risk of water contain absorption by the fuel, with a higher latent heat of vaporization, butanol is expected to have lower indicated specific fuel consumption.
The natural gas use has pros and cons as anything in this life. The natural gas has many advantages. It is less harmful than oil or coal. It causes less damage to the environment compared to oil and coal. It has less carbon emission because it is made of methane gas.
