Introduction:

 

This is a report regarding a research that we as groups at our college have conducted successfully on the types of fuel oils which exist in our world and their properties, characteristics as well as applications in our world. We have conducted experimental tests in a lab to find out the different properties which may lead us to guess the type of fuel oil that we are working on according to certain chemical and physical properties which exclude this type of fuel oil from others existed. Luckily we were able to find out the type of fuel oil we were working on by comparing our data and findings to the real properties of all different types of fuel oils that are existed. So let’s take a look first on the background of fossil fuel and the types of fuel oils existed, their characteristics and applications in real life and then talk about the negative impact of fossil fuel on the environment and the living organisms and then mention the alternatives to fossil fuels and finally discuss our experimental test and findings.

People around the world use fuel for energy resources. The non renewable ones which people often use to produce energy are called fossil fuels. It fuels formed by natural processes such as anaerobic decomposition of buried dead organisms (Fossil fuel - Wikipedia, the free encyclopedia 2013). These fuels have unfortunately become so essential in people’s lives and millions of houses and businesses around the globe mainly depend on them for energy. There are many different types of fossil fuels existed in the world. Mainly speaking there are three different types including natural gas, coal and crude oil. A look back at the history of fossil fuels we can easily figure out that places where little animals and populated plants which died and decayed in the underground were believed by scientists to be the home of fossil fuels. This was mainly due to the creation of layers of organic materials which happened when their dead bodies decomposed.

Fuel oil is often referred to the fraction of fuel which is obtained during the distillation of petrol or during the residue of petrol as well. It is a liquid petroleum product which is often burned in a boiler to generate heat and eventually power. One type of fuel oil is diesel. It is made through a long chain of hydrogen. Another type is residual fuel which is less useful because it is so viscous and that it has to be heated using a very special heating system before use and it contains relatively high amounts of pollutants particularly sulfur. The common use of this type of oil is that it heats homes and businesses and fuels trucks ships and some cars. A small amount of electricity is produced by diesel, backup fuel for peaking power plants in case the supply of natural gas is interrupted and the main fuel for small electrical generators (Fuel oil - Wikipedia, the free encyclopedia 2013).

Jet fuel or aviation turbine fuel is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to straw-colored in appearance. Jet fuel is a mixture of a large number of different hydrocarbons. Jet oil is commonly used for commercial aviation. It is also used in civilian turbine-engine powered aviation is Jet B which is used for its enhanced cold-weather performance (Jet fuel - Wikipedia, the free encyclopedia 2013).

Turbine oil is often called and referred to any oil that are often found in bearings and machines. Its Common Uses are to lubricate the bearings and auxiliary machinery and synthetic turbine oils are used in control systems of high-power steam turbines (Turbine Oil definition of Turbine Oil in the Free Online Encyclopedia 2013).

Gear oil is lubricant oil that is often made specifically machineries. Its Common Uses are mainly for transmissions transfer cases and differentials in automobiles, trucks, and other machinery. It is also used to protect the gears and usually is associated with a strong sulfur smell (Gear oil - Wikipedia, the free encyclopedia 2013).

Transformer oil or insulating oil is usually a highly-refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers and high voltage capacitors fluorescent lamp ballasts (Transformer oil - Wikipedia, the free encyclopedia 2013).

 

 

 

Testing description:

API gravity: after check the temperature by thermometer, use a funnel and pour the sample into the hydrometer cylinder until it is about ¾ full. Then put a hydrometer with an (SG rang 0.8 to 0.9), let it go you can give the hydrometer a small spin to help it stabilize. Finally take reading from hydrometer and make calculation to calculate API gravity. Do it for three times to get more accurate result.

Cloud point: pour the oil sample into the test jar, put the jacket with the test jar and sample into warmest section of the cooler (1.8C), let sample cool. After check the sample every (1C) until found a cloud or haze at the bottom of the test jar. Finally if you see a cloud forming write dawn the temperate. Do it for three times to get more accurate result.

Pour point: pour the first oil sample into the coldest section of the test jar cooler (-34C) and let the sample cool all the way to (-34C) until become solid. Then put the sample into the next section (-18C) and check it every (3C) by taking it out of the copper jacket and tipping it over and watch it for 5 seconds. If the oil starts to flow, you have reached the pour point.

Viscosity: placed 2 viscometers with oil sample into oil path then when oil bath and samples are at the correct temperature you may start talking viscosity measurements by use a stopwatch to time how long it takes for the oil to flow from the top line to the bottom line.

Flash point: First, put the sample on Cleveland Open Cup Apparatus which consist with the cup, heating plate, test flame applicator and heater. Then expose fire into sample until sample start catch the fire. Finally write down the temperate.

Refractive index: After put sample in microscope, later when light passes through a medium, some part of it will always be absorbed. This can be conveniently taken into account by defining a complex index of refraction.

BECAUSE BOTH RESULTE ˂ 2% THAT MEAN BOTH RESULTE ARE PRECISE

Discussion:

Many reasons showed that the sample we got is mostly like turbine oil. As we know the flash point of turbine oil is (207C) and the results showed us that the flash point of the sample we’ve got is (224C) taking under consideration the human error. In addition, the TAN number of turbine oil is (0.08 mg KOH/g) and the results showed us that the TAN number of the sample we’ve got is (0.09 mg KOH/g) which shows us how close the tows of them are. Another point that supports our finding that API gravity of turbine oil is 31 which are close to our sample 32.

 Why we didn’t choose other oils to be our sample? The first thing we noticed the huge different between the pour point of gas oil, transformer oil which are (0C and -62) and our sample which is -30C. Second point that support our belief that our sample are not jet fuel or gear oil is the TAN of both of them (0.015 mg KOH/g and 0.5 mg KOH/g) because that far away  from TAN or our sample which is (0.09mg KOH/g).           

There are problems that faced us while we were working in our literature research one of them was not having an accurate numbers while surfing the net which didn’t match our results so we take ASTM book as one reference and working based on that. Second problem we faced is how to find the cloud point of our sample, this problem we can’t solved because sample out of equipment rang. In addition to that we had to repeat the TAN test twice because we didn’t find the answers in the computer, finally lab assistant take a hand on that. Overall it was a very successful experiment.

Combustion the fossil fuel has a huge negative impact in the environment; it is the main reason of releasing the greenhouse gasses into the atmosphere which leads in causing Air and water pollution which can damage the environment and the human. However there are harmless alternatives to fossil fuel. They are: solar energy (energy can produce energy by heating in solar panels), wind energy (which helps in producing electricity by using the wend in moving the turbines), the hydroelectric power (rivers can help in creating electricity), geothermal power (producing energy by the hot springs steam) and the waves power (the ocean waves can also help in rotating the turbines to produce energy).

 

Conclusion:

First of all, I would like to say that it was a great opportunity to work on one of the most important part of our major and a very cooperative team. It was great to have a chance to take responsibility in making different types of researches that links to our previous knowledge and solving the problem we faced due the experimental individually. Finally, after compeers our test results with the literature search table (witch shown in appendix 1), there is no doubt that our sample are turbine oil.
