Crude Oil Crude oil is a complex mixture of hydrocarbon molecules formed over millions of years when the remains of microscopic sea creatures trapped in sediments were converted by heat and pressure into crude oil. The most abundant of these mixtures are the ones containing hydrogen and carbon only. These hydrocarbons can take on a number of different forms, i.e. alkanes, alkenes and alkynes. They vary in size and shape and viscosity. By manipulating these chains of hydrocarbons you can create any number of useful substances as they are very adaptable. However there are lots of compounds that also contain some of the following; oxygen, sulphur or nitrogen. The purer hydrocarbon compounds are the most required for these produce a higher temperature when they are burned which is the primary use for it as it generates an excess amount of energy when burned and therefore is a useful fuel. The other compounds with sulphur or nitrogen also have a high energy when burned but they have a negative side-effect as they make sulphur dioxide and nitrogen dioxide when burned and these compounds contribute towards acid rain. Crude oil has to be refined by fractional distillation to separate the short productive hydrocarbon chains from the longer, less useful ones before the compounds can be put to good use. Fractional distillation is a technique that relies on the difference in boiling points of the chains of hydrocarbons to separate them. It is so specific that it can separate the substances from each other even when there is only a small amount of difference between the boiling points of the substances. The crude oil is heat... ... middle of paper ... ...ne, which are used to manufacture chemicals. Or the residual from the distillation tower is heated 482°C, cooled with gas oil and rapidly burned in a distillation tower. This process reduces the viscosity of heavy weight oils and produces tar. The other method of cracking is called Catalytic Cracking and it uses a catalyst to speed up the cracking reaction. Catalysts include zeolite, aluminium hydrosilicate, and bauxite. The hydrocarbons (only from the oil fraction) are heated in the same way but the catalyst speeds up the reaction by lowering the boiling point of the substance and allowing high molecular mass alkanes to break into many low molecular mass alkanes and some alkenes. Because the bond breaking happens randomly, many different forms of the substances are made, i.e. cyclo or branched isomers.

The reason for this report is to increase the reader’s knowledge on the Alberta Tar Sands, which will allow them to create their own opinions on the situation. It is a very pertinent issue in politics and will have a very large effect on the carbon emissions of Canada. Also, I wanted to further my understanding of the Alberta tar sands and learn the side effects of the tar sands. How the tar sands are different from other oil and energy procurement methods and which method is more energy efficient? Would the construction of the Keystone XL pipeline in the United States be an intelligent way for the US to involve itself in the tar sands? I wanted to answer these questions by knowing the real facts about the tar sands versus what the oil companies are telling the consumers. The ability to assess the entire situation will allow both the reader and I to formulate our own opinions about the tar sands and whether the extraction of oil at the tar sands should continue.
After the oil/gas mixture is drawn from the ground, it is then stored into a storage tank and allowed to rest for a while. Then the gas is piped off to a set of distillation columns to clean up the ethane. In order to activate the chemical reaction necessary to separate the ethane, a thermal cracking unit (a sort of long heated tube) i.e. a plug flow reactor is used. After a series of distillations, ethylene exits the tube.
Experiment to Find Out Which Fuel Produces Most Energy. Aim = == My objective in this piece of coursework is to determine which of five fuels produces the most energy and if the energy production relates to the amount of carbon..
An important mark in history is a point when there is a change of great significance. Big business grew to sizes wielding incredible power during the late 19th century. The power of these businesses would be expressed in the form of monopolies that would allow them to dominate their specific area of the market, if not multiple areas of the market. John D. Rockefeller’s Standard Oil was a prime example of a large monopoly over oil and everything that was needed to produce it and distribute it. His control over oil would eventually lead to the need of enacting laws of regulation by the government. Standard Oil would initially draw the attention of the State of Ohio and eventually the Supreme Court. The dissolution of the companies that made up the monopoly of Standard Oil would come with the passage of the Sherman Anti-Trust Act of 1890 (The Editors of Encyclopædia Britannica).
I think this will happen because there are more bonds in the large hydrocarbons, so it will take more energy to break them all. By having more energy acting on the hydrocarbon, means when the bonds are broken more energy will be released (an exothermic reaction). This reaction will heat the water. As the larger hydrocarbons release more energy than the smaller ones (i.e. methane) it means less hydrocarbons have to react to produce the same amount of heat energy, so less fuel is consumed.
The Pacific Oil Company was formed in 1902 and had been the leader in the manufacturing of a petroleum product Vinyl Chloride Monomer (VCM). This product was Pacific Oil's major product line and was the main component to the manufacturing of plastics, used in many products. In 1979, Pacific Oil had landed a major contract with reliant and had over the years establish a great working partnership. The Reliant Corporation was one of Pacific’s largest and most valued customers and Pacific Oil Company wanted to renegotiate their current contract with the Reliant Corporation, with the goal of extending before it expired. Pacific’s negotiation team, Jean Fontaine, Marketing Vice President for Europe with Paul Gaudin, Marketing Manager of VCM along with representatives Frederick Hauptmann, Senior Purchasing Manager and Egon Zinnser, Regional VP for European operation from The Reliant Corporation, where to spend nearly two year working through the extension of the contract. In the end, the contract settlement was down to a final item that Pacific was not happy about, that may my then loose the extension altogether.
The statement ‘Canada oil sands are much more of a blessing rather than a curse’ is not true because the disadvantages of oil sands outweigh the advantages. For this reason, this paper aims at indicating points against the statement. To understand the defects of oil sand exploration in Canada, one has to delve into the explanation of what oil sands are as well as how the entire process of mining and refining and thereafter, determine the disadvantages based on socioeconomic factors, environmental factors, as well as the infrastructure and energy required for its production.
Full combustion should generate two products only: carbon dioxide and water vapour. Hypothesis Within a molecule there are bond energies that hold the atoms together. When the fuel combusts, a chemical reaction takes place, this breaks the bonds, this requires energy, and makes new bonds, this gives out energy. The energy differences between the two tell us how much energy was given out or taken in. We can show this in a graph.
Like oil, natural is a product of decomposed organic matter, usually from ancient marine microorganisms left on the bottom of bodies of waters mixed with mud, silt, and sand on the sea floor, gradually becoming buried over time. Since it is sealed off in an oxygen-free environment and exposed to increasing amounts of heat and pressure, the organic matters undergo a thermal breakdown process that converts it into hydrocarbons. The lightest of these hydrocarbons exit in the gaseous state under normal conditions and are known collectively as natural gas.

The process need toluene and hydrogen as a main reactor. Then, toluene and hydrogen are converted in a reactor packed with catalyst to produce benzene and methane. This reaction is exothermic and the operating conditions are 500 0C to 660 0C, and 20 to 60 bar of pressure. This process begins with mixing fresh toluene with a stream of recycle unreacted toluene, and the mixing is achieved in a storage tank. Then, the toluene is pumped to combine it with a stream of mixed hydrogen and fresh hydrogen gas. The mixture of toluene and hydrogen is preheated before it is introduce to the heater or furnace. In the furnace, the stream is heated to 600 0C, then introduced into the reactor. Basically, the main reactions occurs in the reactor.
» Downstream: significant refineries incorporate unrefined petroleum preparing and transport of items to retail outlets.
The oil refinery converts crude oil into valuable products and supplies. These products are made and sent to many countries abroad, in which are transported on land or along rivers and canals. Crude oil is then arranged and categorized into segments by fractional distillation. Raw crude oil, or unprocessed crude oil, is not normally beneficial in most industrial applications. Low sulfur crude oil has been valuable as a burner fuel to construct steam for the force of seagoing vessels. The lighter elements have the ability to construct explosive and dangerous vapors in the gas tanks. There are extremely hazardous, and are often used in war ships. The remaining hydrocarbon molecules are filtered from crude oil and used towards lubricants, feedstock, plastics, and fuels.
