Recommended: Semi micro fractional distillation

How is this method used to help produce chemico-technical products (fuels,solvents, etc).

The fractional distillation is when the crude oil get separated to a different parts, called fractions. The fractionating column is used to separate the crude oil, at the beginning the crude oil is heated at the bottom, that makes the hydrocarbon molecules to act very fast and separates from each other. Because the fractionating column have different boiling points, the consist in the crude oil allows to be separated using fractional distillation. By starting from the bottom in the fractionating column to the top, the crude oil evaporate and its vapour allows to condense at different temperatures in the column so we can get different uses of oil like for example; fuel oil, Diesel oil, Gasoline/petrol, etc. http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/rocks/fuelsrev3.shtml

(Ke C 10,11) Refineries often use cracking to produce chemicals from oil which can be useful precursors.

Explain why we have to “Crack” long-chain hydrocarbons instead of using the products of fractional distillation directly when we manufacture plastics

Because cracking lets us turn long-chain molecules into more useable shorter ones. It always makes short-chain composites like for example ethene and propene, which have a double bond between carbon atoms. The double bond makes these composites reactive. So they can be used to make plastics. By using the cracking method it help us to manufacture plastics because if we have a long-chain molecule we can’t add then other atoms, but if we crack the molecule it help us to take the broken part and add other atoms, So take a look at the drawn example below:

...e to reduce the amount of plastics which are produced. Because plastics comes from oil and oil is a natural resource and it is nonrenewable so instead of making new produced plastics we can recycle the unusable plastics even if it is very costly because oil is more worth than money because money is man-made but oil is a natural resource it is nonrenewable so it is best to save as much oil as we instead of using it to produce plastics which we still have on earth and which can’t be destroyed. So the best way to plastics is recycling.

Where does petroleum come from and how do we extract it?

    There are a number of points at which Fox talks about how fracture fluid contains a mix of over 596 chemicals and how they are undisclosed because they are considered proprietary. Not only do individual states mandate the full public disclosure of fluid additives, but the federal government does as well, and the Occupational Safety and Health Administration (OSHA) requires that this information be kept at all well sites (Energy In Depth). Since then, it has been proven that fracture fluid is comprised almost entirely of water and sand, and typically containing less than one percent of an average of 12 components, most of which can be found around the house. Additionally, oil and gas is not the only use of fracturing, as it has also been used to access sources of water and geothermal

  • Comparing Cyclohexane And Toluene

    After comparing the class data that consists of the percent compositions of Cyclohexane and Toluene using the different types of distillation, I think the most efficient method is packed. The 4th fraction for packed contained an average of 6% Cyclohexane and 94% Toluene while the unpacked contained 4.35% Cyclohexane and 95.65% Toluene. The simple contained 3.35% and 96.63%. The packed is the most efficient, because the glass beads that provide more surface area for condensation. The data also shows that the unpacked is more efficient than simple distillation. This can also be because of the long tube in unpacked that provides more surface area for more than one condensation like the simple distillation does.

  • Pros And Cons Of Recycling

    1810 Words  | 4 Pages

    The words ‘Reduce, Reuse, and Recycle’ are what a person chants if someone mentions the word recycling. Nicks J defines recycling as ‘[T]he processing of waste materials in order to make them reusable” (11). Individuals who recycle are not just throwing papers in green bins, or cans in blue; in fact, they are helping the environment more than they can imagine. People who want to preserve and protect their planet take the initiative to recycle waste materials. Rather than throwing away old plastic or glass bottles, aluminum cans, and certain types of paper, one can simply recycle them, and they will go through a cleaning and the remanufacturing process to be remade into a new usable item.

    First step to produce polyethylene is to obtain the ethane from the ground. Ethane can be obtained either by extraction from natural gas or from crude oil using a process called fractional distillation (AUS-e-TUTE n.d.; University of Washington). Fractional distillation is a process that separates the various components of crude oil, in this case, to obtain ethane.

    The modern world of today runs on fossil fuels with crude oil being the live blood of industrialized countries. Though much of the twentieth century old was plentiful easily acquired and low in cost it has only been in the past thirty years that we have seen oil prices rise substantially. This can be attributed to many different reason. These price changes have challenged the industrialized world to become more creative with their techniques of both acquiring oil and using it.

    Many people believe that we should not recycle anymore, but this is not the case. We, the people of the world, need to continue to recycle because we do not want our children to grow up in a world where there are no certain species of animals due to recycling failures. We also do not want our children to grow up thinking that it is okay that they throw their garbage on the ground, and not have to pick it up. We need to teach our children that they need to take care of the earth that they are living on, because they only get one. Recycling is one of the most beneficial environmental issues that we have here on this earth. Recycling saves energy, limits pollution and supports several environmental factors of the economy. “In 2003, the savings from recycling 54 billion aluminum cans exceeded the energy equivalent of 15 million barrels of crude oil- or the amount of gas the U.S. uses in one day,” according to the U.S. Environmental Protection Agency. The EPA estimates that 200 million gallons of used oil are not disposed of properly, and if we were to dispose the oil properly then we could keep the oil from polluting the ground and the fresh water source. According to E. Takatori, “… While on-going societal regulation treats material recycling as the dominant cycle, the properties of recycled plastic remain the most port

    The worst imaginable environmental catastrophe that could occur in Maryland has just become a reality. The lifeblood of Southern Maryland's Watermen has been forever affected. The ecosystems of the Patuxtent River and Chesapeake Bay have been irreversibly contaminated. The Three Mile Island and Chernobyl Nuclear Accidents have affected the world ecosystems; but the Chalk Point oil spill has reached us here in Southern Maryland. The ethical considerations with generating electricity from fossil fuels, specifically oil, has a profound impact on us all. We all use electricity to make our lives easier and more productive. By using this electricity have we given our permission for the oil companies free reign in order to provide us with the service we demand?? Are we just as responsible for the oil spill as the corporate leaders who run the companies? As citizens we are in a position to develop and enforce regulations to protect ourselves. Do we also protect the environment; or is the environment just something for us to use? These and many other moral dilemmas exist for modern man.

  • Persuasive Speech On Recycling Plastic

    There are many people in the United States today that are unemployed due to our economy. Therefore, recycling could create jobs for those people. Recycling is a complex process that needs multiple workers. First, the plastics and other recyclable items have to be collected. Next, the plastics have to be separated into categories. This might seem simple but it is a three step process. The first separation is made directly by the codes on the plastic. The second separation makes smaller categories of like plastic materials. The third separation is made by determining certain properties of the plastics that are comparable. The categories are then shredded, sanitized, and then melted down. Finally, the factories then mold the plastic into direct items or palletize them for use in the future (Manrich, 9). The recycling companies could make their money by making deals with major corporations. For example, they could collaborate with Pepsi by creating their plastic soda bottles. The recycling companies would be able to sell and create these bottles for cheap since they do not have to pay for the materials to make them. Also, they use less oil than a plastic production factory would use. Thus, it is a cheaper way to create new plastic items. Therefore, there are endless possibilities that allow the recycling business to

    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.
