Oil Characterization

Workshop
The petroleum characterization method in HYSYS converts laboratory analyses of condensates, crude oils, petroleum cuts, and coal-tar liquids into a series of discrete hypothetical components. These petroleum hypo components provide the basis for the property package to predict the remaining thermodynamic and transport properties necessary for fluid modeling.
HYSYS produces a complete set of physical and critical properties for the petroleum hypocomponents with a minimal amount of information. However, the more information you supply about the fluid, the more accurate these properties will be, and the better HYSYS will predict the fluid’s actual behaviour.
In this example, the Oil Characterization option in HYSYS is used to model a reservoir fluid. The fluid is a combined gas and oil stream.

    Synthesis Oil Banana

    Purpose of this experiment is to synthesis Banana oil by mixture of the isopentyl alcohol and acetic acid . Banana oil smells like fruit mostly it smells like banana. This reasons that this compound uses in different perfume products as well as the gums for the flavor. The reaction that takes place in this experiment is a esterification. In this experiment, the carboxyl group of the acetic acid joins with the hydroxyl group of the isopently alcohol, catalyzed by the presence of sulfuric acid, through a dehydration reaction, in which water is removed. This allows for an ester bond to form in the second carbon of the isopentyl acetate (banana oil).…

    Oil Absorbed In Water Research

    The question that this experiment answered was “Does the type of material affect the amount of oil absorbed.” The hypothesis was “If a sponge is put in a container of oil, then it will absorb the most.” The independent variable was the type of material used, rag, paper towel, and sponge. The dependent variable was the amount of oil absorbed. Control variables were the same brand of the different materials used, the same batch of the mixture of paint and baby oil, and the same place. The experimental groups were the materials being placed in the oil. There were three control groups one was the sponge another was a paper towel and the last one was the rag. The procedures were that one at a time the materials were placed in the container. There are three groups, one group with the time in the oil at fifteen seconds, another group with a time limit of thirty seconds, and the last group with the time limit of sixty seconds.…

    Oil Absorbency Hypothesis

    Oil Absorbency Hypothesis

    The hypothesis for the Oil Absorbency Lab was rejected. My hypothesis was that if a person puts a sponge in materials “crude oil”, then it will absorb the most amount of oil. The data collected from this experiment rejected the hypothesis because it stated that the sponge would absorb the most oil, but the sponge did not absorb more oil than the rag. The rag and sponge’s ranges were for the first trial was 53.0g, the second trial was 51.0g, and the third trial was 46.0g and the rag. The rag and sponge’s averaged ranged scores were 51.0g, I believe this happened because the rag has more space than the sponge to hold the oil. An outside factor that may have caused this outcome could have been the amount of pressure placed on the material…

    Alien Article for Crude Oil

    Recently I have discovered an interesting fuel which humans use. It is a sludgy, black, gloopy liquid like fuel called “crude oil”. They have found it in many of the earth’s oceans and I believe it has come from many dead animals piling on top of each other but didn’t decay properly because of the anaerobic conditions making layers of rock. The heat of the rocks and the increased pressure turned the dead animals into crude oil. I have found out that they put crude oil into a machine and separate using an interesting method called fractional distillation.…

    Petroleum and Oil

    The case titled “ExxonMobil and the Chad/Cameroon Pipeline”, examines two large oil businesses merging together to finish an immense development project which spanned for approximately 25 to 30 years. In 1998, both Exxon and Mobil both respectively saw great success as major companies at the time with each company performing multi-billion dollar operations. In 1997 Exxon was achieving a large net income of $8.5 billion with revenues soaring as high as $137.2 billion, achieved a “AAA” debt rating, and also shelling out 5.4 million barrels of gasoline on a daily basis for huge profits. In contrast, Mobil thrived by building a strong reputation as well. The company saw revenues of $65 billion and achieved a net income of $3.3 billion; shelling out 3.3 million barrels of gasoline daily. In 1996, Shell, Elf and ExxonMobil signed a memorandum with the Chadian and Cameroonian governments which provided the sanctioning of a project which involved oil drilling for roughly 25-30 years. Their vision was to expand oil fields in the southern region of Chad by hauling out 300 wells of oil in the Doba Basin and as well building a 650-mile underground pipeline channel from Chad to Cameroon due to Chad being landlocked. The pipeline would move the oil to the coastline of Cameroon and be transported off to various parts of the world. The price of the development was $3.5 billion generating one billion barrels of oil. According to the World Bank, they approximated that the development would produce $2 billion for Chad, $500 million for Cameroon, and $5.7 billion for ExxonMobil and its associates. Ironically, the union of ExxonMobil was reminiscent of John Rockefeller’s Standard Oil Company which split apart in 1911 when the antitrust powers that be forced them to divide into two separate…

    The New Oil

    Water is a resource lots of people take for granted. When water starts to become more scarce throughout time, who should take control over it? Public companies? Or Private? I believe the answer to this dilemma is that public companies should mostly take control of the water system but still work with private companies to benefit the water supply the most. They should mostly control the water supply because I think that private companies won’t be able to handle the water resources properly. According to the article “The New Oil” by Jeneen Interlandi, private companies don’t understand how important the conservation of water means to the survival of the human race and all the animals and plants on earth. Wars will start because water is running out, killing millions of people. If water runs out, everyone will die, completely destroying the earth’s ecosystem because everything needs water. It is a scarce, inelastic resource that needs to be handled with the utmost care.…

    deradicalization

    As a result of the overwhelming preoccupation with uncovering the process of radicalization into terrorist activity, little attention has been paid to the related, yet distinct processes of disengagement and deradicalization from terrorism.While a variety of deradicalization initiatives worldwide are currently receiving enormous interest from afar, it is inevitable they will be subjected to intense scrutiny regarding their alleged outcomes and claimed successes. A more immediate challenge, however, is to assert some conceptual and terminological clarity. While deradicalization has become the latest buzzword in counterterrorism, it is critical that we distinguish it from disengagement and stress that not only are they different, but that just because one leaves terrorism behind; it rarely implies that one become 'deradicalized '. One of several implications arising from this distinction may be a more realistic appraisal of how our knowledge and understanding of the disengagement processes (and not undefined and poorly conceptualised deradicalization efforts) may be put to effective use in the short-medium term development of research agendas.…

    Biodiesel fuel is made from natural and renewable resources. It can be manufactured from algae, vegetable oils, animal fats, or recycled restaurant greases. Fresh soybean oil is most commonly used. In general they are made from fats and oils, which are hydrocarbons. These hydrocarbons are filtered and mixed with an alcohol, such as methanol, and a catalyst, resulting in a chemical reaction whose major products are biodiesel fuel and glycerol.…

    Petroleum

    Petroleum is formed by the remains of fossilized plants and animals that became buried in the ocean under silt and sand. It takes millions of years for its formation. We are depleting it at a rapid pace and that is why it is considered a non-renewable resource. There are over 4,000 oil fields around the world. One of the biggest oil fields is Ghawar, in Saudi Arabia. They produce about 4.5 million barrels of oil per day.…
