Factional Distillation of Crude Oil Essay Example for Free

Factional Distillation of Crude Oil Essay This process is called fractional distillation. You basically heat crude oil up, let it vaporize and then condense the vapour The various components of crude oil have different sizes, weights and boiling temperatures; so, the first step is to separate these components. Because they have different boiling temperatures, they can be separated easily by a process called fractional distillation. The steps of fractional distillation are as follows: 1. You heat the mixture of two or more substances (liquids) with different boiling points to a high temperature. Heating is usually done with high pressure steam to temperatures of about 1112 degrees Fahrenheit / 600 degrees Celsius. 2. The mixture boils, forming vapor (gases); most substances go into the vapor phase. 3. The vapor enters the bottom of a long column (fractional distillation column) that is filled with trays or plates. The trays have many holes or bubble caps (like a loosened cap on a soda bottle) in them to allow the vapor to pass through. They increase the contact time between the vapor and the liquids in the column and help to collect liquids that form at various heights in the column. There is a temperature difference across the column (hot at the bottom, cool at the top). 4. The vapor rises in the column. 5. As the vapor rises through the trays in the column, it cools. 6. When a substance in the vapour reaches a height where the temperature of the column is equal to that substances boiling point, it will condense to form a liquid. (The substance with the lowest boiling point will condense at the highest point in the column; substances with higher boiling points will condense lower in the column. ). 7. The trays collect the various liquid fractions. 8. The collected liquid fractions may pass to condensers, which cool them further, and then go to storage tanks, or they may go to other areas for further chemical processing.

Trumps Changes to Transgender Bathroom Rules

Trumps Changes to Transgender Bathroom Rules The Proposal for Transgender Bathroom Conversion Now that the Trump Administration has withdrawn Federal enforcement of the transgender bathroom order, it is up to each State to decide what course of action to take, if any (Hersher, Johnson, and para 4-5) It is evident by the number of lawsuits filed against the Federal Government that the constitutionality of Obama’s Executive Order is in question. Recently, the Supreme Court postponed hearing a case involving a Virginian transgender high school’s student, partially due to President Trump’s announcement. The details of the case involve a transgender student, who was already using the boy’s bathroom, but pressure from parents and others forced the school district to change its policy and deny the student’s ability to use the boys’ bathroom. (Liptak, para 2-5). The school adopted a policy that states all students must use the bathrooms/locker rooms according to the gender on their birth certificate and a private bathroom/locker room would be provided for transgender students. The boy sued under protections outlined in the fourteenth amendment stating he was refused civil rights because of his gender. In light of the recent withdraw of Obamaâ₠¬â„¢s order by the Trump Administration, the Supreme Court decided to send the case back to the appellate court of origination for its further review. In August, the Supreme Court decided (5 to 3) that while the student’s case proceeds, temporarily, the school is not compelled to let the student choose his bathroom (Hersher, Johnson, para 17). Besides the lawsuits sparked by the transgender bathroom issue, many religious organizations and activist groups have also voiced concern over the issue. North Carolinians objected so loudly that State legislatures refused to override state laws that stated people had to use the bathroom of the gender corresponding to their birth certificates. In return, the Justice Department sued the State of North Carolina for circumventing the ordering in this manner (Hersher, Johnson, para 11). Other states and communities passed similar laws or already had them in place prior to the order. When there is this much opposition and prejudice it usually stems from a gross misunderstanding of the situation In order to produce any meaningful solutions to this problem, it is paramount to educate the public about the medical realities of hermaphroditic conditions and elicit empathy to replace the anger this subject has released. Once Americans understand that in many cases being transgender is a choice the person’s doctor made for them at birth, it is possible more people will understand the bathroom issue more readily. It is also meaningful to illustrate the costs associated with converting schools to standards acceptable to the entire community, not just the transgender group. A three step plan is proposed that incorporates educating the public about intersex conditions, developing a realistic budget for schools to accommodate transgender bathrooms, and organizing a vote on the issue once the public is better informed.   Many people are opposed to the transgender bathroom because they lack an understanding of the medical issues involving intersex children and the path in life they face. It is difficult for most people to ever imagine having an intersex condition or having a child with a gender identity problem. Educating the public through public service announcements may be an effective way to approach this problem. If more people understood that in some cases, what has happened to an innocent baby at birth should not be the cause of persistent suffering psychologically and physiologically to have a Male XY genetic marker with a vagina. The prejudice transgender people encounter is widespread and educating the ignorant tends to abate some of the prejudice. The transgender community should consider eliciting a well-known or at least well-spoken spokesperson in order to start the process of educating the massed about the transgender plight. The second part of the plan involves preparing budget estimates for school conversions needed to accommodate transgender students. Safety of students seems to be one of the primary concerns of opponents to the bathroom issue, so privacy is of utmost priority. Based on ideas currently being discussed within the Sarasota School District, schools would provide a private, unisex bathroom for transgender students and partition locker rooms to provide a private space there as well. It is currently not known how many specialty unisex bathrooms each school will provide; however, for purposes of this analysis, it is assumed that one per school will be built out. The budget line items represent the total cost of each subcontracted task. For instance, the drywall line item indicates the total cost to partition the locker rooms/private changing areas. Even though not all of the districted schools may have locker rooms, for purposes of this cost illustration, it is assumed each school will requir e the build out. Once the public is sufficiently educated and the costs to convert the schools are properly relayed to the public, it will be time to organize a vote on the issue. Even if Trump rescinded the Federal Executive Order, States must remain concerned and prepared for a ruling by the Supreme Court that may ultimately force State school districts to comply with the initial order after all. In the event this happens, at least the public will be more educated and costs will be spelled out so that voters can make a rational, rather than emotional, decision. It must be emphasized that currently the Transgender Community does not seem to have a ‘famous’ person for their cause. A movement does not move very far without a leader. In the event the State and its voters or the Supreme Court decide to proceed with establishing policies for transgender bathroom availability, it is important to describe the costs that will be associated with revamping schools to fit the new policies. In order to illustrate the cost per school and the impact to the over school district, Sarasota County School District will be used as an example. It should be kept in mind that if legislation impacts all school districts statewide, a further cost analysis will need to be performed. The following budget is based on estimates obtained from local contractors based on a price for completed jobs (Daniel’s Plumbing, Jimenez Drywall). Based on the cost budget analysis, the cost of school bathroom/locker room conversions equal approximately $759,500, or $17.70 per registered student (SSD, Student Enrollment Charts). If the proposed idea of adding unisex bathrooms and converting current locker room space to include a partitioned area wi th showers is acceptable, the costs per student are low enough to justify the conversion.  If more build out is required, this budget analysis will need to be revised to take into consideration any changes. Based on empirical evidence (verbal survey of students from various SSD schools), approximately 0.1% of registered students, or approximately 429 children may be affected by an intersex condition or are transgender. The cost of conversion per transgender child, divided over the 13 years the child is assumed to attend SSD school, equals approximately $136 per child: this amount is rather a small amount to pay for the safety, security, and well-being of all students concerned. It should be noted; the costs contained herein estimates and are for illustrative purposes only.   The time is now for the Transgender movement to strive to educate the public more on the issues that affect them in an effort to reverse some of the prejudice that exists today. It seems imperative for the group to organize and delegate a leader to champion their cause. (Maybe Obama’s free?). Once organized, the group needs to decide how to educate the masses. Next, the group needs to formulate what bathroom arrangements are acceptable and provide a plan that includes cost estimates based on a per child basis in order to make acceptance of any changes more credible. The final phase is for the group to get petitions circulating to get the issue on a ballot and get the voters to approve its proposition. Many movements take years to accomplish their goals: Just think about how long it took women suffragettes, gay right activists, or civil rights leaders to accomplish their goals. The Transgender movement received a head start when Obama made the nation aware of one of its issues; however, the movement needs a powerful leader and some organizational zeal to accomplish its goals.

The Future as Portrayed in Brave New World :: Brave New World

The Future as Portrayed in Brave New World     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚      Aldous Huxley’s Brave New World opens in a technically advanced future world. In the beginning of this book, we see the Director of World Hatcheries lead the new hatchery students on a tour of a Conditioning Center in London where babies are produced in bottles and pre-sorted to determine which class level they will be born into. These class level range from Alpha-plus, the highest level, to Epsilon-minus, the lowest. There are no parents, and babies are conditioned from birth to learn certain behaviors. All diseases have been eliminated, and when people are feeling down, they just take soma, a wonder drug. Also, people are conditioned from birth not to love one person, so there is no marriage and most people have many lovers. There is no God; instead, Henry Ford is worshipped as the god Ford. Another accomplishment of this society is the elimination of aging. Bernard Marx has unorthodox viewpoints and is outcast as an eccentric. He likes being alone, but in this society being alone is discouraged. His isolation from society has made him very different from everyone else. His only friend is Helmholtz Watson, an accomplished intellect who writes government propaganda. Watson has grown war of life as it is, and his supervisors have him under close watch. Two co-workers are discussing Lenina Crowne, another worker, in a changing room. They act as if she were property, able to be bought and sold. Bernard is disgusted by this, so he decides to ask Lenina to go to a Savage Reservation in New Mexico. Bernard visits the Director for permission to go. The Director tells a story of when he went to a Savage Reservation with Linda, a pretty colleague. During their visit,Linda was lost, and the Director had to leave. So Bernard and Lenina go to the Savage Reservation, which is inhabited by Indians. They quickly find Linda among the Indians. At first they do not realize who she is, but she explains what happened. Linda is aged and obese. Also, Linda has a son named Jo hn who is the Director's child. John is educated and mature, having read Shakespeare (forbidden in civilization). Bernard takes the two back to London for study. Once back, Linda takes too much soma, so she falls into a coma. John is displayed by Bernard, who becomes a hero.

Revised Paper On German Modernism -- essays research papers

The Significance of Modernity Throughout time, nations have attempted to become independent from one another by discovering means, which would help their citizens experience more fulfilling lives. The dilemma that troubled each of these countries is whether or not innovations, in technology and society, led to a higher quality of life. Modris Eckstein and Marshall Berman examine both, the damages and benefits of modernity. Eckstein looks at individual changes that lead to the overall acceptance of modernity. He examines Germany, and how the lives of every citizen was altered following the revolutionary changes of the first half of the 20th century. Marshall Berman, on the other hand, assesses modernity as an all-encompassing characteristic of certain societies. He analyzes whether or not large-scale changes that societies made, improved the well being of their inhabitants. Rites of Spring, by Modris Eckstein, gives an overview of all the modifications Germany experienced, in the first half of the 20th century. Eckstein considers these individual alterations to be an attempt, by German society to modernize itself. General beliefs in German nationalism, and the treatment of homosexuals, are two of the several topics Eckstein uses to describe the aforementioned change in German livelihood. These two subjects encompass Ecksteins belief of a national German movement towards a unified culture. â€Å"It is a book about the emergence, in the first half of this century, of our modern conscious? At the turn of the century Germany was a divided nation that did not have a sense of national pride. In the forthcoming years, the convictions of all German citizens changed and the nation became unified. Eckstein attributes this massive modernization of German nationalism to the ongoing threat of war. The citizens of Germany relinquished their internal feuds, and centered their attention on the enemy outside of their borders. German focus changed abruptly because their newfound enemy was Russia and Great Britain. To the German people an assault by Russia and England was an attack on all forms of German livelihood. â€Å"We are defending in this moment all that is German Kultur and German freedom? Therefore, all German citizens came together in support of their brethren and decreed their approval of foreign bloodshed. Along with a new sense of nationalism, Eckstein believes accepta... ...o gay, or what a homo? The turning point of my approach, towards homosexuals, came when I met a guy named Adam. Adam enlightened me by explaining the true aspects of homosexuality. He also informed me that my vocabulary was hateful. After that day I came to understand that individuals who deplore homosexuals or use derogatory language are no different than those who are racists. Unfortunately, large portions of Americans do not hold the same stance. For this reason I can relate my modernist perspective to that of Eckstein’s. Individually, some people have changed their opinion of homosexuals, but the nation as a whole has done little to accept their lifestyle. Lastly, I can also relate to Marshall Bermans attitude towards modernism. I believe that in certain societies one can notice a general trend towards modernist behavior. It is my belief that one can observe this in modern day Germany. As opposed to the conservative regimes of the 30’s and 40’s, Germany presently lives in one of the world’s most progressive societies. This is a perfect example of Berman’s argument because the German people came together and implanted their newfound convictions into their everyday way of life.

Beowulf - His Last Words :: Epic of Beowulf Essays

Beowulf - His Last Words In the society in which the poem Beowulf takes place, war and kingship are normal factors in daily life. Beowulf's world is a very violent society with wars as a dominant part of daily life. Dragons and monsters are a constant threat to the Danes and the Geats. Warriors are a necessity to this war-like society. Beowulf is a hero and an example of a great warrior. He fights against monsters. In the section of the poem we are about to discuss, Beowulf is ready to fight a dragon with his thane Wiglaf. He is going to fight a dragon . Beowulf has no fear of the dragon, because he has fought many enemies that were much more ferocious. For example one of Beowulf's great battles is the fight with Grendel. No one other than Beowulf is brave enough or strong enough volunteer to fight Grendel. We are now about to enter a new age of Beowulf's life. With all his great achievements, he finally becomes king of his homeland: Geatland. Even in his old age, his code of honor still obligates him to fight against an evil, fiery dragon. For fifty years he has governed his kingdom well. While Beowulf is governing, the dragon "...kept watch over a hoard, a steep stone-barrow" (Norton 55). Under it lays a path concealed from the sight of men. Over centuries no one had disturbed the dragons kingdom until one day when a thief broke into the treasure, laid hand on a cup fretted with gold This infuriated the dragon. "The fiery dragon had destroyed the people's stronghold, the land along the sea, the heart of the country" (Norton 57). Wiglaf is the only person who stays with Beowulf to serve his lord and to fight the dragon. Everyone else becomes cowardly and runs into the forest to hide from the dragon. It turns out that Beowulf's sword can not even penetrate the dragon. The dragon gets the best of Beowulf, he "...seized all his neck with his sharp fangs: he was smeared with life-blood, gore welled out in waves" (Norton 62). Wiglaf, then, summons his wits and they killed the dragon: "The wound which the dragon had dealt him began to burn and swell; at once he felt dire evil boil in his breast within him"( Norton 62). Our hero is finally defeated. Even though he is seriously injured, he still had the strength to break the fifty foot dragon in half.

Information Security Essay

Information Security is a fundamental function of any organization expecting to be competitive in the global market. As more and more developing countries make the leap into capitalism, competiveness will only become more essential. With Asian nations like China, Korea and India stepping up to make their presence noticed taking more of the market share than ever before other organizations must remain competitive which means keeping their piece of the pie safe and secure. Organizations’ proprietary information if left unsecure could mean loss of their competitive edge. In the IndustryWeek. com article by, â€Å"Manufacturers Must Think Virtually to Ensure Data is Protected† Chris Benco contends; â€Å"Data is what all manufacturers rely upon, and with the ever-increasing influx of it, companies need to ensure that it is protected in the event of a natural disaster, human error or other problems. With this heavy reliance on data to maintain day-to-day operations, manufacturers cannot afford to overlook data protection as it is the key in maintaining production, optimizing productivity and guaranteeing profit. Information security though takes on another aspect when you consider an often over looked key element of corporate information. We think of information security in terms of protecting what is on paper and in data bases, but knowledge is much harder to nail down. Knowledge, information that is stored in the minds of the organization’s personnel is just as important as any other data or product information and should be gathered and stored just the same. As we could see in the reading material for this case assignment there are many methods for obtaining, sharing, and storing knowledge information. Some such methods were discussed by Ann Field in her article â€Å"Locking Up What Your Employees Know†. The step according to Ms. Fields are to first Create a knowledge profile, then foster mentoring relationships, encourage communities of practice, ensure that passing knowledge on is rewarded, Protect people’s privacy, and decide whether you’re interested in recorded knowledge as well.

Compare and Contrast the Reasons Essay

Suppose you are taking a course on 19th-century America, and the instructor hands out the following essay assignment: Compare and contrast the reasons why the North and South fought the Civil War. You turn on the computer and type out the following: The North and South fought the Civil War for many reasons, some of which were the same and some different. This weak thesis restates the question without providing any additional information. You will expand on this new information in the body of the essay, but it is important that the reader know where you are heading. A reader of this weak thesis might think, â€Å"What reasons? How are they the same? How are they different? † Ask yourself these same questions and begin to compare Northern and Southern attitudes (perhaps you first think, â€Å"The South believed slavery was right, and the North thought slavery was wrong†). Now, push your comparison toward an interpretation—why did one side think slavery was right and the other side think it was wrong? You look again at the evidence, and you decide that you are going to argue that the North believed slavery was immoral while the South believed it upheld the Southern way of life. You write: While both sides fought the Civil War over the issue of slavery, the North fought for moral reasons while the South fought to preserve its own institutions. Now you have a working thesis! Included in this working thesis is a reason for the war and some idea of how the two sides disagreed over this reason. As you write the essay, you will probably begin to characterize these differences more precisely, and your working thesis may start to seem too vague. Maybe you decide that both sides fought for moral reasons, and that they just focused on different moral issues. You end up revising the working thesis into a final thesis that really captures the argument in your paper: While both Northerners and Southerners believed they fought against tyranny and oppression, Northerners focused on the oppression of slaves while Southerners defended their own right to self-government. Compare this to the original weak thesis. This final thesis presents a way of interpreting evidence that illuminates the significance of the question. Keep in mind that this is one of many possible interpretations of the Civil War—it is not the one and only right answer to the question. There isn’t one right answer; there are only strong and weak thesis statements and strong and weak uses of evidence. Let’s look at another example. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. â€Å"This will be easy,† you think. â€Å"I loved Huckleberry Finn! † You grab a pad of paper and write: Mark Twain’s Huckleberry Finn is a great American novel. Why is this thesis weak? Think about what the reader would expect from the essay that follows: you will most likely provide a general, appreciative summary of Twain’s novel. The question did not ask you to summarize; it asked you to analyze. Your professor is probably not interested in your opinion of the novel; instead, she wants you to think about whyit’s such a great novel—what do Huck’s adventures tell us about life, about America, about coming of age, about race relations, etc.? First, the question asks you to pick an aspect of the novel that you think is important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write: In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore. Here’s a working thesis with potential: you have highlighted an important aspect of the novel for investigation; however, it’s still not clear what your analysis will reveal. Your reader is intrigued, but is still thinking, â€Å"So what? What’s the point of this contrast? What does it signify? † Perhaps you are not sure yet, either. That’s fine—begin to work on comparing scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions. Eventually you will be able to clarify for yourself, and then for the reader, why this contrast matters. After examining the evidence and considering your own insights, you write: Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave â€Å"civilized† society and go back to nature. This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.
