Distillation Essay -- essays papers

Distillation Abstract This report outlines the steps taken to separate a 50:50 by volume ethanol and isopropanol side stream. The resulting separation must contain no more than 3% alcohol impurity in each product. A laboratory column, run at total reflux, was utilized to scale up to a forty foot high by one foot diameter column. The laboratory column allowed the team to determine vapor velocities and HETP values for the 0.24 inch Pro-Pakq packing. HETP is defined as the height of packing divided by the number of theoretical column stages. The column consisted of four main sections: packing, controls, a reboiler, and a condenser. To complete the vapor velocity vs. HETP relationship, the vapor velocity must be found. The vapor velocity was found using a system energy balance. The design vapor velocity was determined to be 4.85 ft/hr. However, this vapor velocity did not result in the column flooding; therefore the scaled-up column is not designed to its full potential. Ideally, distillation columns should be designed at 70-80% of the flooding velocity. The column HETP was found by use of the Fenske equation and was determined to be an average of 4.55 inches. As a result of the design parameters from the experimental column, the following design is proposed: the column will run at a vapor velocity of 4.85 ft/hr and will have a HETP of 4.30 inches. This will result in a packing height of 38.7 feet. The reboiler will have an area of 113.52 ft2 and the area of the condenser will have a value of 45.54 ft2 in which heat exchange will take place. Introduction A chemical plant spends approximately 50 to 90% of capital investment on separation equipment (1,1) Therefore, the ability to utilize a small laboratory column and to scale-up a column is an important skill for a chemical engineer. This report will outline the steps taken to design a packed distillation column. The column needs to separate a 50:50 mixture of ethanol and isopropanol into a distillate stream containing no more than 3 wt% isopropanol and a bottoms stream containing no more than 3 wt% ethanol. The design of the full-scale column was based on a laboratory simulation column. This column allowed the team to determine vapor velocities and HETP values for the 0.24 inch Pro-Pakq packing. Once the simulation vapor velocities are determined, they can ... .../hr)/*(1/0.0154 kmol/L)*(1/(p(.25)2ft2)*(0.0159 kmol/L) (p(1)2(ft)) = 6.857567 kmol/hr MWAVG,D = 46.493 kg/kmol VD = (6.857567 kmol/hr) * (46.493 kg/kmol) VD = 318.82886 kg/hr *Equation of Top Operating Line y = (L/V)x + (1-(L/V))xD = (RACT / RACT +1)x + (1/ RACT +1)(0.97) = 0.912779x + 0.084605 *Distillate Rate R = (V-D)/D = 10.4651 318.82886 (kg/hr) - D = 10.4651D D = 27.808642 (kg/hr) R = L/D = 10.4651 * 27.808642 (kg/hr) = L L = 291.02022 (kg/hr) *Bottoms Flow Rate L/V = R (z -xB) + q (xD - xB) R(z -xB) + q(xD-xB) -(xD-z) z= Feed mole fraction of ethanol q= 1 (feed assumes to be liquid) L/V = 10.4651(0.567-0.03) + 1(0.97-0.03) 10.4651(0.567-0.03) + 1(0.97-0.03) -(0.97-0.567) L/V = 1.05 L/V = (VB + 1)/ VB = 1.05 VB = 20 B = V/ VB = (318.82886 kg/hr)/20 = 15.941443 (kg/hr) *Feed Flow Rate F = D + B = 15.941443 (kg/hr) + 318.82886 (kg/hr) = 334.7703 kg/hr *Bottom Operating Line y = (L/V)x - ((L/V)-1) xB = 1.05x - 0.0015 * Condenser Heat Duty QCOND = V * DHVAP DHVAP = xETOH * DHVAP,ETOH + xISOP * DHVAP,ISOP QCOND =

American Horror Story: the Affects of Sex and Violence in Media

Media Analysis: American Horror Story American Horror Story is an FX horror-drama television show, as well as an anthology series; each season of the show has a different cast and storyline. The show was created by Ryan Murphy (creator of the FOX show Glee) and Brad Falchuk (producer of Nip/Tuck), and premiered on October 5, 2011. The first season of the show follows the Harmon family as they settle into their new home in Los Angeles. They are unaware, however, that the mansion is haunted by its many former owners. The two main topics in which we covered in class that are utilized in the show are frightening and sexual content in media.The focus of the first season is on infidelity and temptation. Ben and Vivien Harmon moved to Los Angeles from Boston with their daughter Violet in an attempt to start over and save their fragile marriage, after Ben had an affair with one of his students. Although they think the move will help, it only worsens their situation. The cable series is full of as much violence and sexual content as the writers and producers can get away with. With multiple instances of violence, sex, and nudity in every episode, the show draws a very large audience.American Horror Story is FX’s most viewed series, with the pilot of the first season bringing in 3. 2 million viewers. The show gained viewers as it progressed, and the premiere of the second season had 3. 85 million viewers. In an interview by AfterElton. com contributor Brian Juergens, when asked about what he wanted to bring to the horror genre, producer Brad Falchuk said â€Å"In the case of the horror genre, your main goal is to scare people. You want people to be a little bit off balance afterwards. You want people to have their friends sleep over that night.And you want to deliver iconic images that stay with people. † The writers of American Horror Story make use of many of the subjects from chapter 13 of our textbook. There are many realistic scenarios that occur in th e series, such as a home invasion and multiple murders. This is an example of stimulus generalization. Because many of the scenes are highly realistic, the generalization stimulus is very high, which consequently increases the fearful or emotional response. American Horror Story is rated TV-MA, which means that it is intended for mature audiences, and not children (usually age 17 or older).It also has a sub rating of LSV (offensive language, strong sexual content, and violence and gore). R-rated videos and magazines contain far more profane and explicit sexual content than network television shows, but sexual remarks and suggestions are becoming ever more frequent in public media today. In American Horror Story there are elements of the four major themes of sexuality in media. Sexual scenes in the show include examples of domination (sexual control of a person), exploitation (coercion of one person by way of power or status), reciprocity (consensual sex), and autoeroticism (self-sti mulation, such as masturbation).In the pilot of the first season Ben walks in on the housekeeper, Moira, masturbating. She tries to get him to sleep with her but he goes to another room and masturbates as well. Yet another storyline consists of Ben’s former student, Hayden, in which he had an affair with, who shows up and tries to convince him to stay with her. These scenes, along with many others throughout the season, go back to the theme of infidelity and temptation. The trailer for the first season of American Horror Story gives the basic plot of the show. It also makes use of frightening music and sounds to get the attention of fans of the horror genre.The season two trailer also highlights each character’s traits and occupations briefly (Leo’s photography, Shelley’s sensuality, Lana Winters’ love for her partner, Wendy, etc. ). These short advertisements appeal to viewers by the use of catharsis. The audience of American Horror Story wants to be scared. It’s a way for them to escape, or animate, their own violent predispositions or inclinations; to purge themselves of their personal worries and apprehensions. Personally speaking, I find the sadistic and erotic nature of the show enjoyable.It allows me and other viewers to gain vicious pleasure by identifying with the immoral and shady personalities of the characters in the show. The intent of the show can be pretty well summed up by the theories of scholar and professor, Dolf Zillmann, in Fundamentals of Media Effects (Bryant and Thompson): â€Å"Zillmann (1991a, 1991b) described horror as frightening because it releases empathetic responses toward victims and makes viewers apprehensive about becoming victims themselves. In other words, viewers identify with the victims and experience their terror vicariously.Horror also frightens viewers because of their apprehensions; they fear being victims themselves. Finally, horror usually features a satisfying ending that viewers enjoy. † American Horror Story has had its share of controversy with viewers already. Erin Brown, contributor for the Culture and Media Institute at the Media Research Center, writes: â€Å"The premiere of â€Å"American Horror Story† wasn't just sexually and physically repulsive. Flashback scenes also featured a large dose of verbal and mental cruelty toward a Down syndrome girl – including her mother, played by Jessica Lange, wishing she'd aborted her.To add to the violence, sex and abuse, there were 13 versions of the word â€Å"s**t,† and such delightful terms as â€Å"p***y† and â€Å"c**ksucker. † With all this objectionable content, Entertainment Weekly still named American Horror Story one of its â€Å"Top Ten Things We Love this Week† putting it on their famous â€Å"Must List† in the October 7 issue. â€Å"This show has a potential to literally be shattering to all of the things that we consider to be normal ,† one of the actors said during production. † Many parental reviews of the show describe it as disturbing, terrifying, and even repulsive.The three main age groups discussed in the Reactions to Disturbing or Frightening Media Content chapter of Fundamentals of Media Effects, 3-8, 9-12, and 12-17, are all thought to be too young for most parents. Some critics also consider American Horror Story to be a strained and overexcited mess. Though there are many frightening elements to the show, most of them are written off as cliche. The fact that in society today we are so used to seeing violence and sexual content in media, these happenings in the show are not as disconcerting as they would have been in the decades prior to the twenty-first century.

The War Prayer By Wilfred Owen - 1933 Words

Knowledge is constantly being redefined within society. Some would argue knowledge comes from logic and proven ideas, yet others would refute that knowledge develops through personal experiences and is driven by human emotions. As argued in Twain’s â€Å"The War Prayer†, knowledge is constructed by those in power, forming a narrative that is accepted by society as the truth. Through the conventions of language, authority figures are able to create a false sense of reality, a reality that is believed to be true but cannot actually be proven, as argued by Wilfred Owen in â€Å"Dulce Et Decorum Est†. While Twain’s â€Å"The War Prayer† initially follows the narrative that wartime is a hopeful and patriotic experience, the second half, as well as Owen’s†¦show more content†¦The phrases â€Å"the country† and â€Å"in every breast† creates the sense that absolutely every American believes in these familiar concepts and to fe el anything differently from the predetermined emotions picked out by the nation s leaders should cause embarrassment and self-questioning among one. The personification of patriotism as a â€Å"holy fire [that] burned,† signifies that the embers are still building, as patriotism is still rising and the nation is getting stronger with the addition of every supporter. However this â€Å"burning fire† is contrasted in the â€Å"smothering dreams [that one] too could pace†¦ his hanging face, like a devil’s sick of sin†(Owen). These patriotic dreams are â€Å"smothered,† slowly fading and soon to be put out after society is exposed to what is truthfully going on amongst the soldiers on the battlefront. The faces that display excitement from the U.S. civilians at home contrast the â€Å"hanging faces, like a devil’s sick of sin.† The faces and attitudes of these soldiers are so lifeless and gruesome that they represent that of a †Å"devil,† an image feared by a group derived from a strong religious foundation and who pray against â€Å"sin† upon such men. Though the men are previously characterized as hopeful and strong, Wilfred Owen and his personal battlefront experiences contrast this view, conveying the soldiers asShow MoreRelatedThe War Prayer By Wilfred Owen1865 Words   |  8 Pagesexperiences and human emotions develop knowledge.
