Swiss speciality chemicals company Clariant has announced the start-up of its CATOFIN catalyst at Hengli Group’s new mixed-feed dehydrogenation plant in Dalian, China.Clariant said that the new unit combines propane dehydrogenation (PDH) with iso-butane dehydrogenation (BDH) process technologies, and produces more than 1 million tons of olefins per year.Chinese dehydrogenation plant becomes the largest plant to use CATOFIN catalyst technologyThe advanced process combines Clariant’s CATOFIN catalyst together with McDermott’s Lummus process technology and is set to enable enhanced reliability, yield, cost efficiency and simplicity.Clariant said that in addition to the CATOFIN catalyst, the facility also employs its innovative Heat Generating Material (HGM) to produce its on-purpose olefins.Hengli Group’s new dehydrogenation plant in Dalian is designed to process 500KTA of propane and 800KTA of iso-butane feeds to produce propylene and iso-butylene.Hengli Petrochemical Refinery chief engineer Guangqin Peng said: “We are very proud of our achievements on this groundbreaking project. The fast, smooth and successful startup of this world’s largest paraffin dehydrogenation unit would not have been possible without reliable and experienced partners like Clariant.”Clariant said that its CATOFIN catalyst is an extremely reliable technology customised for the production of light paraffin dehydrogenation, and on-purpose production of propylene.CATOFIN technology and catalysts facilitates dehydrogenation of isobutane, n-butane or propane to isobutylene, n-butenes or propylene respectively, based on the Houdry process of catalytic cracking.The process at the new facility depends on a highly selective CATOFIN catalyst and operates at a thermodynamically-advantaged reactor pressure and temperature to maximize yield.The startup of the Hengli plant marks the 21st CATOFIN unit in operation, making Clariant’s total olefin production capacity more than 9million tons.Clariant Catalysts business unit senior vice president & general manager Stefan Heuser said: “We are honored that our CATOFIN catalysts and Heat Generating Material were selected by Hengli for its new production facility. Together with our technology partner, McDermott’s Lummus Technology, we are proving, yet again, the outstanding benefits of CATOFIN for propane and iso-butane dehydrogenation.”last_img read more

By-by election after LMH online vote ‘lacks secrecy’

first_imgA complaints tribunal has called for the results of Lady Margaret Hall’s JCR by-election to be annulled after the reliability of the online voting system used was called into question.According to the tribunal’s report, several undergraduates complained to the Returning Officer during last Thursday’s election that there were “insufficient protections against electoral fraud” and that the ballot “lacked due secrecy”. Other students reported that their anti-virus software prevented them from accessing the voting page.There was also confusion on election day after it emerged that the online system allowed voters to mark the same candidate as their first and second choice. Many thought that doing this would increase the sway of their vote, when in fact it spoilt their ballot.Ashley Thompson, the JCR’s IT representative, sent an email to students just after midday on polling day to advise voters against placing the same candidate as their first and second choice.However in the same email, he wrote, “You can’t put down a first choice for VP and then leave the remaining options blank.”The preferential voting system used by LMH does not require all choices to be used, and Thompson was forced to issue a further correction later in the day.Some students expressed concern that the system did not adequately protect the privacy of individual votes after discovering that individually identifiable results were amalgamated in one spreadsheet.Thompson claims that he protected the confidentiality of individual votes. He explained, “I had the votes in a spreadsheet with e-mail addresses, voting pins and actual votes in separate columns. While I was validating e-mail addresses I had the voting columns hidden, and before I started counting votes I deleted the e-mail address/voting pin columns.”However Returning Officer Nathalie Higgs decided not to release the results of the by-election when polling closed, and forwarded the complaints she received to a tribunal formed of three former JCR officers. The complaints tribunal released its report on Wednesday, in which ex-JCR President David Tan criticises the current JCR Executive for not ensuring an effective system was in place.“The planning for this online election smacks of being naive at best, and inept at worst,” he wrote.It is the first time that LMH has held an election online. Tan suggests that the JCR Executive’s decision not to use a more traditional method was based on “saving themselves from having to sit for an hour at the ballot box.”“It is surprising that at no point did the JCR Exec think to consult the JCR as a whole as to their views concerning online voting,” he continued.Asked if he felt anyone should resign following the incident, Tan said, “You may very well think that. I couldn’t possibly comment.”JCR President Marlene Cayoun said that the vote was held online to make it more accessible.“We wanted to make it easier for people who live out, who sometimes find it hard to come into college to vote,” she said. “It’s a shame that it didn’t work out, but our motives was [sic] sound.”Higgs agreed that the move was based on good intentions. “We wanted to try and increase the turnout of voters. In the previous elections only 160 people voted out of an electorate of 400.”The College’s JCR will meet on Sunday night to decide whether to accept the tribunal’s recommendation that a “by-by-election” be held. The debacle means that the JCR is still without a Vice-President or OUSU Officer.Both positions were left vacant when the winners of the College’s Michaelmas elections resigned before taking up their roles.Alasdair Craig, who won the election for VP in Michaelmas, was forced to resign when College authorities objected to election posters that depicted him holding a carrot in his trouser flies.Georgina Day resigned as the College’s OUSU representative earlier this term, saying her position had become “awkward.”Charlotte Dyke, one of the candidates for Vice-President in the by-election, said, “Problems that arose could not have been foreseen before the election took place. It was evident that a lot of research had gone into the online system in order for it to work.”last_img read more

Outrage over naked KY jelly wrestling at Kukui

first_imgA student club night featuring naked wrestling in KY jelly, topless girls and a ‘fetish snake show’ has sparked an investigation by police this week.The probe into a potential breach of licence was launched after revellers visiting the Kukui nightclub on Wednesday October 29 were astonished to find that a virtual sex show had been laid on as entertainment.The event, organised just days before the start of Oxford University Student Union’s Gender Equality Week, had been billed as “one of the naughtiest nights of the year,” and has been condemned by students who attended.One undergraduate described how she entered the venue and found herself surrounded by raunchy performers.“There were girls covered in jelly and wrestling with each other,” she said.“They were only wearing small t-shirts, which they then ripped off and continued as good as naked except for tiny thongs.”She added that there had also been a topless woman only partially covered by a 12 foot long snake she was carrying, whilst others put on performances of topless fire-eating.Another shocked student said that she and her friends had been left disgusted by the naked displays.“There was a group around the girls that seemed to think it was great, but my friends and I were really embarrassed.“The whole thing just descended into something that was really vile and made a lot of people feel a bit uncomfortable.”Adverts for the event on Facebook had told partygoers to adopt a “scary” dress code and prepare for “f**ked up Halloween sh*t,” with promises of “KY Jelly Wrestling ‘Naked’” and “Fetish snake shows involving a 12 foot albino python.” Rachel Cummings, OUSU Vice-President for Women launched a scathing attack on the night and condemned it as hugely inappropriate.“It’s unacceptable for club organizers to use women in this way,” she said.“Such acts demean women in a city where they have fought for their rights to be taken seriously as intelligent, autonomous individuals.“Its accounts like this that prove the need for continuing campaigns on gender equality.”The spokesperson for Five Star Entz, the Oxford based company which organised the night, declined to comment when asked about this issue.He did however defend the entertainment as “a kind of Halloween fetish show.”“It wasn’t all centred around the KY Jelly wrestling, although obviously this is something that we gave a lot of publicity to as it is a big student thing,” he explained.There have however been efforts to run follow-up wrestling events since the initial night, which was mainly attended by students from Oxford Brookes.A similar ‘KY Jelly Wrestling Election Special’ night, run in conjunction with club promoter Balreick Srai, was cancelled on Tuesday at the last minute.The Rock Entz head said, “We cancelled the wrestling because we didn’t want the negative publicity.“This is a new club and we don’t want this to be the first thing written it. It’s not the image we want to present.”As accounts of the event filtered through there were additional concerns that organisers may have potentially violated licensing laws regarding in-club entertainment.A spokesperson for the Licensing Authority of Oxford City Council confirmed that an investigation into the legality of the performances had been conducted in conjunction with officers from Thames Valley Police.He said however that officials were now satisfied that no crime had been committed.“As the law stands at the moment there is nothing to stop them extending their current license for dancing and putting on pole-dancers and the like.last_img read more

Colleges under pressure after flooding damage

first_imgOxford suffered from flash flooding last week due to torrential rainfall, causing substantial disruption to students and commuters.According to the Met Office, Oxfordshire suffered the heaviest rainfall in the UK last Thursday night, as thunderstorms hit the county for five hours from 17:00.A number of colleges were affected by the flooding, including Magdalen, Mansfield, Pembroke, and Wadham.Heavy rain caused the guttering at Wadham to overflow, which left the top of the library, the MCR, and five student bedrooms affected.A spokesperson for Wadham told Cherwell: “Alternative arrangements were put in place for student bedrooms and the top floor of the library was reopened the day after the incident.”Meanwhile, Mansfield students helped to mop water out of the café area, which had leaked through from the flooded road outside. The rain also came through the roof of Somerville’s college bar, and flooded their patio area. However, the flooding was gone the followingday.Elsewhere in Oxford, around 100 people had to be evacuated from an Oxford Pride show taking place at the Old Fire Station, after water started leaking through the roof. Botley Road, a main route into Oxford from the west of the city, had to be closed due to several feet of water pooled under a railway bridge. Firefighters attended the affected area and the road was reopened by the next morning.Commuters experienced delayed trains from Oxford, due to flooding on the line and at nearby station Didcot Parkway.last_img read more

VIDEO: Gergen speaks at HLS on the 2012 presidential race

first_imgRarely has a presidential race been so hard to call, said David Gergen ’67, during a talk on Oct. 26 at Harvard Law School Fall Reunions. A former adviser to four presidents, a regular contributor to CNN, and a professor at the Harvard Kennedy School, Gergen put the race between fellow HLS graduates Mitt Romney ’75 and President Barack Obama ’91 in historical perspective, analyzed its development, talked about its import—and made some predictions.Gergen broke the campaign into three stages: The first started “before all the fisticuffs,” when observations on the state of the economy, including studies using economic and political forecasting models which have successfully predicted many past elections, indicated that Obama was going to lose, and in fact be a “45 percent candidate.”The second stage started, he said, in October 2011 as the campaign got under way, “President Obama forged into the lead and defied expectations and remained steadily in the lead against all comers, including Mitt Romney, for an entire year.” Why was that, Gergen asked? “Simply put, it was that the Obama campaign was a better run campaign.“That was stage 2. It all ended on October 3 at 9:00 at night.” That first presidential debate changed everything, said Gergen, “and turned this into a real horserace. I don’t know what happened with either side.”Read more about Gergen’s take on the Presidential race on the Harvard Law School website.last_img read more

Low-fat diet not most effective in long-term weight loss

first_img Read Full Story The effectiveness of low-fat diet on weight-loss has been debated for decades, and hundreds of randomized clinical trials aimed at evaluating this issue have been conducted with mixed results. Researchers from Brigham and Women’s Hospital (BWH) and the Harvard T.H. Chan School of Public Health (HSPH) conducted a comprehensive review of the data generated from randomized clinical trials that explored the efficacy of a low-fat diet and found that low-fat interventions were no more successful than higher-fat interventions in achieving and maintaining weight loss for periods longer than one year.These results were published in The Lancet Diabetes & Endocrinology on October 30, 2015.“Despite the pervasive dogma that one needs to cut fat from their diet in order to lose weight, the existing scientific evidence does not support low-fat diets over other dietary interventions for long-term weight loss,” said Deirdre Tobias, a researcher in the Division of Preventive Medicine at BWH. “In fact, we did not find evidence that is particularly supportive of any specific proportion of calories from fat for meaningful long-term weight loss. We need to look beyond the ratios of calories from fat, carbs, and protein to a discussion of healthy eating patterns, whole foods, and portion sizes. Finding new ways to improve diet adherence for the long-term and preventing weight gain in the first place are important strategies for maintaining a healthy weight.”last_img read more

Saint Mary’s President spends night in dorm, bonds with residents

first_imgIn an effort to better understand the student experience, Saint Mary’s President Jan Cervelli gave dorm life the old college try, spending the night in a quad in Le Mans Hall on Thursday.“Since I began as President, I’ve wanted to experience daily life in a Saint Mary’s dorm from a firsthand perspective,” Cervelli said. “I received an invitation from juniors Abbie Spica, Sam Allen and Katie Long to join them for a slumber party. It was a great opportunity to see how our students live, learn and socialize in our residence halls and to personally experience if our dorms are meeting students’ needs and keeping them engaged.”Cervelli said her night included a section event with the residents of the second annex in Le Mans, during which she was able to meet and talk with residents in the hall while celebrating one student’s birthday. Cervelli said she also brought her guitar and performed a number of Joni Mitchell songs. Tags: cervelli, Le Mans Hall, residence halls, sleepover Photo courtesy of Kara Kelly Students pose with Saint Mary’s President Jan Cervelli in Le Mans Hall on Thursday night. Cervelli spent the night in a dorm room with three students to gain a better understanding of what residential life is like for students at the College.Spica, who lives in the room Cervelli slept in, said she enjoyed the experience.“It was so cool to see a social and human side of an administrator,” Spica said. “She genuinely showed that she wanted to connect with us and that she likes spending time with students.”Cervelli said her favorite part of the slumber party was interacting with students.“I really enjoyed the gathering of second annex residents, stopping by and checking out various rooms and chatting with students about a wide range of subjects,” she said. “Abbie, Sam and Katie were warm and welcoming and made sure my every need was met, including giving me the most comfortable bed in their room. I learned about their studies, their hopes and dreams for the future and how dedicated they are to helping make the world a better place. I feel a special bond with these wonderful women.”Cervelli said participating in the sleepover will help her better lead the College.“I better understand the quality and depth of our students’ connection with one another,” she said. “I saw that the physical structure and layout of the historic building does a good job of accommodating students’ needs but that we need to make continuous improvements to Le Mans and other residence halls to keep the quality high. I learned that students really like living on campus and are mostly satisfied with their living environment and that the camaraderie between residents living on campus far outweighs occasional slow WiFi.”The sleepover mostly consisted of talking about student life at Saint Mary’s, according to Spica.“I learned that President Cervelli is not only devoted to helping Saint Mary’s grow as a community, but I also learned that she cares about students on an individual basis,” Spica said. “She wants to know about personal lives of students, and I think that is unique because it makes us feel valued.”Cervelli said she has received other invitations for sleepovers and hopes to make it an annual event.last_img read more
