【正文】 names and figuring out what to do with them for the brief time each week that I stand in front of them. I do not consider the challenges of learning to live here part of a purposeful life. I consider those issues existential in nature. One of the problems with my life in America was that I felt it had no purpose. I went to work every day and even did what I could to make my colleagues39。 he wondered how in the world he came to belong there. Indeed his penning and publishing this essay caused his exmunication from high society and also caused him a lot of legal trouble. The legal trouble came as a result of the fact that he was speaking out against the government. I like to reference such texts from time to time as an example both of the fact that history does repeat itself and that this world is not so big that what applies to one society does not in any way touch another society. On a much smaller scale,Emerson39。s to e and recapping the key points. This device, not used in the original, is culturally understandable but artistically mediocre. What puzzles me is the two new songs for the opening and end credits. They were written in English, but sung by Chinese with an unfortable accent. They were obviously designed to appeal to an Englishspeaking base, but do not jibe with the Chinese dialogue. Speaking of the dialogue, the English translation, picked apart by some Chinese, is too literal for my taste. I can imagine a typical American hit by a flurry of royal ranks, addresses 成人教育學(xué)院函授 畢業(yè)論文：催化裂化產(chǎn)品質(zhì) 量的控制 18 and greetings, even multiple names and titles for the same person. The first half hour must be a swamp to wade through, very much like my experience of getting through a Tolstoy tome with its endless inflections of names transliterated into lengthy Chinese. I see the choice of verbatim translation as an effort for conveying exotica. It is fairly petent, with no error that I could detect, but fails to rise above words or capture the essence of the language. A cultural product usually crosses over to a foreign territory first by an emphasis on the monalities. But whether inside or outside China, the temptation to sell it for the differences is just too great. Sure, the sumptuous sets and costumes are a big attraction, but the narrative technique has bee－ how shall I put it?－ a bit anglicized, which is necessary for cultural export. Judging by the responses, this legend, which, contrary to the claim of the English trailer, is totally fictitious, has departed from China but not yet landed on American shores. I am a big fan of Ralph Waldo Emerson39。s president, who is also a renowned tenor, tells China Daily. During a tour in 1985, he went to a village and met an elderly local man, who told him a story about his friendship with a solider from Shenyang, capital of Northeast China39。t just about sharing art with nomadic families but also about gaining inspiration for the music and dance. Ulan Muqir literally translates as red burgeon, and today39。s Zhangye city during their journey to Kazakhstan, May 5, 2022. The caravan, consisting of more than 100 camels, three horsedrawn carriages and four support vehicles, started the trip from Jingyang county in Shaanxi on Sept 19, 2022. It will pass through Gansu province and Xinjiang Uygur autonomous region, and finally arrive in Almaty, formerly known as AlmaAta, the largest city in Kazakhstan, and Dungan in Zhambyl province. The trip will cover about 15,000 kilometers and take the caravan more than one year to plete. The caravan is expected to return to Jingyang in March 2022. Then they will e back, carrying specialty products from Kazakhstan A small art troupe founded six decades ago has grown into a household name in the Inner Mongolia autonomous region. In the 1950s, Ulan Muqir Art Troupe was created by nine young musicians, who toured remote villages on horses and performed traditional Mongolian music and dances for nomadic families. The 54yearold was born in Tongliao, in eastern Inner Mongolia and joined the troupe in says there are 74 branch troupes across Inner Mongolia and actors give around 100 shows every year to local nomadic people. I can still recall the days when I toured with the troupe in the early 39。 感謝同學(xué)們?nèi)暌詠韺ξ业年P(guān)心和幫助，跟她（他）們在一起，就像自己的兄弟姐妹一樣，親切而又充滿樂趣。 感謝我的畢業(yè)指導(dǎo)老師（王老師） 一直以來對我的幫助， 從 論文題目 的選擇到 論文的最終完成， 王 老師都始終 如一地 給予我細(xì)心的指導(dǎo)和不懈的支持。 此外， 對石油煉制工藝學(xué)的知識有了進(jìn)一步的鞏固， 除了 對茂石化的概貌和第二套催化裂化裝置的主要裝置的作用、加工原理、工藝流程、主要設(shè)備、工藝指標(biāo) 等有一個較為全面的感知與學(xué)習(xí)，還重點(diǎn)學(xué)習(xí)了 產(chǎn)品崗位中應(yīng)如何控制產(chǎn)品的相應(yīng)質(zhì)量指標(biāo)，使之符合國家所規(guī)定的質(zhì)量標(biāo)準(zhǔn)。在進(jìn)入 煉油廠區(qū) 前，我們首先要進(jìn)行三級安全教育。而 生 產(chǎn)實(shí)習(xí)的各個環(huán)節(jié)可以培養(yǎng)我們的工藝觀念，訓(xùn)練我們的實(shí)際工作能力，提高綜合素質(zhì)，為今后從事石油化工生產(chǎn)和科研工作打下良好的基礎(chǔ)。 ，改變進(jìn)料口位置。 304 壓力低，穩(wěn)定汽油的初餾點(diǎn)高，蒸汽壓低。 。原第三章 催化裂化產(chǎn)品質(zhì)量的控制 13 料油含硫高則液 化氣 H2S 含量高。 。 401 操作溫度高。 ，提高回流比，降低回流溫度； 10%點(diǎn)合格的條件下，降低換 304 出口溫度； 304 壓力，并保持平穩(wěn)； ，選擇適宜的進(jìn)料口，提高精餾效果； ，要停工處理； 302 底溫，控制好塔 304 壓力，可適當(dāng)提高操作壓力 。 b. 如果因吸收過度，可采用降低塔 301 吸收劑量、提高進(jìn)料溫度、提高兩個中段回流溫度、降低回流量等辦法。 液態(tài)烴中 C2 含量的控制 302 底溫度過低，或塔操作壓力偏高，脫吸收效果不好。 ， 不能時大時小，而且要保證從上進(jìn)口進(jìn)入的量，從而保證催化劑在脫過熱段被洗滌下來。 ，特別是壓力波動、流化不正常，固體含量增高。油漿固體含量包括兩部分：催化劑顆粒、焦粒。為此，把餾出的輕柴油送入汽提塔，靠 塔下部吹水蒸氣汽提而使輕組分汽化。但當(dāng)條件發(fā)生變化時，如壓力低，深度大，處理量大，即使保持原來的控制值，也不可能保證產(chǎn)品合格，這時控制值應(yīng)稍降低。 閃點(diǎn) ： ， 閃點(diǎn)高。 ，餾出溫度高。 控制 95%的餾出溫度 （凝固點(diǎn)）的重要意義就是保證該燃料使用要求和不同氣候條件下有良好的流動性，而控制閃點(diǎn)，則是為了保證在輸送、保管及使用過程中的安全，閃點(diǎn)愈低愈容易發(fā)生閃火，即容易發(fā)生爆炸和火災(zāi)事故。 綜上所述是：調(diào)節(jié)塔頂循環(huán)回流取熱量以調(diào)節(jié)塔頂溫度，保證汽油干點(diǎn)合格。 ，塔頂溫 度會隨之上升，要保持原溫度或壓低 1℃左右。 、分餾吹蒸汽量大，干點(diǎn)高。 ，干點(diǎn)降低。 粗汽油質(zhì)量控制的意義 在于保證用戶在使用過程中具有良好的汽化性能和完全燃燒性能，以達(dá)到充分有效的作功 ，粗汽油干點(diǎn)的偏高或偏低都會間接影響汽油的辛 烷值，所以要控制好粗汽油的干點(diǎn)。 溶劑單獨(dú)再生時： 從塔 40塔 402 底出來的富液先進(jìn)入閃蒸罐（容 409），在低壓下閃蒸出來的烴類從罐頂進(jìn)入火炬管線，容 409 富液用泵 403/ 加壓后與再生塔底熱貧液換熱 (換402/)，升溫到 87℃ 左右進(jìn)入再生塔（塔 403）第 12 層塔盤，塔內(nèi)設(shè)有重沸器（換 402），用 或 （表）蒸汽加熱，維持塔底溫度約 120℃ ，塔頂壓力 ，成人教育學(xué)院函授 畢業(yè)論文：催化裂化產(chǎn)品質(zhì)量的控制 8 被蒸脫出的 H2S、 CO2 及一部分水蒸氣
