Ⅰ 用什么方法能代替实沸点蒸馏
恩氏蒸馏只能做常压那段馏程，到了一定温度，如果继续常压蒸馏的话，页岩油就反应了，因为它含有大量的不饱和烃。
Ⅱ 为什么通过实沸点蒸馏实验并不能得到其中单体化合物的真实沸点
实沸点源蒸馏------气压自蒸馏
减压蒸馏------低压环境蒸馏
模拟蒸馏------种软件析
恩氏蒸馏------Engler distillation
种用测定石油产品馏组经验性标准种简单蒸馏馏程度低能用于石油油品馏程相比较或油品轻重馏相含量作致判断炼油工业用作油品质量重要指标
没有意义
建议自己下去查查资料
Ⅲ 请朋友帮忙把这段话翻译成英文 谢谢
China's crude oil proction in recent years has been hovering around 18.5 thousand tons, nearly 10 years, crude oil proction growth has also been no more than 4%, a typical example is the Daqing Oilfield, the country's oil output is currently occupied 1 / 3 of the Daqing oil field began in 2004 7 year plan to rece average annual crude oil output by about 7% in 2010 fell to 30 million-ton level. Oil instry, how to adapt to the future, this new proction situation, to participate in market competition has become a very serious problem, rece processing costs, improve economic efficiency, improve proct quality and development of high value-added fine chemical procts has become the face of China Petrochemical Instry critical work. Tower equipment is also an important petroleum chemical instry equipment, so tower equipment design and quality is essential. How to expansion efficiency, saving energy. Such as improving the tower structure and improve tower efficiency and operating flexibility. These are the towers facing designers of new research and development of new hot spots.

Ⅳ 异丙酯馏程是多少
在标准抄条件下，蒸馏石油所得的沸点范围称为“馏程”。即是在一定温度范围内该石油产品中可能蒸馏出来的油品数量和温度的标示。
馏程是指以油品在规定条件下蒸馏所得到，从初馏点到终馏点表示蒸发特征的温度范围。馏程是石油产品的主要理化指标之一，主要用来判定油品轻、重馏分组成的多少，控制产品质量和使用性能等。
采用恩氏蒸馏方法，即取100毫升试油在规定的仪器上，按规定的条件和操作方法进行。这种蒸馏是条件性的，蒸馏出的数量只是相对的比较数量，而不是真正的数值，即不是实沸点的蒸馏。但这仍然是控制汽油、煤油、喷气燃料和柴油等轻质燃料和各种溶剂油的重要指标。异丙酯可以参考其方法。
例如醋酸异丙脂馏程馏程为（℃,760mmHg） 87.0~92.0 195.0~200.0
Ⅳ 原油实沸点蒸馏实验常压蒸馏为什么将温度降低至100摄氏度以下
减压蒸馏
也称真空蒸馏。原油中重馏分沸点约370～535°C,在常压下要蒸馏出这些馏分,需要加热到420°C以上,而在此温度下,重馏分会发生一定程度的裂化。因此,通常在常压蒸馏后再进行减压蒸馏。在约2～8kPa的绝对压力下，使在不发生明显裂化反应的温度下蒸馏出重组分。常压渣油经减压加热炉加热到约380～400°C送入减压蒸馏塔。减压蒸馏可分为润滑油型（图3）和燃料油型两类。前者各馏分的分离精确度要求较高，塔板数24～26；后者要求不高，塔板数15～17。 通常用水蒸气喷射泵（或者用机械抽真空泵）抽出不凝气，以产生真空条件。近年来发展的干式全填料减压塔（见填充塔）采用金属高效填料代替塔板，可以使全塔压力降减少到 1.3～2.0kPa，从而可以提高蒸发率，并减少或取消塔底水蒸气用量。 全自动原油蒸馏仪
为了在同一炉出口温度下使常压渣油有最大的汽化率，减压蒸馏都将炉出口至塔的管线设计成大管径的形式（见彩图），以减少压降，进而降低炉出口压强。减压塔顶分出的馏分减（压、拔）顶油，一般作为柴油混入常压三线中，减压一线至四线作为裂化原料或润滑油原料，塔底为减压渣油，可作为生产残渣润滑油（见溶剂脱沥青）和石油沥青的原料，或作为石油焦化的原料，或用作燃料油。

一种常属用的测定石油产品馏分组成的经验性标准方法。是一种简单蒸馏，分馏程度很低，只能用于石油油品馏程的相对比较或油品中轻重馏分相对含量作大致判断。但在炼油工业中常用作油品质量的重要指标。

摘 要 Abstract：
常减压塔蒸馏装置作为原油的一次加工工艺，在原油加工的总流程中占有重要作用，在炼厂具有举足轻重的地位。它的操作平稳是保证石油产品质量的关键。本次设计主要是设计原油年处理能力为 万吨的常压塔，其次为塔板的设计。
As a part of the crude oil processing technology, the atmospheric-vacuum distillation unit plays an important function in the overall technological procere of crude oil processing. Its smooth operation is critical to the quality assurance of petroleum procts. The primary objective of this design is for the atmospheric- vacuum tower with an annual crude oil processing capacity of xx tons; the second design is for the tower trays.
设计的基本方案是：初馏塔拔出石脑油，常压塔采取三侧线，常压塔塔顶生产汽油，三侧线分别生产煤油，轻柴油，重柴油。塔底重油作催化裂化或加氢裂化装置的原料。常压塔的设计主要是依据所给的原油实沸点蒸馏数据及产品的恩氏蒸馏数据，计算产品的各物性数据确定切割方案、计算产品收率。
The basic design is: primary tower extracts the naphtha, the atmospheric-vacuum tower adopts three lateral lines; petroleum is proced at the top of the tower, the three lateral lines separately proce kerosene, light diesel and heavy diesel. The heavy oil at the bottom of the tower will be used as raw material for catalytic cracking unit or hydrocracking unit. The design of the atmospheric-vacuum tower is to calculate the various physical data of procts to determine the cutting plan, as well as calculate the proct yield basing mainly on the provided true boiling point distillation data of crude oil and the Engler distillation data of procts.
参考同类装置确定塔板数、进料及侧线抽出位置，在假设各主要部位的操作温度及操作压力，进行全塔热平衡计算，采取塔顶二级冷凝冷却和两个中段回流。塔顶取热：第一中段回流取热：第二中段回流取热为5：2：3，最后校核各主要部位温度都在允许的误差范围内。
塔板形式选用浮阀塔板，依据常压塔内最大汽、液相负荷处算得塔径为4.2m，板间距取0.8m。这部分最主要的是核算塔板流体力学性能及操作性能，使塔板在适宜的操作范围内操作。
Refer to similar unit to decide on the number of tower trays, feed inlet and lateral line extraction positions. Conct the heat balance calculation of the tower with the hypothesis of the operating temperature and pressure of the various key positions; adopt tower top two-stage condensing and cooling and two middle-stage reflux. The arrangement of taking temperatures at the tower top, first middle-stage reflux and second middle-stage reflux is 5:3:2. Finally check the temperatures at various key positions are within the permissible deviations.
The type of tray used is the float valve trays; based on the maximum gas-liquid load in the tower, the tower diameter is 4.2 meters, the distance between the trays is 0.8 meter. The most important in this section is to calculate the hydrodynamic and operating performance of the tower trays, so that the tower trays are operating within the suitable operation scope.
