  1. The recovery of atmospheric light oil yield of atmospheric in the northern atmospheric distillation tower of shenghua teaching & test factory, science and technology group of china university of petroleum has been increase by about 4 or 5 percent through the following methods : changing the tray perforation of atmospheric tower, adjusting the amount of stripping steam and the outlet temperature of the atmospheric heater and merging atmospheric excess vapor into 3rd atmospheric drawn - stream to keep the fractions content of bottom oil below 5 % before 350

    摘要中國石油大學科技集團勝華教學實驗廠北常減壓蒸餾裝置換煉勝利管輸油后，通過改變常壓塔塔盤開孔率、調節常壓塔汽提蒸汽量和常壓爐出口溫度、常壓過汽化油併入常三抽出線等措施，控制常壓塔底油350前餾分含量小於5 % ，使常壓輕質油收率提高約4 % ~ 5 % 。
  2. Secondly, for the first time, by volume average concept and reynolds time - average method, a 3d quasi - single phase mass transfer model of distillation tray is deduced by considering the effects of velocity fluctuation, concentration fluctuation and volume fraction of gas and liquid on mass transfer. a source item sc for interphase mass transfer is considered. by applying conventional method of estimating the interphase mass transfer coefficient, a formula for sc is obtained

    其次，採用體平均概念、雷諾時均化方法結合塔板氣液相互作用的實際情況首次推導了考慮速度、濃度脈動項和氣、液相含率影響的塔板三維擬單相流湍流傳質模型，源相中考慮了氣液相間傳質項sc ，並運用化工中關于相間傳質系數計算的理論，推導了sc的表達式。
  3. For example, in order to solve these variables measure such as distillation tower production component 、 tray efficient 、 reactant concentration 、 conversion and so on in petrochemical produce

    為解決這類變量的測量問題，軟測量技術得到了很大的發展。
  4. The finite volume method and the star - cd software are used to compute the fluid flow process and mass transfer process of one tray and for the first time of the whole distillation column ( 10 trays ) under the total reflux. the computed results are as follows : 1. since the previous research did not show the comparison between the computational results and the measured values of 3d fluid field on a distillation tray, attention is paid to present work in this paper

    本文採用有限體積法及計算流體力學軟體「 star - cd 」對單塊板以及首次對全迴流下的全塔（十塊板）流體流動、傳質過程進行了計算，計算結果如下： 1 .泡沫工況下單塊板的流場計算值與solari及bell （ 77 （的實測值吻合較好。
