  1. Determining of the smallest reflux ratio of distillation operation

    談精餾操作最小迴流比的確定
  2. The results indicate that the position of sensitive plates is located at the section of middle or upper in tower but not near by feeding plate, and the smaller reflux ratio, the closer overhead of distillation tower. accurate calculation for flash is solved using matlab, and the result is correct and reasonable. complicated multi - components distillation and crude distillation are simulated using chemcad, and results are reasonable about profiles of flow for vapor and liquid as well as temperature in the tower

    數值分析的結果表明精餾塔靈敏板位置並不在進料板附近,而是位於精餾段的中上部,且迴流比愈小,愈靠近塔頂;利用matlab實現了蒸餾過程的嚴格計算,與參考值比較,結果正確、合理;藉助于chemcad進行常減壓塔的穩態模擬計算,得出了流量和溫度在塔內的分佈,經過理論分析,結果合理,可為實際生產提供參考。
  3. Limiting concentration of light component in distillate of binary batch distillation under constant reflux ratio

    恆迴流比二元間歇精餾輕組分的極限濃度

  6. The influence of packing height, ratio of water to entrainer and acetic acid initial concentration to separation effect of azeotropic distillation was studied in detail. simulation calculations of general distillation and azeotropic distillation were carried out. the influence of reflux ratio, theoretical plate, feed position, feed temperature and feed concentration to distillation process were discussed

    ( 3 )與普通精餾比較,分離要求相同時,共沸精餾時所需要的理論板數要低於普通精餾所需要的理論板數,迴流比減小,可降低設備投資70萬元,塔釜加熱量減少36 % 。
  7. 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。
