  1. 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

    數值析的結果表明塔靈敏板位置並不在進料板附近,而是位於段的中上部,且迴流比愈小,愈靠近塔頂;利用matlab實現了蒸過程的嚴格計算,與參考值比較,結果正、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佈,經過理論析,結果合理,可為實際生產提供參考。
  2. Some of problems in distillation technology process are studied using excel, matlab and chemcad. they are distillation with simple balance, determining accurately the position of sensitive plates in distillation tower, distillation of multi - components, and crude distillation at steady state. this paper shows how to solve bubble & dew points for binary ideal system and five cases of flash by means of excel and analizes reducing pressure affects on phase equilibrium as an example of distillation and separation ethyl benzene & phenyl ethylene below atmosphere

    基於excel 、 matlab和chemcad軟體,對蒸過程中的簡單平衡蒸塔靈敏板位置定方法、多組等進行了數值計算與定量研究,對原油煉制常減壓塔進行了初步的穩態模擬,實現了用excel求解雙組理想體系的泡、露點問題和閃蒸計算的五種情況,並析了減壓對其相平衡的影響。
