  1. Next, the air enters a high pressure distillation column where it is physically separated into a vaporous form of nitrogen at the top of the column and a liquid form of “ crude ” oxygen ( ~ 90 % o2 ) at the bottom

    隨后空氣進入高壓分裂蒸餾塔，分離成氮蒸氣和「原始」液氧（含大約90 %的氧） ，氮蒸氣在蒸餾塔頂部，液氧在蒸餾塔底部。
  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. A numeric method for computing limiting concentration of light component in the distillate of binary batch distillation under constant reflux ratio and hold - up in the column is introduced

    摘要介紹了採用恆迴流比操作方法，在塔頂、塔板持液時，間歇精餾二元理想混合物，餾出液中輕組分極限濃度的數值計算方法。
  4. Bubble tower overhead

    泡罩塔頂餾分
