本文提出尋求精餾系統最小回流比的新思路,并将它用于對二元精餾最小回流比的計算。
在化工分離工程領域,回流比(Reflux Ratio) 是精餾操作中的關鍵參數,定義為塔頂回流液體流量(L)與塔頂餾出液産品流量(D)的比值。其數學表達式為:
$$ R = frac{L}{D} $$
其中:
工程意義與作用:
權威定義參考:
該參數在石油煉制、化工分離及乙醇提純等工業過程中具有廣泛應用價值,其優化對節能減排至關重要。
Reflux ratio(回流比)是化工領域(尤其是蒸餾、分餾等分離過程)的核心參數,具體含義如下:
回流比指在分餾塔操作中,回流量(L)與餾出液量(D)的比值,即: $$ R = frac{L}{D} $$
