本文提出寻求精馏系统最小回流比的新思路,并将它用于对二元精馏最小回流比的计算。
在化工分离工程领域,回流比(Reflux Ratio) 是精馏操作中的关键参数,定义为塔顶回流液体流量(L)与塔顶馏出液产品流量(D)的比值。其数学表达式为:
$$ R = frac{L}{D} $$
其中:
工程意义与作用:
权威定义参考:
该参数在石油炼制、化工分离及乙醇提纯等工业过程中具有广泛应用价值,其优化对节能减排至关重要。
Reflux ratio(回流比)是化工领域(尤其是蒸馏、分馏等分离过程)的核心参数,具体含义如下:
回流比指在分馏塔操作中,回流量(L)与馏出液量(D)的比值,即: $$ R = frac{L}{D} $$
