Boil up rate and column efficiency
WebThe Reflux ratio is the ratio between the boil up rate and the take-off rate. Or in other words, it is the ratio between the amount of reflux that goes back down the distillation column and the amount of reflux that is collected in the receiver (distillate). Webboil-up ratio. The ratio of vapour returned to the bottom of a distillation column to the bottom product removed. ... Access to the complete content on Oxford Reference …

WebApr 30, 2013 · The boil-up rate,V, without reflux is: V = Q/λ (21) At total reflux, the reboiler heat duty is: Q = V (λ + Ht (22) where H is the liquid specific heat andtsub is condenser subcool in °C. The batch time, θbatch, at constant reflux ratio is given by: θbatch = [ (R +1)/V] (S0 – S1) = λ/V (23) TYPICAL AGITATOR CONSTANTS Table 1.
