Can a continuous distillation column achieve a steady state at …

WebThis column is used to separate 5000 kg/h of a mixture containing 60 wt% benzene and 40 wt% toluene. Top product purity is 99.995 wt% benzene and 99.99 wt% toluene in bottom product. Feed temperature is 50 0 C and reflux ratio for the column is 1: 3. Column is operating at atmospheric pressure. WebExplain the following: overhead vapor rate, reflux rate, reflux ratio, and total reflux. Overhead vapor rate - the rate at which the vapor leaves the top tray Reflux rate - the rate of liquid … WebNo, total reflux condition is not possible. The total reflux in general an operating situation in the column where the two states of a matter such as vapor and liquid are passes by each other and in this situation no product is reduced. Where, R = L/V = ∞ and D = 0. The slope value in the operating line is, L/V = 1.0. ingles health
