The best operating condition lies between minimum and total reflux. As a rule of thumb, the optimum reflux ratio lies between 1.05 and 1.25 (L/D)min. Too low of an L/D results in a large number of

WebThe reflux ratio is kept constant so the liquid flowing down has uniform flow and only the power input to the reboiler can be adjusted. The boil-up rate is obtained by varying the heat energy to the reboiler and this affects the velocity of the vapour passing up the column. As the velocity of the vapour passing up the column increases, the ...
