WebApr 5, 2024 · Since V = D(R + 1), where R is the reflux ratio, then the cost of the column is: The annual cost of the reboiler and the condenser, ch per mole of distillate may be written as: where cb is the annual cost of the heat exchange equipment per unit area including depreciation and interest and Ah is the area for heat transfer. 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 ... screenagers ceu
