A distillation sieve-tray tower is being used to distill a hydrocarbon feed. The vapor flow rate at the tower bottom is 21 000 kg/hr and the liquid flow rate is 19 500 kg/hr. The density of the liquid rhoL = 673 kg/m3 and rhoV = 3.68 kg/m3. Assume a tray spacing of 24 in. (0.610 m). Calculate the tower diameter assuming the tower operates at 80% of flooding. Assume σ = 22.5 dyn/cm.
