(Batch distillation with constant reflux) A batch distillation column having a stillpotand one ideal tray separates a mixture of benzene and toluene. At the beginning there is10 kmol of liquid in the still with 40 mole% benzene. The rate of vapour generation is15 kmol/h and a reflux ratio of 3.0 is used. Determine the concentration of the overheadvapour and the instantaneous rate of removal of benzene. The relative volatility ofbenzene is 2.51.

Given data; Feed rate; F=10 kmol/hr Benzene concentration; Xf=0.4 Reflux ratio; R=LD=3 Relative…

A flow of 0.35 kg/s of a solid is to be dried from 15 per cent to 0.5 per cent moisture on a dry basis. The mean specific heat capacity of the solids is 2.2 kJ/kg deg K. It is proposed that a co-current adiabatic dryer should be used with the solids entering at 300 K and, because of the heat sensitive nature of the solids, leaving at 325 K. Hot air is available at 400 K with a humidity of 0.01 kg/kg dry air and the maximum allowable mass velocity of the air is 0.95 kg/m²s. What diameter and length should be specified for the proposed dryer?
