To increase their shelf life and enhance their flavour, harvested tea leaves are processedthrough a drying process. Consider that picked tea leaves consist only of solid and water, with amoisture mass content of 60%. Commercial demand requires producing 160kg/hr with areduced moisture content of 5%.Determine the mass rate of water removed in the drying process

6) Flash Distillation Model ... Suppose we decide to distill the same 1000 moles of the 82 mole% cyclohexane and 18 mole% toluene mixture (see the Batch distillation problem) over a ten hour period (one day) using a flash distillation. In this case we would have a feed stream of 88.3 moles/hr and a bottoms flow rate of 11 moles/hr in order to achieve the same overall material result. A cyclohexane-toluene xy-equilibrium figure is provided for your use if needed. 0 a) For the flash option, determine the distillate and bottoms compositions. b) What would you recommend - batch or flash? Why? F=√+L zF=Y₂V*XBL F= = 1000 moles x=0.82 d=0.883 Xb= 0.117 BUF 0.020 SE301 2ACT 32581 2.12 S884
