SABIC plans to build a packed distillation column for separating methanol

SABIC plans to build a packed distillation column for separating methanol from water. The feed flow rate is 1000kmol/ day. The feed is saturated liquid and contains 40mol% methanol. An external reflux ratio of 2 is to be used. The pressure inside the column is 1atm (assume it is constant). The mole fractions of methanol in the distillate and bottoms are 0.998 and 0.0001 , respectively. The column is to be designed at a vapor flow rate that is 80% of flooding. You can take water viscosity at 100C to be 0.26cP. Calculate the diameter of the column at the bottom if the packing to be used is: a. 1-inch ceramic Berl saddles b. 1-inch plastic Intalox saddles SABIC plans to build a packed distillation column for separating methanol from water.
