7.44 (Packed height and HETP)2 An aqueous solution of methanol (30 mol% methanol; 2000 kg/h) is to be separated in a 0.7 m diameter packed tower to yield a distillate having 97% methanol and a bottom product having 4% methanol. The following values of the volumetric mass transfer coefficients are supplied. Rectifying section k = 800 K = 170 kā = 1250 Stripping section Ka=255 kmol/(m³)(h)(Ax or Ay) A reflux ratio of 1.4 times the minimum may be used. Calculate the height of the packed section. Also determine the HEPT of the packing.
