A certain amount of 1000ppm contaminant y must be removed from an organic solvent by hydrogenation in a falling film reactor at atmospheric pressure. The reaction is elementary and can be represented in equation below: y+H2P Gas mixture of 25%H2 in N2 flows from the bottom of the reactor with constant velocity (g) of 0.5cms1. The mass transfer of H2 is sufficiently fast and remains in equilibrium in liquid phase of organic solvent that flows inside the reactor with average velocity of (l)15 cms1 to form liquid film of 2mm thickness on the wall. The column is operated at 25C and has 300cm length and 10cm diameter. a) Determine the concentration of H2 if the contaminant y is being removed continuously starting from 70% removal until the end of reaction, with interval increment of 5%. Give your comments on the answer obtained. b) Determine the effect of contaminant y removal if the velocity of liquid (l) is increased to 20cms1 and support your justification by using the design equation below: dZdCy=[(D02Di2)1.07CH2H2] where; Cy is concentration of contaminant y C2 is concentration of H2 in liquid phase Z is length of reactor D is diameter of column falling film reactor Given: Molecular weight of organic solvent (MW): 80.1gmol1 Henry's Law constant of H2:1103atm Density of organic solvent ():0.75gcm3 Universal gas constant, R:82.06cm3atmmol1K1
