In a typical process equipment for glycol dehydration, the gas flows through a separator to remove condensed liquids that might be in the gas. Lean, water-free glycol is fed to the top of an absorber where it is contacted with the wet natural gas stream containing 0.15 mole fraction of water vapor at the inlet. The total gas flow rate is 34.50mole/m2s and the diethyleneglycol (DEG) entering is 88.90mole/m2s. The DEG removes 97% of water and the dry natural gas leaves the top of the absorption column and is fed to a gas plant. The equilibrium condition is given as y=1.75x. The glycol absorbers uses a certain type of packings which provides an overall gas-phase mass transfer coefficient (Kya) of 46mole/m3s. Neglecting changes in gas and liquid flow rates, calculate the following: (i) Driving force at the top and bottom of column (i) Number of transfer units required in the gas phase (ii) Height of the transfer unit and the total height of the tower (Z) (iii) Percent of the total resistance in the gas phase if kya=65mol/sm3
