6. An absorber packed to the height of 5 m, is currently being used to remove a volatile
organic chemical (VOC) pollutant from an exhaust stream. Fifteen cubic meters per
minute of gas at 289°K and 1.013x 105 Pa, containing 5.0 mole % VOC is fed to the
bottom of the absorber tower. By feeding a non-volatile, VOC – free solvent stream
to the top of the tower, the VOC concentration is reduced to 0.3%. The solvent stream
leaves the bottom of the tower containing3.65 mole % VOC. At the pressure and
temperature of the tower, the equilibrium for the VOC – solvent system may be
represented by YA = 0.8XA. The cross section area of the tower is 0.2 m2. Determine
the molar composition of the liquid stream flowing counter current to the gas stream
at the point in the tower where the bulk gas composition is 2.5% VOC. [ 16 ]

a 5 cm ID steel pipe. The reservoir and the overhead tank are open to the atmosphere,
and the difference in vertical elevation between the water surface in the reservoir and
the discharge point at the top of the overhead tank is 20 m. The length of the pipeline
is 300 m. Two gate valves and three standard 90° elbows are included in the system.
The efficiency of the pump is 40%. This includes losses at the entrance and exit of the
pump housing. If the flow rate of water is to be maintained at 50 gpm (1m3 = 264
