(5) Consider the emissions from a manufacturing process. These emissions contain three gaseous pollutants in the following proportions by volume: 50% of VOC-1, 30% of VOC-2, and 20% of VOC-3. The emission gases pass through a carbon adsorption air pollution control unit the retains 97% of VOC-1 and negligeable amounts of VOC-2 and VOC-3. At the end of 6 hours of operation, exactly 0.5 kg of the VOC-1 are recovered. a) Draw a mass balance diagram of the scenario b) Determine the mol/hour flowrate of the gas stream entering the adsorption unit c) Calculate the volume % of VOC-1 in the exit gas stream
