A packed column is used to remove toluene from water by stripping with air. The water contains 60 ppm toluene and the concentration must be reduced to 2 ppm. The column will operate at an average pressure of 1.1 atm. Get the equilibrium relationship from the posted document henry.pdf.
a. Determine the minimum air rate in gmol/min for a water rate of 100 L/min.
b. Calculate the overall number of transfer units based on the liquid phase for an air rate twice the minimum.
c. Determine the packed height if Hy = 0.7 m and Hx = 0.6 m.
Then determine the approximate maximum angle through which the vehicle will rotate during powered flight, assuming no drag. Discuss the result.
Then, for 0.75 atm, plot the total energy needed versus ignition time. Give an interpretation of the results and trend for each of the two curves.
In a device to produce potable water, humid air at 90°F, 29.7 in Hg, and 95% relative humidity iscooled to 40°F at constant pressure. What volumetric flow rate of air into the cooler (ft3/min) isrequired to provide 10.0 gal/min of condensed water?
What is the maximum time interval until the first addition of inhibitor?
In the chlorination of ethylene to produce dichloromethane (DCE), the conversion of ethylene is reported as 99.0%. If 94 mol of DCE are produced per 100 moll of ethylene reacted, calculate the selectivity and the overall yield based on ethylene. T..
For the following reactions:a. Specify which of the following equations represent oxidation-reduction reactions. b. Write the balanced half-reactions for the reactions you identified as redox in part a. c. Identify the species being oxidized and th..
One type of commercial smoke detector contains a minute amount of radioactive americium-241 (241Am), which decays by -particle production. The particles ionize molecules in the air, allowing it to conduct an electric current. When smoke particle..
What does LD 50 mean in Industrial Toxicology and What is its significance to workers handling pesticides What units are used to quantify the standard service illuminance for specific work activities? Name the instrument used to appraise the lig..
At ground level in Denver, Colorado, the atmospheric pressure and temperature are 83.2 kPa and 27 C. Calculate the pressure on Pike's peak at an elevation of 2690 m above the city assuming temperature at Pike's peak is 16 C.
Calculate the heat when 100.0 mL of 0.500 M HCl is mixed with 300.0 mL of 0.100 M Ba(OH)2. Assuming that the temperature of both solutions was initially 25.0C and that the final mixture has a mass of 400.0 g and a specific heat capacity of 4.18 J..
The March 1979 accident at the Three Mile Island nuclear plant occurred due to a series of operator errors and equipment failures, which reduced the flow of cooling water to the reactor core. As a result, the water began to boil and the core reached ..
