Wet air containing 4.0mole% water vapor is passed through a column of calcium chloride pellets. The pellets adsorb 97.0% of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of 3.40kg, following 5.0 hours of operation the pellets are reweighed and found to have a mass of 3.54 kg.
(a) Calculate the molar flow rate (mol/h) of the feed gas and the mole fraction of water vapor in the product gas.
(b) The mole fraction of water in the product gas is monitored and found to have the value calculated in part (a) for the first 10 hours of operation, but then it begins to increase. What is the most likely cause of the increase? If the process continues to run, what will the mole fraction of water in the product gas eventually be?
The Cookenwythe Gas Company pumps propane gas to the nearby Noxious Chemicals, Inc., polypropylene production plant. The gas is metered at the noxious plant at 400m3/h at 4.7atm gauge and 30°C.
Consider an ordinary, helium-filled party balloon with a volume of 2.2ft3 . The lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon.
Perform the material balance and energy balance calculations for the process on the basis of 100 kg magnetite charged. Also
Defluorination & adhesion properties, Using ion bombardment-If Teflon is deflorinated to increase it's adhesion properties, then what would the changes in surface characteristics be?
The chemical reactor shown below has a cover (called a head) that is held in place by a series of bolts. The head is made of stainless steel (SG = 8.0), is 3 in. thick, has a diameter of 24 in., and covers and seals an opening 20in. in diameter.
Determine the standard heats of Reactions. Discuss the purpose of feeding oxygen to the reactor. Assuming no heat is lost to the surroundings, estimate the temperature of the gas and slag leaving the gasifier.
The data in Table 1 were obtained from a kinetic study of an enzymatic reaction. The substrate S (with a concentration s) was converted, using an enzyme, to a product in 4 different experimental runs. The initial conditions of each experiment (initia..
50. Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor. The fresh feed to the process contains 32.0 mole% CO, 64.0% H2, and 4.0% N2. This stream is mixed with a recycle stream in a ratio S mol recycle/1 mol fresh feed to..
