The oxidation of ethylene to produce ethylene oxide proceeds according to the equation2C 2H 4 +O 2 ! 2C 2H 4OThe feed to a reactor contains 100 kmol C 2H 4 and 100 kmol O 2. If the reaction proceeds to completion, how much of the excess reactant will be left; how much C 2H 4O will be formed; and what is the extent of reaction?
Cereal is being dried in a vertical drier by air flowing countercurrent to the cereal. To prevent breakage of the cereal flakes, some of the exit air from the drier is recycled back to mix with the the moist fresh air. For each 1000 kg/hr of wet cereal fed to the drier, calculate the input of moist fresh air in kg/hr and recycle rate in kg/hr. The available data on stream compositions is (fractions): For water: Fresh air: 0.0132 Wet cereal: 0.200 Exit air: 0.263 Dried Cereal: 0.050 Air entering Dryer: 0.066
The following gas-phase reaction takes place in a closed, constant-volume batch reactor at isothermal (constant temperature) conditions. 2CO+O2→2CO2 Initially, the reactor contains 0.564 kmol of CO, 1 kmol of O2, 1 kmol of CO2, and 0.5 kmol of N2 at a total pressure of 5 atm. Assuming ideal gas behavior, what is the reactor pressure (in atm) when the reaction goes to completion?
A fuel contains 78wt% carbon and 22wt% hydrogen (H).

The feed to the reactor contains 10 mol/min C2H6 and 200 mol/min air. The percentage conversion of ethane is 80%, and the gas leaving the reactor contains 8 mol CO2 per mol of CO. Determine the molar flow rate of the ethane gas in the product stream. (2 mol/min)
A mixture containing 42 wt% benzene (B) and 58 wt% toluene (T) is fed to a distillation column at a flow rate of 100 kg per minute. The product steam leaving the top of the column (the overhead product) contains 90 wt% benzene and 85 wt% of the total benzene fed to the column exits in this overhead product stream. Calculate the mass flow rate and mass composition of the product stream leaving the bottom of the column. Calculate the volumetric flow rate of the overhead product, assuming that it exits the distillation column as a vapour stream at 82C and 1 atm (abs).

- The major objective of a roasting process is to eliminate the Sulphur contained in the concentrate andto provide a calcine. In a roasting plant, 1000 kg per hour of molybdenum(IV) sulphide (MoS2) is roastedwith 25 % excess air to obtain MoO3 calcine in a chamber-type roasting furnace. Preheated air entersthe reactor at 400 K while MoS2 enters at room temperature. After the process, the waste gases leavethe reactor at 1000 K, and the calcine leaves at 850 K.a) Draw process flowsheet and heat balance diagram (ref. temp is 298 K) b) Calculate the amount of off-gas per hour in moles. c) Calculate the amount of calcined MoO3 per hour in kg.

Electrolytic manganese dioxide can be prepared from manganese carbonate ore by crushing,milling and leaching the ore in sulphuric acid. Manganese sulphate is crystallised from thesolution, redissolved and electrolysed to give the manganese dioxide.If the crystallisation were performed in a 30m3 tank and the concentration of the solutionentering the tank were 160 grams per litre and left the tank at 40 grams per litre, how muchMnSO4.5H2O would be produced.
