A feed stream containing 80 mole % n-butane, 5 mole % iso-butane and 15 mole % H20 is continuously heated at 1 bar in a heating unit from 50°C (input) to 75 °C (output). a) Energy Balance Question: Write an energy balance on the heater and use it to determine the required heat input to the stream, taking a basis of 100 mol/s of feed gas, b) Material Balance Question: The heated feed stream from the heating unit enters a reactor where n-Butane is converted to iso-butane in a continuous isomerization reactor (1:1 stoichiometry ratio; H2O does not participate in the reaction) and 70% conversion of n- butane is achieved. Taking a basis of 100 mol/s of feed gas, calculate the extent of reaction, 5, and the moles of each component in the product mixtures. Note: In terms of calculation, part b of this question is independent of part a, so you should be able to answer partb regardless of the answer to part a.

Question
Transcribed Image Text:A feed stream containing 80 mole % n-butane, 5 mole % iso-butane and 15 mole % H20 is
continuously heated at 1 bar in a heating unit from 50°C (input) to 75 °C (output).
a) Energy Balance Question: Write an energy balance on the heater and use it to determine
the required heat input to the stream, taking a basis of 100 mol/s of feed gas,
b) Material Balance Question: The heated feed stream from the heating unit enters a reactor
where n-Butane is converted to iso-butane in a continuous isomerization reactor (1:1
stoichiometry ratio; H2O does not participate in the reaction) and 70% conversion of n-
butane is achieved.
Taking a basis of 100 mol/s of feed gas, calculate the extent of reaction, 5, and the moles
of each component in the product mixtures.
Note: In terms of calculation, part b of this question is independent of part a, so you should be able
to answer part b regardless of the answer to part a.
