Concept explainers
(a)
Interpretation:
Mole fraction of hexane in condenser feed&product gas stream.
Concept introduction:
Stream of N-hexane in methane entering at 60 °C and 1.2 atm
Dew point of gas = 55 °C
Pure hexane as a liquid is recovered by cooling of gas at 5°C.
Cooling gas leaves condenser at 5°C and 1.1 atm and fed to boiler furnace at 207.4 L/s.
It is burnt with 100%excess air which is at 200°C.
Stack gases at 400°C and at 1 atm with no CO2 and unburned hydrocarbon.
Liquid water at 25°C is converted to saturated steam at 10 bars due to heat transfer.
(b)
Interpretation:
- Rate of heat transfer in KW
- Rate of steam generation in kg/s
Concept introduction:
By using conduction equation, we will find you the rate of heat transferred.
Rate of heat transfer is calculated in Joules (J).
Rate of heat transfer is given by (Q/t).
