Ethane (C2H6) is combusted in 18.1% excess oxygen (O2) in an adiabatic reactor. The feed of ethane enters the reactor at 25.8 mol/hr and 93.7°C. The stream exiting the reactor contains ethane, oxygen, carbon dioxide (CO2), carbon monoxide (CO) and water (H2O), so ethane reacts by both complete and partial combustion reactions. The conversion of ethane is 15.8% and the conversion of oxygen is 12.3%. Assume that pressure effects are negligible. (a) Draw and label a process flow diagram. Number each stream and label the components (E=ethane; O2=oxygen; CO2=carbon dioxide, CO=carbon monoxide; W=water). (b) Calculate the component molar flow rates (mol/hr) for all of the exiting components. (c) Calculate the adiabatic flame temperature (°C) for the reactor. (d) If the reactor's insulation is damaged and the reactor could lose heat to the surroundings, would the exit temperature increase, decrease, or stay the same?

Ethane (C2H6) is combusted in 18.1% excess oxygen (O2) in an
adiabatic reactor. The feed of ethane enters the reactor at 25.8
mol/hr and 93.7°C. The stream exiting the reactor contains ethane,
oxygen, carbon dioxide (CO2), carbon monoxide (CO) and water (H2O),
so ethane reacts by both complete and partial combustion reactions.

A 2.20 g sample of the Ethane C2H6 gas was mixed with excess
oxygen gas and a combustion reaction occurred to obtain water in
liquid aggregate and carbon dioxide state. The combustion reaction
occurred at a constant calorimeter under standard conditions.
After the reaction was completed, the temperature in the
calorimeter rose by 1.3K. The heat capacity of the calorimeter is
88.8 kJ / K.

place.
2. Consider the...

100 moles of ethane (C2H6) are burned with
50% excess air. The percentage conversion of the ethane is 90%; of
the ethane burned, 25% reacts to form CO and the balance reacts to
form CO2. Calculate the molar composition of the stack
gas on a dry basis and the mole ratio of water to dry stack
gas.

Methane is burned with 25% excess air in a continuous adiabatic
reactor. The methane enters the reactor at 25 C and 1.10 atm at a
rate of 550 L/s, and the entering air is at 150 C and 1.1 atm.
Combustion in the reactor is complete, and the reactor effluent gas
emerges at 1.05 atm.

reactor effluent. (Consider water to be the only condensable
species in the effluent)....

Water (H2O) is split into hydrogen (H2)
and oxygen (O2) in a reactor. While only water enters
the reactor, the conversion is incomplete. So all three components
exit the reactor.
