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?
