A fresh feed of butanol (B, C4H9OH), oxygen (O2), and nitrogen (N2) is mixed with a recycle stream and fed to a reactor overseen by Romana and Boswell. The flow rate of the fresh feed is 507 mol/hr with mole fractions of 0.057 for butanol, 0.539 for oxygen, and the balance nitrogen. The reactor effluent contains butanol, oxygen, nitrogen, CO2, NO2, and water (W, H2O), which is fed to a separator. A gas stream containing oxygen, nitrogen, CO2, NO2, and some of the water exits the separator, and a butanol/water stream also exits the separator. Ninety-five times more water exits the separator in the gas stream than exits the overall system in the purge stream. The overall conversion of butanol is 78%, and the single pass conversion of butanol is 55%. The component flow rates of oxygen and nitrogen leaving the separator are 38.4 mol/hr and 155 mol/hr, respectively. In the last level, the overall system was solved.

A fresh feed of butanol (B, C4H9OH), oxygen (O2), and nitrogen (N2) is mixed with a recycle stream and fed to a reactor overseen by Romana and Boswell. The flow rate of the fresh feed is 507 mol/hr with mole fractions of 0.057 for butanol, 0.539 for oxygen, and the balance nitrogen. The reactor effluent contains butanol, oxygen, nitrogen, CO2, NO2, and water (W, H2O), which is fed to a separator. A gas stream containing oxygen, nitrogen, CO2, NO2, and some of the water exits the separator, and a butanol/water stream also exits the separator. Ninety-five times more water exits the separator in the gas stream than exits the overall system in the purge stream. The overall conversion of butanol is 78%, and the single pass conversion of butanol is 55%. The component flow rates of oxygen and nitrogen leaving the separator are 38.4 mol/hr and 155 mol/hr, respectively.
In the last level, the overall system was solved. Component molar flow rates were found in units of mol/hr as: n˙4,CO2 = 90.2, n˙4,NO2 = 99.6, n˙4,W = 111.5, n˙6,B = 6.36, and n˙6,W = 1.174.
Now, find the component molar flow rate (mol/hr) of the feed to the reactor
