Chapter 9, Problem 9.77P
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.
- Calculate the temperature and the degrees of superheat of the reactor effluent. (Consider water to be the only condensable species in the effluent.)
- Suppose only 15% excess air is supplied. Without doing any additional calculations, state how the temperature and degrees of superheat of the reactor effluent would be affected [increase, decrease, remain the same, cannot tell without more information] and explain your reasoning. What risk is involved in lowering the percent excess air?

Methylamine is used in the manufacturing of several various pharmaceutical products. Atone facility, there is a 2000 lbm tank of methylamine. If the entire tank is releasedcontinuously during a 20-minute time period, determine the concentration in ppm at adistance 1 mile directly downwind. Does this exceed published exposure limits formethylamine? Assume the release is at ground level, and it is an overcast night with a 5mph wind.
Emergency response for the rupture of an ammonia pipeline is being planned. Themaximum estimated flow rate from the rupture is 20 kg/s. Local authorities havedetermined that evacuations are necessary if the concentration exceeds the ERPG-2 level.Assume a temperature of 20˚C, wind speed of 3 m/s, atmospheric pressure of 1 atm, 70%cloud cover and rural conditions. State any other assumptions.a. How far directly downwind needs to be evacuated?b. Using a spreadsheet (such as excel), draw a plot of the isopleth at thisconcentration. You should have at least 8 different distances downwind markedon your plot.
A reactor in a pesticide plant contains 8000 lbm of a liquid mixture of 50% by weightmethyl isocyanate (MIC). The liquid is near its boiling point. A study of various releasescenarios indicates that a rupture of the reactor will spill the liquid to a boiling pool onthe ground. The boiling rate of the MIC has been estimated to be 50 lb m/min. Evacuationof the population must occur in areas where the vapor concentration exceeds ERPG-3levels. If the wind speed is 10 mph on a clear winter night, estimate the distancedownwind that must be evacuated.
