Liquid methanol is fed to a space heater at a rate of 12.0 L/hr and burned with excess air. The product gas is analyzed and the following dry basis mole percentages are determined: CH₃OH: 0.45%, CO₂=9.03%, CO=1.81% (make sure you think about what else needs to be in the product gas).

a) (1 point) Draw and fully label a PFD

b) (2 points) Calculate the fractional conversion of methanol, the percentage excess air fed, and the mole fraction of water in the product gas.

c) (1 point) Suppose the products are released directly into a room. What potential problems do you see and what remedies do you suggest?

Expert Solution

Answer (c) When the products gas released directly int he room , than the amount of methanol , carbon dioxide and carbon monoxide increases in the room, these gases are undesirable in fresh air to breath. So potential problem of breathing will arise because of decrease in oxygen concentration. Also methanol is poisonous in nature.

So the space heater should be provides with stack so the flue gas released in ambient atmosphere outside the room. If this is not possible than we should provide proper veltilation in the room.

6.4 L/Hr of Isopropyl alochol is fed to a heater with pure Oxygen. the molar flow rate of Oxygen is twice that of the Isopropyl alcohol in the feed. The fraction conversion of O2 is .91. The ratio of CO2 to CO in the effulent stream is 15.5 to 2. Find the molar flow rate of all products in the effulent stream. Please show all work and draw a flow diagram for visual. Thanks

A 384.0 g/hr stream of liquid methyl alcohol, also called methanol, (CH3OH) at 7.60 atm and 10.0°C was held at constant pressure, vaporized and brought to 564.0°C. At what rate must heat be supplied to this system? Assume that methyl alcohol vapor behaves ideally for the temperature range and pressure given.

Methanol liquid burns readily in air. One way to represent this equilibrium is: CH3OH(l) + 3/2 O2(g) <-------->CO2(g) + 2 H2O(g We could also write this reaction three other ways, listed below. The equilibrium constants for all of the reactions are related. Write the equilibrium constant for each new reaction in terms of K, the equilibrium constant for the reaction above. 1) 2 CO2(g) + 4 H2O(g) <-----> 2 CH3OH(l) + 3 O2(g) K1 = 2) CO2(g) + 2 H2O(g)...
