4.93. Liquid methanol is fed to a space heater at a rate of 12.0 L/h and burned with excess air. The product gas is analyzed and the following dry-basis mole percentages are determined: CH;OH = 0.45%, CO2 = 9.03%, and CO = 1.81%. (a) Draw and label a flowchart and verify that the system has zero degrees of freedom. (b) Calculate the fractional conversion of methanol, the percentage excess air fed, and the mole fraction of water in the product gas. (c) Suppose the combustion products are released directly into a room. What potential problems do you see and what remedies can you suggest?

Transcribed Image Text:4.93. Liquid methanol is fed to a space heater at a rate of 12.0 L/h and burned with excess air. The product
gas is analyzed and the following dry-basis mole percentages are determined: CH;OH = 0.45%,
CO2 = 9.03%, and CO = 1.81%.
(a) Draw and label a flowchart and verify that the system has zero degrees of freedom.
(b) Calculate the fractional conversion of methanol, the percentage excess air fed, and the mole
fraction of water in the product gas.
(c) Suppose the combustion products are released directly into a room. What potential problems do
you see and what remedies can you suggest?
