Butane (C4H10) is burned with excess air. The exhaust gas from the combustion is analyzed and has the following composition: 4.5 mole% O2, 73.8 mole% N2, 11.824% H2O, 0.236 mole% C4H10, 8.48 mole% CO2, 1.16 mole% CO. Determine: 1. (8 points) The fractional conversion of C4H10 2. (8 points) The ratio of exhaust produced to C4H10 fed 3. (9 points) The percent excess air fed to the process. Draw a flow chart.

Liquid ethanol is fed to a space heater at a rate of 13.0 L/h and burned with excess air. The product gas is analyzed and the following dry-basis mole percentages are determined: CH3CH2OH = 0.45%, CO2= 9.03%, and CO= l.81 %.

(a) Draw and label a flowchart.

(b) Calculate the fractional conversion of ethanol, 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?

Please explain each steps.

Gas boiler uses methane (CH4) as its fuel source. As a newly appointed engineer, you are assigned by your superior to determine whether the current boiler operation is running at the optimum conditions. You are given the average daily Orsat gas analysis of the stack gas as shown in Table Q3.

Table Q3: Composition of Orsat stack gas.

Component Mol (%)

CH4 0.55

O2 12.00

N2 82.40

CO2 5.05

Given the element molecular weight of C=12, H=1, O=16 and N=14. Assume the air stream fed to the boiler only consists of 21 mol% O2 and 79 mol% N2. In order to perform the analysis, you need to solve few fundamental question below.

a. Write the main stoichiometric combustion reaction.

b. Draw the input-and output flowchart of the process.

c. By using element balances and taking 100 kmol/s of Orsat flue gas as the basis of calculation, determine the following:

i. The mass flow rate of natural gas into the boiler.

ii. The percentage of excess air used in the combustion

iii. The actual fractional conversion of methane

iv. The actual water produced.

v. Composition of stack gas in wet basis.
