Chapter 10, Problem 126IE
Natural gas is very abundant us many Middle Eastern oil fields. However, the costs of shipping the gas to markets in other parts of the world are high because it is necessary to liquefy the gas% which is mainly methane and has a boding point at atmospheric pressure of —164 °C. One possible strategy is to oxidize the methane to methanol. CH3OH. which has a boiling point of 63°C and can therefore be shipped more readily. Suppose that 10.7

A sample of propane (C3H8)(C3H8) is placed in a closed vessel together with an amount of O2O2 that is 3.10 times the amount needed to completely oxidize the propane to CO2CO2 and H2OH2O at constant temperature.
Calculate the mole fraction of each component in the resulting mixture after oxidation, assuming that the H2OH2O is present as a gas.
To evaluate the use of renewable resources, an experiment was carried out with rice hulls. After pyrolysis, the product gas analyzed 6.4% CO2, 0.1% O2, 39% CO, 51.8% H2, 0.6% CH4, and 2.1% N2. It entered a combustion chamber at 90 °F and a pressure of 35.0 in. Hg and was burned with 40% excess air (dry) at 70 °F and an atmospheric pressure of 29.4 in. Hg; 10% of the CO remains.
a. How many cubic feet of air were supplied per cubic foot of entering gas?
b. How many cubic feet of product gas were produced per cubic foot of entering gas if the exit gas was at 29.4 in. Hg and 400 °F?
1)The production of authentic tequila is restricted to the blue agave and a defined geographical area in west-central Mexico. Two basic categories of tequila can be distinguished: “100% agave” and “mixed” tequila. High-quality “100% agave” tequila uses pure agave juice for fermentation and Mexican law states that these authentic tequilas must be bottled in Mexico. A mixed tequila is manufactured by adding up to 49% (w/v) of sugar from sugar cane for fermentation. The low-quality tequila is usually shipped in bulk containers for diluting and bottling in the importing countries. Due to frequent fraud in the labeled quality of tequila, there is a need to verify the authenticity of a tequila using chemical analysis. Figure 1 shows an ion chromatogram for an authentic 100% agave tequila and a commercial mixed tequila. The difference in anion content is due to the different sources of water used in final dilution and bottling steps.
