Chemistry

A fuel gas containing methane and ethane is burned with air in afurnace, producing a stack gas at 300.°C and 105 kPa (absolute).You analyze the stack gas and find that it contains no unburnedhydrocarbons, oxygen, or carbon monoxide. You also determine thedew-point temperature.

(a) Estimate the range of possible dew-point temperatures bydetermining the dew points when the feed is either pure methane orpure ethane.

(b) Estimate the fraction of the feed that is methane if themeasured dew-point temperature is 59.5°C

(c) What range of measured dew point temperatures would lead tocalculated methane mole fractions within 5% of the value determinedin Part (b).
