A mixture of hydrocarbons has the following molar composition: 1% methane, 15% ethane, 25% propane, 14% isobutane, 25% n-butane, 20% n-pentane, for a total of 100%.

a) What temperature is required to condense 40% of the total moles at 100 psia? b) What temperature is required to condense 100% of the steam? c) If 100,000 ft3 at Standard Conditions (C.E.) of the original gas is introduced into a flash separator at 100 psia and 90F:  What size should be the pump that will handle the liquid from the separator, Express the size of the pump in gallons per minute (GPM).  NOTE: Rackett's equation can be used to estimate the molar volume of saturated liquid (equation 3.72 page 109 Smith & Van Ness) d) Which substance has the greatest effect on the bubble point and which has the greatest effect? above dew point.
