Question
Methane (CH4 ) and ethane (C2H6 ) are the primary constituents of "natural gas". Natural gas is often transported as a refrigerated liquid for shipment over long distances. In this problem I will ask you to find the total pressure above a liquid mixture composed of 75 wt% methane and 25 wt% ethane at a temperature of 150 K? Assume no other components are present in the system and that the liquid can be considered an ideal mixture.
To solve this problem, you will probably need to work out the vapor pressures of pure methane and pure ethane at 150 K.
Explanation / Answer
total pressure = 14.37atm
