Problem 10.4: Your company faxed you some results, shown below, for the system hydrogen (1) / methane (2). Use these data to answer the following:
a) Because the fax machine malfunctioned, some entries were missing. Supply the missing numbers and explain your calculations.
b) What is the saturation pressure of methane at 250 K?
c) Calculate the fugacity of saturated liquid methane at 250 K.
d) Calculate the fugacity of methane at 250 K, 300 bar.
e) A solution with composition x1 = 0.2 is to be stored at 250 K. It is important to avoid the formation of vapor. What is the minimum pressure required?
f) Calculate the volume of the tank needed to store a saturated liquid mixture of the two components with composition x1 = 0.2 at 250 K. Report the result in cubic meters per million of mol.
