Probllem#6 Given the analysis in the table below of a natural gas produced from an oil well, 1. Calculate the gas gravity and pseudo-critical T and P, 2. What volume will 100 lb of this gas occupy at P=3000 psig and T=170F ? 3. Calculate the gas density and specific volume at these conditions of P and T. 4. A 10ft cylindrical tank is filled with this gas at 2500 psig and 100F. a) How many moles of gas are in the tank? b) What standard volume (in SCF) of gas is in this? c) 750 scf of gas is released from the tank, this causes the temperature to fall to 60F. What is the final tank pressure? Component Mole Fraction, % 79.05 10.85 4.61 1.28 2.04 0.21 0.34 0.84 0.78 Mc-=140 SGC: -0.85
