GROUP TASK

EACH GROUP CONTAINS MAX 3 PERSONS

1. For the gas composition given in the following text, determine apparent molecular weight,

specific gravity, pseudo-critical pressure, pseudo critical temperature of gas.

Component Mole Fraction

C1 0.775

C2 0.083

C3 0.021

i-C4 0.006

n-C4 0.002

i-C5 0.003

n-C5 0.008

C6 0.001

C7 0.001

N2 0.05

CO2 0.03H2S 0.03

2. After you determine Ppc and Tpc, determine Pseudo-Reduce Pressure and Pseudo-Reduce

Temperature. After that find the gas compressibility Factor using Standing Kartz Correlation

and Beggs Brill Correlation. (standing kartz chart is attached).
