transportation and processing of gas to extract NGL. The following example
details the calculations of GPM for a typical gas.

Problem 3—Calculation of Gallons Per Thousand
for Gas Condensate

The separator gas from a gas condensate field with the composition given in
Table 5.15 is processed through a lean oil plant. Calculate the NGL recovery
for each component. Molecular weight of C7 1 is 120 lbm/lbm mole and
specific gravity of C7 1 is 0.72. Assuming 25% recovery for ethane, 70%
