Assume that the gas in the line in Exercise 8.1 condenses 0.01 GPM (1.41 m3 liquid/106 Nm3 gas) over the 8 mi (12.9 km) distance and the line is pigged once a day. How many gallons (m3 ) of condensate would the pig remove from the line?

Exercise 8.1

 A 6 in. pipe (cross-sectional area = 0.2006 ft2 (0.01864 m2 )) gas line transports 20 MMscfd (0.536 × 106 Nm3/d). An 8 mi (12.9 km) segment of the line is pigged. Assuming that the average pipeline temperature is 80°F (27°C) and average operating pressure is 250 psig (17.2 barg), what would be the average pig speed (mph, km/h) in the line and the minimum time it would take to traverse the pigged segment? Assume ideal gas behavior and that there is minimal gas slippage around the pig.
