Abstract: A pipeline pig launching system for a gas pipeline, including a pressure bottle, a two-chambered drip leg, and a pig launcher barrel. Condensate from the gas in the pipeline collects in the upper chamber of the drip leg and flows through an equalizer line to the lower chamber.

The pig in the launcher barrel is then pushed into the pipeline at a point downstream from the drip leg. A booster line may also be included in the system to provide a direct connection between the outlet of the pressure bottle and the inlet of the pig launcher barrel.
