Abstract
A system for automatically evacuating liquids from natural gas pipelines. An embodiment may be used for associated drip vessels and other containers and gas wells. The system includes a tank, a compressor, and an electric generator system. The system evacuates liquid from a pipeline by creating a pressure differential between the pipeline and the tank. When adequate pressure differential is achieved, liquids flow into the tank from the pipeline. When liquids are removed, the system shuts down and awaits a run signal. The system is suited for remote locations, due, in part, to the use of an automatic generator capable of providing power to the compressor and to the CPU as necessary. Liquid removal may be determined by measuring tank pressure at time intervals and determining a rate of change of tank pressure for indicating blow through. The system utilizes the same pipeline tap for liquid removal and gas injection.
