Natural gas can travel through thousands of miles of pipeline. In order to avoid pressure reductions and the resulting slowdowns caused by distance, friction, and elevation, natural gas must be pressurized. Compressors placed at key intervals keep the natural gas moving evenly and reliably. These compressors are generally grouped in stations, which are strategically located along the pipeline networks that transport and store the gas.
A typical compressor station consists of an inlet scrubber to collect liquids and slugs that may have formed in the gas pipeline. These compressor scrubbers have a primary section where liquids and solid parts are separated from the gas stream, and a secondary section where oil mist is removed.
