The station there compresses the gas back to 1,435 psig, and it continues its journey downstream. All compressor stations on the Northern Border system are designed to operate unattended. Control equipment allows the operating functions of the station to be controlled remotely from Gas Control, a facility in Omaha, Nebraska. Although the stations may be operated remotely, each station is staffed with employees who perform routine operations and maintenance during normal working hours. About two miles of cable are contained in these trays.
Natural gas moves down the mainline toward the compressor station.
The closed block valve prevents the gas from continuing down the pipeline, and since gas naturally moves towards low pressure points, it is drawn into the stationthrough the open suction valve. The scrubber used centrifugal force to remove debris and liquids from the gas stream. Material that is heavier than the natural gas is spun out of the gas stream by the centrifugal force in the scrubber unit and drops into a holding tank. Scrubbers are installed at the first station downstream of gas receipt points. The gas generator is powered by natural gas obtained from a fuel tap on the pipeline.
