Natural gas pipeline in the chemical industry
High accuracy custody transfer measurement
Large volumes of natural gas are transported using high pressure transmission pipelines, delivering to power plants, LNG liquefaction plants, large industrial users and city gates. Compressor stations along the pipeline maintain the flow, and the line pressure - at around 60bar: these stations normally use gas from the pipeline to power the compressor. If the gas is to be used in a local gas grid, the pressure would be reduced to around 8 bar at the city gate in a pressure regulating station.
