Understanding Natural Gas Compressor Stations

Components of A Compressor StationPermitting and Regulatory FrameworkSafety ConsiderationsCommunity and Landowner ConsiderationsMunicipal and Zoning ConsiderationsRight of Condemnation Or Eminent DomainExtensionRoleResourcesNatural gas enters a compressor station through station yard piping and is passed through scrubbers and filters to extract any liquids and remove solids or other particulate matter that may be in the gas stream (Figure 1). Once the natural gas stream has been cleaned, it is directed through additional yard piping to individual compressors. Computers regulate the flow and number of units that are needed to handle the scheduled system flow requirements. Most compressor units operate in parallel, with the individual compressor units providing the needed additional pressure before directing the gas back into the pipeline with full operational pressure restored. When the required boost in pressure is very high, several compressor units may be operated in stages (serially) to achieve the desired pressure in stages. As natural gas is compressed, heat is generated and must be dissipated to cool the gas stream before leaving the compressor facility. For every 100 psi increase in pressure, th...Get price
