An evaluation of the possibilities of using turboexpanders at pressure regulator stations
Abstract
Natural gas in Poland is transported by onshore pipelines with a maximum operating pressure of up to 8.4 MPa. The gaspressure is then reduced to 1.6 MPa or 0.4 MPa for delivery to regional/local distribution networks or to end-user installations.The pressure reduction is usually performed by a pressure regulator. Pressure reduction can also be achieved throughexpansion of the gas at the turboexpander, which can be harnessed to produce electricity from the recovered mechanicalenergy of the gas. The main objective of this study is to investigate the factors influencing the efficiency of the gas expansionprocess and to carry out a feasibility study involving the application of turboexpanders at selected natural gas pressureregulator stations belonging to the Polish transmission system operator Gaz System S.A.References
