2015-12-11 · The Unites States natural gas (NG) pipeline system is a complex network that relies on about 1800 compressor stations (CS) to maintain the pressure in the network. Concurrently, about two-thirds of the fuel energy to CS is lost as waste heat mainly in the form of hot flue gases. However, to date, there has been little emphasis on quantifying available waste heat at NG CS.
