  • In-line electric motor driven compressor
    Patent number: 6261070
    Abstract: The present invention relates to an in-line electric motor driven compressor station that uses an in-line electric motor driven compressor to transport gas through a pipeline. This station can operate with greater flexibility and reduce costs because either axial or centrifugal compressors can be used, the motor can be immersed in the gas stream or cooled by air, and the station can actually be used to generate electricity. While overcoming the deficiencies of conventional compressor stations, an in-line electric motor driven compressor station offers operators a longer lasting, improved way to maintain the necessary pressures in a gas pipeline.
