Efficient and reliable subsea compression system

摘要

A system, method, and apparatus for compressing a process fluid are provided. The system includes a sealed housing configured to be submerged in a body of water, and a compressor disposed in the sealed housing and including a compressor casing, the compressor being configured to compress a process fluid. The system also includes a motor operably coupled to the compressor and disposed in the sealed housing, the motor being configured to drive the compressor. The system further includes a source of hydrogen, such as a hydrogen generator, disposed in the sealed housing or submerged and disposed proximate thereto, the source of hydrogen being fluidly coupled with the compressor and configured to provide the hydrogen gas thereto.

1. A compression system, comprising:
a sealed housing configured to be submerged in a body of water; a compressor disposed in the sealed housing and including a compressor casing, the compressor being configured to compress a process fluid; a motor operably coupled to the compressor and disposed in the sealed housing, the motor being configured to drive the compressor; a source of hydrogen disposed in the sealed housing or submerged and disposed proximate thereto, the source of hydrogen being fluidly coupled with the compressor and configured to provide hydrogen gas thereto; anda gas-gas cooler configured to transfer heat from the motor to the process fluid, wherein:
the source of hydrogen is fluidly coupled with the motor and configured to provide hydrogen gas thereto; the gas-gas cooler comprises a first flowpath directly fluidly coupled to the compressor, and a second flowpath directly fluidly coupled to the motor; the first flowpath is arranged to discharge the process fluid from the gas-gas cooler directly to the compressor; the second flowpath is arranged to transport the hydrogen gas directly from the motor to the gas-gas cooler and to discharge the hydrogen gas from the gas-gas cooler directly to the motor; and the compressor casing defines a compressor outlet, and the compressor is further configured to discharge the process fluid directly from the sealed housing via the compressor outlet.
