Abstract: A diffuser for a compressor includes an annular diffuser passageway defined by a hub wall and a shroud wall of a housing of the compressor. The annular diffuser passageway may be fluidly coupled with a centrifugal impeller configured to rotate with a rotary shaft of the compressor about a center axis. The diffuser may also include a plurality of low solidity diffuser vanes extending into the annular diffuser passageway from the hub wall or the shroud wall and arranged annularly about the center axis. The diffuser may further include a plurality of high solidity diffuser vanes disposed radially outward from the plurality of low solidity diffuser vanes and extending into the annular diffuser passageway from the hub wall or the shroud wall and arranged annularly about the center axis.

Abstract: A system and method are provided for a compression system. The system and method may include a driver having a drive shaft extending therethrough. The driver may be configured to provide the drive shaft with rotational energy. The system and method may also include a first single-stage compressor and a second single-stage compressor, each having a rotary shaft coupled with or integral with the drive shaft. The first and second single-stage compressors may be configured to compress a high molecular weight process fluid to provide a compressed process fluid having a pressure ratio of about 10:1 or greater. The compressed process fluid may contain heat from the compression thereof. A heat recovery system may be fluidly coupled with the first and second single-stage compressors and may be configured to receive the compressed process fluid and absorb at least a portion of the heat contained in the compressed process fluid.

Abstract: A system and method are provided for detecting an impending stall or surge in a radial compressor. The system and method may include a plurality of detection devices configured to detect a transition of a low momentum zone of a gas flow through the diffuser from a first position adjacent a shroud wall of the diffuser to a second position adjacent a hub wall of the diffuser. The system and method may also include a control system electrically coupled to the plurality of detection devices and configured to receive a plurality of information signals. Each information signal may be transmitted by a respective one of the plurality of detection devices and may correlate to a location of the low momentum zone. The control system may be configured to process the plurality of information signals and detect the impending stall or surge based on the location of the low momentum zone.
