  • Patent number: 10711789
    Abstract: A shaftless motor-compressor is disclosed, comprising a casing and at least one compressor stage arranged in the casing. Each compressor stage comprises a respective impeller arranged for rotation in the casing around a rotation axis. Each impeller is combined with an embedded electric motor housed in the casing and comprised of a motor stator and a motor rotor. The motor stator of each compressor stage circumferentially surrounds the impeller and the motor rotor, integral with the impeller. The motor rotor of each stage is arranged inside the respective motor stator.

  • Patent number: 10634157
    Abstract: A centrifugal compressor impeller comprises a gas inlet, a gas outlet, and a disc having a plurality of blades extending therefrom. Each blade has a leading edge at the impeller inlet and a trailing edge at the impeller outlet, a blade base extending along the disc between the leading edge and the trailing edge, a blade tip extending between the leading edge and the trailing edge opposite the disc, a pressure side and a suction side. Each blade has a three-dimensional curvature in at least a portion of the surface, adjacent the leading edge. The leading edge has a curved, non-linear profile in a meridian plane. The blade portion has a double-curvature. Each blade has a first metal angle distribution at the blade base, a second metal angle distribution at the blade tip and at least a third metal angle distribution between the blade base and the blade tip.

  • Patent number: 10570923
    Abstract: A scroll for use in conjunction with a fluid compressor is described. The scroll comprises a fluid inlet adapted to receive a fluid flow and a fluid outlet adapted to discharge the fluid flow. The scroll further comprises a scroll-shaped wall defining an inner flow volume. At least one blade is provided in the inner flow volume of the scroll. The blade is configured and arranged for correcting a direction of the flow of fluid in the flow volume when the scroll is operating in off-design conditions.

  • Publication number: 20190136862
    Abstract: A system and modular compressor for raising the pressure in production gas is disclosed, wherein in a set of compressor modules each second module is a rotor module carrying an impeller driven in rotation relative to an adjacent stationary module, a rotor module and a stationary module in combination providing a compressor stage in which production gas is accelerated through a flow duct that passes an interface between the rotor module and the stationary module, wherein at the interface at least one bearing for axial and/or radial load is provided for journaling the rotor module on the stationary module. The at least one bearing is a gas bearing, wherein a passage is arranged in the stationary module to lead an extracted portion of production gas at raised pressure from the compressor to the gas bearing(s).
