Abstract: A shroud for a compressor is provided. The shroud may include an inner annular member and an outer annular member. The inner annular member may include an abradable material disposed between a first end portion and a second end portion thereof. The inner annular member may further be contoured between the first end portion and the second end portion thereof. The inner annular member may be configured to be disposed proximal an impeller of the compressor such that the inner annular member and the impeller define a clearance therebetween. The outer annular member may extend axially from the second end portion of the inner annular member. The outer annular member may be configured to compliantly mount the shroud with a casing of the compressor.

Abstract: A mounting assembly for assembling a bundle of a compressor is provided. The mounting assembly may include a plurality of biasing members and a mechanical fastener. The plurality of biasing members may be disposed in a recess formed in a first annular body of the bundle, and may be configured to apply a biasing force to a second annular body of the bundle. The mechanical fastener may extend through a mounting flange of the second annular body and the plurality of biasing members. The mechanical fastener may be configured to couple the first annular body with the second annular body such that the first annular body and the second annular body define an axial gap therebetween.

Abstract: A balance piston seal assembly for a balance piston of a compressor is provided. The balance piston seal assembly may include a balance piston seal, a stationary support, and a gripping assembly disposed between the balance piston seal and the stationary support. The balance piston seal may be configured to be disposed about the balance piston such that an inner radial surface of the balance piston seal and an outer radial surface of the balance piston define a radial clearance therebetween. The stationary support may be configured to be coupled or integral with a casing of the compressor. The gripping assembly may be configured to secure the balance piston seal with the stationary support and to maintain concentricity between the balance piston seal and the balance piston during thermal radial expansion of the balance piston seal relative to the balance piston.

Abstract: A compressor may include a casing defining a discharge cavity and a seal cavity. A rotary shaft may be disposed in the casing, and a shaft seal assembly may be disposed in the seal cavity and about the rotary shaft. An impeller may be coupled with and configured to be driven by the rotary shaft. A balance piston may be integral with the impeller and may define the discharge cavity and the seal cavity. A balance piston seal may be disposed about the balance piston such that the balance piston seal and the balance piston define a radial clearance therebetween. The radial clearance may be configured to provide fluid communication from the impeller to the discharge cavity. A heat shield may be disposed in the discharge cavity, and may be configured to prevent the conduction of heat from the discharge cavity to the seal cavity via the casing.

Abstract: A supersonic compressor including an inlet configured to receive and flow therethrough a process fluid. The supersonic compressor may further include a rotary shaft and a centrifugal impeller coupled therewith. The centrifugal impeller may be configured to impart energy to the process fluid received and to discharge the process fluid therefrom in at least a partially radial direction at an exit absolute Mach number of about one or greater. The supersonic compressor may further include a static diffuser circumferentially disposed about the centrifugal impeller and configured to receive the process fluid therefrom and convert the energy imparted. The supersonic compressor may further include a collector fluidly coupled to and configured to collect the process fluid exiting the diffuser, such that the supersonic compressor is configured to provide a compression ratio of at least about 8:1.
