Abstract: A sealing assembly configured to seal a rotating shaft of a turbo machine having a high pressure process gas, comprising a housing defining a bore configured to receive the rotating shaft and sealing assembly, wherein the housing is mounted to a casing of the turbo machine; a first sealing stage comprising a single dry gas seal and configured to blow down the high pressure process gas to a lower pressure; a labyrinth seal mounted longitudinally outward from the first sealing stage; and a second sealing stage mounted longitudinally outward from the labyrinth seal, wherein the second sealing stage comprises a tandem dry gas seal having a primary dry gas seal and a secondary dry gas seal axially spaced with an intermediate labyrinth seal.

Abstract: A closure device for a compressor having at least one access opening, wherein the closure device includes a plug portion disposeable at least partially within and configured to substantially obstruct the at least one access opening, a head portion having a shoulder surface extending generally radially outwardly with respect to the plug portion, wherein the head portion is generally disposeable against an inner surface of the compressor and configured to maintain the plug portion disposed within the at least one access opening during compressor operation, and a retainer member having a bracket engageable with an outer surface of the compressor and a threaded rod extending between the bracket and the plug portion, wherein the retainer member is configured to retain the plug portion disposed within the at least one access opening.

Abstract: A fluid channeling device including a channeling body, an axial transfer channel, and a radial outlet channel. The channeling body includes first and second annular body sections spaced axially apart and a tubular body section extending between the first and second body sections. The axial transfer channel is defined axially through the channeling body, and is configured to fluidly couple a first compression assembly with a second compression assembly. The radial outlet channel is defined radially through the channeling body and is configured to fluidly couple the second compression assembly with an outlet.

Abstract: A closure device for a casing having at least one access opening wherein the closure device includes a cover member movably disposed within an interior chamber of the casing so as to be slidably displaceable along or in the direction of a casing central axis between an open and a closed position, the cover member being spaced at least partially axially from the access opening in the open position so as to permit access to the interior chamber and generally extending across and substantially obstructing the at least one access opening in the closed position.

Abstract: A shaft support device for a turbomachine including a rotary body and a stationary body. The rotary body is attached to a shaft of the turbomachine, and includes a first portion and a second portion. The first portion has a thrust bearing collar and the second portion has a thrust balance piston. The first and second portions are axially overlapping. The stationary body is fixably attached to a casing of the turbomachine. The stationary body has a first thrust bearing portion that is disposed adjacent to and operatively engages the first portion of the rotary body.
