Abstract: A system and method for supplying clean dry gas to gas seals of a compressor. The system uses a rotary separator magnetically coupled to a source of rotational power, along with a gas stream cooling unit configured to condensate liquids out of a wet gas stream before the wet gas stream is supplied to the rotating separator. The system may further include a gas stream pressure booster, a heating unit to heat a dry gas stream generated by the rotary separator, and a controlled recirculation loop configured to continually recirculate the wet gas through the driven rotary separator until a desired amount of condensates are removed from the wet gas stream.

Abstract: A fluid deflector is for a fluid separator including a central axis and an enclosed wall having an open end and an inner circumferential separation surface extending about the axis to define an interior separation chamber. The fluid deflector includes a base disposeable proximal to the wall open end and having a central axis collinear with the separator axis. A plurality of vanes are connected with the base so as to be spaced circumferentially about the central axis. The vanes define a plurality of flow channels each bounded by a separate pair of adjacent vanes and having an inlet and an outlet. Each vane directs flow through a bounded channel generally radially inwardly from the channel inlet toward the channel outlet and generally circumferentially and radially outwardly from the channel outlet.

Abstract: An inlet valve system (10), as may be used for a cylinder chamber (20) of a compressor, such as a reciprocating compressor, is disclosed. A plurality of inlet valves (250) is movable between an open position and a closed position. The plurality of inlet valves is arranged between an unloader chamber (120) and a cylinder chamber (20) of the compressor. A control valve (270, 270') is coupled to a controller (300) and is movable between a first position and a second position to close the inlet valves. A check valve (260, 260') is movable between a first position and a second position to open the inlet valves. The check valve and the control valve are respectively fluidly coupled to a control chamber (252), which is decoupled from any pressure control external to cylinder chamber (20).
