Abstract: A system and method for sealing a shaft disposed for rotation within a casing, where two axially-spaced seal rings of an oil film seal extend around the shaft and define a clearance therebetween. Oil is pumped into the clearance from an oil reservoir and a portion of the oil is received in an annular port defined in the casing between an outer labyrinth seal and one of the axially-spaced seal rings. The oil mixes with a process gas to for an oil and gas mixture. A blower is in fluid communication with the annular port and circulates the oil and gas mixture to a trap where the oil is separated from the process gas and a separated process gas is returned back to the annular port.

Abstract: A method and system for expanding, separating, and compressing a multi-phase fluid. An expander receives and expands the multi-phase fluid to generate a lower-pressure fluid which can more efficiently be separated in a separator. Expanding the fluid also drives a main shaft adapted to drive at least the separator and a compressor coupled thereto. The separator receives the lower-pressure fluid, separates any higher-density components from the lower-density components disposed therein, and provides a substantially dry gas to the compressor to be re-compressed and discharged from the system.
