    Abstract: A gas processing system includes a vessel defining a cavity for processing a gas. The vessel includes a process gas inlet for accepting process gas at an input pressure, and a process gas outlet for discharging process gas at an output pressure. The gas processing system further includes a shaft coupled to the vessel and a multistage sealing system comprising multiple seals spaced along the shaft. The shaft is configured to transfer mechanical energy to or from gas in the vessel. Each adjacent pair of seals defines a corresponding pressure space therebetween. One of the pressure spaces is an equalizing pressure space in hydraulic communication with the process gas inlet via a flow line, such that in operation, pressure in the equalizing pressure space is maintained at an equalized pressure with respect to a pressure in the process gas inlet.

    Abstract: A centrifugal compressor includes a rotation shaft, an impeller, a housing including a first chamber, a second chamber of which pressure is lower than the first chamber, and a partition wall that partitions the first chamber and the second chamber and includes a through hole through which the rotation shaft is inserted, and a seal member arranged in the housing. The seal member includes a gas seal and a support. When the rotation shaft is rotating, the gas seal surrounds an outer circumferential surface of the rotation shaft in a non-contact state in which dynamic pressure forms a gap between the gas seal and the outer circumferential surface of the rotation shaft. The support supports the gas seal in a state in which the gas seal is movable in a direction intersecting an axial direction of the rotation shaft.

    Abstract: A porous media ventless thrust bearing seal is disclosed. The porous media thrust bearing may include a primary porous media thrust bearing also serving as a seal ring including porous media positioned over a plenum and a port connected to the plenum, and conductive passages for communicating pressurized fluid to the plenums through the ports of the primary ring. The porous media ventless thrust bearing may also include a treated process gas supplied to a port which is closest to the untreated process gas, at a pressure which is higher than the untreated process gas. An inert gas (or fluid in a liquid state) may be supplied to the remaining port, at a pressure which is the same as the untreated process gas. A certain amount of treated process gas may flow into the untreated process gas, and may prevent the untreated gas from entering the porous media seal.

    Abstract: A fluid compression system is disclosed having a hermetically-sealed housing with at least a motor and a compressor arranged therein. The motor may drive both the compressor and a blower device coupled to the housing or otherwise arranged within the housing and configured to circulate a cooling gas throughout the housing and thereby cool the motor and accompanying radial bearings. The blower device circulates the cooling gas through a closed-loop circuit which may include a heat exchanger and gas conditioning skid. Buffer seals may be used to seal the shaft on both sides of the compressor so as to prevent the migration of liquid and solid contaminants into the closed-loop cooling circuit.
