Abstract: A fluid compression system is disclosed having at least a compressor and a motor (or alternate driver) arranged within a hermetically-sealed housing. The motor rotates a shaft upon which the compressor is disposed, and the shaft is supported within the housing by first and second radial bearings arranged at first and second ends of the shaft, respectively. An intermediate radial bearing is also arranged on the rotatable shaft between the first and second radial bearings. The radial bearings can be active magnetic bearings and controlled by two sets of channels in a bearing control system in order to levitate and control the position of the shaft.

Abstract: Compressors achieve in a single stage a high-pressure ratio ( r ) of greater than or equal to 2.5:1 on a process fluid having a molecular weight of 12-20, such as natural gas. Two or more of the compressor stages are combined serially to increase overall pressure ratio. Each single-stage includes respective inlet and outlet passages and an unshrouded, centrifugal impeller that includes a plurality of impeller blades. Process fluid is discharged from trailing edges of the impeller blades at a rotational velocity greater than or equal to 1400 feet/second into a diffuser passage of the outlet. Dimension ranges of the annular diffuser passage, the centrifugal impeller, and the diffuser vanes vary as a function of pressure ratio ( r ) and/or the flow coefficient (φ) of the process fluid flowing between the inlet and the outlet.

Abstract: A "bolt on" static separator is disclosed for use in conjunction with a rotating separator to handle higher liquid volumes that are not able to be effectively separated by the rotating separator alone. The static separator may be positioned upstream of the rotating separator, generally right in front of the rotating separator, i.e., immediately ahead of the inlet to the rotating separator and generally attached directly to the front end of the rotary separator. The static separator may include a significant change in flow path direction that is sufficient to cause coarse fluid separation. The output of the static separator is in communication with the input of the rotating separator. Additionally, the drain of the static separator is in communication with the drain of the rotating separator and is at the same pressure.
