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: Systems and methods are provided for sidestream mixing. The system may include a first junction formed from a plurality of conduits. The plurality of conduits may include a first conduit fluidly coupled to a compressor, the first conduit forming a first conduit diameter and configured to flow therethrough a first process fluid stream of a plurality of process fluid streams. The plurality of conduits may also include a second conduit fluidly coupled to the first conduit and the compressor, and configured to flow therethrough a second process fluid stream of the plurality of process fluid streams. The first junction may be disposed a first distance at least three times the first conduit diameter upstream of the compressor, such that the first process fluid stream and the second process fluid stream are mixed and form a first combined process fluid stream prior to being fed into and pressurized in the compressor.

Abstract: A compressor performance adjustment system includes a compressor chassis defining an inlet passageway, a diffuser passageway coupled to the inlet passageway, and a return passageway extending from the diffuser passageway. At least one inlet vane is located in the inlet passageway. At least one diffuser vane is located in the diffuser passageway. At least one return vane is moveably coupled to the compressor chassis and located in the return passageway. Via a system of rods and actuators, the return vanes may be adjusted without disassembling the compressor chassis in order to adjust the flow incident on compressor components and adjust the performance of a compressor.
