摘要：Compressors achieve in a single stage a high-pressure ratio () 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 rially to increa 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/cond into a diffur passage of the outlet. Dimension ranges of the annular diffur passage, the centrifugal impeller, and the diffur vanes vary as a function of pressure ratio () and/or the flow coefficient (φ) of the process fluid flowing between the inlet and the outlet.
