Abstract
A turbocompressor for use with a process fluid and including an axial expansion turbine for expanding the process fluid and a centrifugal compressor for compressing the process fluid. The turbine and compressor share a common shaft, all of which can be housed by a common housing that encloses sealed spaces. The axial expansion turbine has a rotor located between two main bearings, and the centrifugal compressor includes an impeller mounted to one end of the shaft. In one embodiment, the main bearings are lubricated by a portion of the process fluid so that the only fluid in the sealed spaces is the process fluid. The turbocompressor can be used in a power-cycle system that includes a heat source and, optionally, an electrical generator.
