Abstract: An expander and motor-compressor unit is disclosed. The unit includes a casing and an electric motor arranged in the casing. A compressor is arranged in the casing and drivingly coupled to the electric motor through a central shaft. Furthermore, a turbo-expander is arranged for rotation in the casing and is drivingly coupled to the electric motor and to the compressor through the central shaft.

Abstract: The LNG plant comprises a compression train and a further compression. The compression train (100) comprises comprising an engine and a compressor driven by the engine; the compressor is an axial compressor and comprises a first set of axial compression stages and a second set of axial compression stages arranged downstream the first set of axial compression stages; at least the first set and the second set of axial compression stages are housed inside one case. The further compression train comprises a further engine and a further compressor driven by the further engine; the further compressor is a centrifugal compressor and comprises a first set of impellers and a second set of impellers arranged downstream or upstream the first set of impellers.

Abstract: The centrifugal compressor has a housing with two or more compressor inlets for process gas to be compressed; an impeller is located inside the housing so to receive an inlet flow of process gas from the two compressor inlets through a plenum chamber and increases gas pressure as process gas flows in the impeller thanks to the two or more inlets uniformity of flow at the inlets may be achieved through short collector pipes fluidly connected upstream of the inlets piping of a compressor system including such compressor is made easy as it is subject to fewer constraints.
