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.
