High reliability and reduction of life cycle costs are valued in centrifugal compressors used in the oil and gas industry. These centrifugal compressors are required to maintain high efficiency and obtain wide operating range to cope with changes in load based on future demands. This paper provides an impeller development that has achieved high efficiency and a wide operating range. It also outlines IGV control system development to achieve the power saving at low load requirement. This IGV technology developed can be applied in a wide variety centrifugal compressors as well as for cryogenic application.
