Mitsubishi Heavy Industries Compressor Corporation (MCO), a wholly-owned operating company of Mitsubishi Heavy Industries, Ltd. (MHI), was inaugurated in April 2010 following the integration of MHI’s process compressor business operations and MHI Turbo-Techno Co., a company supporting the compressor business in the after-sales service and training areas.
Horizontal split centrifugal compressor
Multiple impellers are attached to a single rotating shaft, for a multi-stage structure. The gas enters through the intake nozzle, and is compressed and pressurized by centrifugal force as it passes through the impellers, which are rotating at high speed, before being ejected through the ejection nozzle. With this type of compressor, the outer casing can be split in the horizontal direction, facilitating the maintenance of internal parts.
Vertical split centrifugal compressor
With this type of compressor, the outer casing is a single continuous cylinder, for a structure which is capable of withstanding high pressures of approximately 50 – 700 bar, or 1000 bar in trials. The internal bundle (diaphragm and shaft) can be pulled out in the axial direction for maintenance.
Integrally Geared Compressor
The multi-shaft, multi-stage structure contains a cascade of gears, with the wheel gear and the multiple pinion gears on the outside of it driving multiple impeller shafts. By changing each of the gear ratios, it is possible to operate each impeller at the optimal speed, for high-efficiency operation.
