Centrifugal Compressors

Centrifugal integrally geared compressors have been commissioned in a multitude of process applications in the gas, oil and chemical industries. Whether your workflow requires a high-pressure compressor for flash gas, gas recycling or any number of other specialized applications, these products deliver the reliability and uptime assurance that our customers demand. These low-flow, high-speed compressors provide pulsation and oil free flow in a compact design whose integrally geared configuration delivers clear operational advantages over traditional reciprocating and screw type designs. Plus, the compressors are built to API-617 / 614 ratings, meaning that our products are engineered to last and require minimal maintenance running for 7 years without an overhaul.

The compressors are primarily used for continuous, stationary service in the oil refineries, chemical and petrochemical plants and natural gas processing plants. Their application can be from 100 (75 kW) to 4,000 horsepower. Multiple compressors chained together on a single integrally geared.

Application:

• Corrosive gases, Polypropylene, Regeneration, Recycle, Vapor recovery, Fuel gas, LNG, Ethylene, Acetic Acid, Acetylene, Hydrogen Feed for refining, Waste gas recycles, Lift gas, Atomizing Air, Chlorine, Gas Boost, Polysilicon production

Centrifugal compressors, sometimes called impeller compressors or radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.

They achieve pressure rise by adding energy to the continuous flow of fluid through the rotor/impeller. The equation in the next section shows this specific energy input. A substantial portion of this energy is kinetic which is converted to increased potential energy/static pressure by slowing the flow through a diffuser. The static pressure rise in the impeller may roughly equal the rise in the diffuser.
