Description

How They Work

1. 1. Impeller: At the heart of a centrifugal compressor is the impeller, a rotating disk with curved blades. As the impeller spins, it draws in the fluid at its center.
   2. Acceleration: The blades accelerate the fluid, increasing its velocity and kinetic energy.
   3. Diffusion: The fluid then enters a diffuser section, where the passage area increases. As the fluid moves through the diffuser, its velocity decreases and its pressure increases due to the principle of conservation of energy.
   4. Discharge: The pressurized fluid is discharged from the diffuser.

Advantages of Centrifugal Compressors

• High flow rates: Capable of handling large volumes of fluid.
• Relatively simple design: Fewer moving parts compared to other compressor types.
• Continuous operation: Can operate continuously for extended periods.
• Smooth operation: Generally produce less vibration and noise.
• Wide range of applications: Suitable for various fluids and operating conditions.

Applications

• • • Petroleum industry: Compressing natural gas and refinery gases.
    • Chemical industry: Compressing process gases.
    • Power generation: Used in gas turbines for power generation.
    • Refrigeration: Compressing refrigerants in large-scale refrigeration systems.
    • Air conditioning: Providing compressed air for HVAC systems.
