What are the advantages and disadvantages of centrifugal …

WebCentrifugal compressors run at speeds between 20,000 and 30,000 RPM. They are typically engine or turbine driven. Turbines are commonly used due to high rotating speeds. Centrifugal compressors are used in pipeline booster service where high volume and low compression ratios exist. They are also used in very high flow rate gas lift service. WebSchultz (1962) developed a centrifugal compressor model that takes into account the actual behavior of the gas that is being compressed by making use of the polytropic head factor, which corrects the assumption that the polytropic coefficient is constant throughout the compression process.
