DeltaV Blog: Centrifugal Compressor Efficiency – Part 2

Terry Blevins

As addressed in Part 1 of the centrifugal compressor efficiency series, the enthalpy of the gas stream at the compressor suction and discharge must be known to determine the compressor efficiency. Also, the isentropic enthalpy must be determined based on the gas stream entropy at the compressor suction and the compressor discharge pressure. These properties … Continue reading » Read the full text.

DeltaV Blog: Centrifugal Compressor Efficiency – Part 1

Terry Blevins

Centrifugal compressors play an important role within the process industry. In some cases compressor capacity may determine the throughput of a plant. If a compressor is used for refrigeration then any variation in compressor operation may directly impact the temperature control in key unit operations such as flash vessels and exothermic reactors. Also, the compressor … Continue reading » Read the full text.

DeltaV Blog: How to Succeed – Part 6

Gregory K McMillan

The increased emphasis on minimizing leakage, energy use, and low cost bid has lead to increased process variability. The valve with the lowest leakage, pressure drop, and price tag often has deadband, rangeability, resolution, and sensitivity deficiencies leading to poor control creating continual oscillations even when there are no process upsets. The sustained equal amplitude … Continue reading » Read the full text…
