Migration of Existing Control System Tools to FDI

Since the announcement of the Field Device Integration effort at the Interkama/Hannover trade fair in 2007, many companies have contributed to the development of the Field Device Integration (FDI) standard, IEC 62769. This standard is scheduled to be released in 2015. One of the objectives of the ISA104 committee, Device Integration, is to adopt and …

Centrifugal Compressor Efficiency – Part 4

CompleteEff

Part 1 of the centrifugal compressor efficiency series addressed the measurements and parameters that must be calculated to determine compressor efficiency. In Part 2-3 of this series we examined one way of calculating the enthalpy and entropy of the gas stream at the compressor suction and discharge and isentropic enthalpy for the refrigerant R134a. Once …

Centrifugal Compressor Efficiency – Part 3

Entropy R134a

Part 1 of the centrifugal compressor efficiency series addressed the measurements and parameters that are used to calculate compressor efficiency. In Part 2 of this series we examine how these measurements are used to calculate the enthalpy of the gas stream at the compressor suction and discharged for the refrigerant R134a. This calculation utilized bilinear …

Centrifugal Compressor Efficiency – Part 2

R134a Thermodynamic Properties

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 …

Centrifugal Compressor Efficiency – Part 1

Measurements On-line Compressor Efficiency

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 …
