Centrifugal compressors are used in a large number of different compression application. This tutorial addresses applications for centrifugal compressors in the upstream and midstream sector, such as LNG compression, ...

Mixed operation with both centrifugal and reciprocating compressors in a compression plant poses significant operational challenges as pressure pulsations and machine mismatches lead to centrifugal compressors’ instabilities ...

For every centrifugal compressor installation, the design of the surge control system is vitally important to prevent damage of the compressor internal components, seals, and bearings. While most surge control systems are ...

Industrial gas turbines show performance characteristics that distinctly depend on ambient and operating conditions. They are not only influenced by site elevation, ambient temperature, and relative humidity, but also by ...

Industrial gas turbines allow operation with a wide variety of gaseous and liquid fuels. To determine the suitability for operation with a gas fuel system, various physical parameters of the proposed fuel need to be ...

This tutorial explains the surge phenomenon as well as the precursors of surge and the damage that surge can cause to the equipment. Then, methods to keep the compressor system from surge, i.e., modern surge control systems, ...

Power enhancement technologies for gas turbines such as inlet fogging, interstage water injection, saturation cooling, inlet chillers, and combustor injection are being used by end users without evaluating the potentially ...

Field testing of compressor packages driven by gas turbines or electric motors requires the accurate determination of efficiency, flow, head, and power in sometimes less than ideal working environments. This paper discusses ...

The power and efficiency characteristics of a gas turbine are the result of a complex interaction of different turbomachines and a combustion system. This tutorial addresses the basic characteristics of each of the components, ...
