This tutorial covers the basics, applications, and operation of compressors, expanders, steam turbines, and gas turbines in refinery applications. Modern refineries utilize a wide range of turbomachinery that must flexibly ...

Meeting current rotordynamics stability standards CO2 Compressors High flow coefficient/Mach number impellers Coupling and alignment impacts on asymmetric rotordynamics Sour gas/Chloride implications on material ...

One of the foremost concerns facing rotating equipment users today is that of torsional vibration. In contrast to lateral vibration, torsional vibration is rarely monitored. As a result, torsional failures can be especially ...

Acceptance criteria for high-speed balancing of turbomachinery are specified in API standards based on either pedestal velocity or shaft displacement. In addition to performing balancing, the measured displacements can ...
