Centrifugal compressor trains operating in parallel or series arrangements are complex when it comes to turbomachinery control. Methodologies for controlling compressor trains in these arrangements piping layout considerations ...

One of Du Pont's plants operates a 20,000 hp synchronous motor driven process air compressor consisting offour compression sections and three intercoolers (Figure 1). A six percent capacity increase from refitting the first ...

Synchronous machines produce an oscillating torque at twice slip frequency on starting. If the shaft system of a coupled compressor is not adequately designed, or if the motor malfunctions, this torsional excitation will ...

We introduce an efficient method to support generation of geometric winding paths on parametric shapes. Filament winding is a technology for producing composite materials by winding resin-infused fibers around the underlying ...

In recent years, power systems have undergone radical changes by becoming deregulated. Many electric companies have met new requirements and found ways to keep up with the changes in power systems. Issues of transfer ...
