arrangementer control and operation of centrifugal gas compressors

About the course: This hands-on, three-day course uses dynamic simulation models to give a practical introduction to centrifugal gas compressors and their.
different control mechanisms (speed, variable vanes, recycle, throttling) are The performance of centrifugal gas compressors is best displayed in a map .. A compressor, operated at constant speed, is operated at its best efficiency point (Bottom) Compressor Arrangement after One of the Two Units. Fails at Time = 1.0.
A hands-on course using dynamic simulation models to give a practical introduction to centrifugal gas compressors, their performance characteristics and. An example of a performance map is given in Fig. Key topics covered in the course include compressor performance and selection, instrumentation and control, surge protection and compressor operation. The presence of discharge check valves also provides the benefit of isolating each of the antisurge recycle loops see the subsection on Antisurge Valves. Another arrangement is the mezzanine-mounted configuration. The stationary ring is backed by a quantity of toolbox bing site safety springs that force it tightly against the rotating disc when the compressor is at rest.

Excessive wear of the internal labyrinth seals can occur when the compressor experiences high vibration excursions from process upsets or operation in a surge condition. The compressor shown is mounted on a single baseplate and is driven by an electric motor. For variable speed compressors, the surge limit curve see Fig. Engineers with little previous knowledge of compressors who are involved in the design, control, operation or commissioning of process plants. Because the impellers rotate at high speeds, centrifugal stresses are an important design consideration, and high-strength steels are required for the impeller material.
