This course illustrates techniques of the high pressure, high discharge rats, re-cycle gas compressors. Components, Drivers, Operation, Performance and Maintenance of different types of the re-cycle compressors are explained. The basis surge control and vibration damping are also cleared.
This course is designed for Mechanical Engineers and Technicians who are looking for efficient running, maintaining of high rates, high pressure, re-cycle Compressors.
Descriptions of the compressor components, specifications.
Driver specifications ( direct drive and gear drive ).
Principles of start up and shut down of the recycle compressors.
Check up list of the compressor ; operating data, (bearings temperature, vibrations and damping system, lubrication, differential pressure across I/O filter, dry gas seal vent line pressure, differential pressure across buffer gas filter, differential pressure between buffer gas and reference gas ).
