Introduction

This course is to provide the trainees with a strong background in the field of compressors structures, types and maintenance as well as the compressor troubleshooting. The emphasis is placed on understanding the maintenance of the different types of compressors and the different methods of bearing, sealing and lubricating systems, and axial thrust prevention methods.

Centrifugal Compressors a play a very essential role in many petrochemical and industrial plants. Centrifugal compressors  in general runs at very high speeds, exposed to high temperature. The compressor operation is confined between the Surge and Stonewall limits.

The compressor performance also is affected by the variation in operating conditions. Elevated temperature and large centrifugal stresses make the gas turbine operating under very critical conditions requires very complicated monitoring and protection systems. The above very sever operating conditions enhances the machines deterioration. Accurate instrumentation, monitoring, troubleshooting and maintenance programs are essential for maintaining and increasing the available time of the machines. Understanding and learning Centrifugal compressors more deeply help smooth and free trouble operation.

During the course the design, performance, operation limits and control system are going to be addressed thoroughly. Parameters affects the above will also be discussed during the course.

Objective

By end of course participants will be able to understand

  • Familiarize participant of different  compressors design.
  • Learn how different design parameter affects the machines performance  and operation.
  • Familiarize participant of the different types of gas compressors and  their  application
  • To deepen the participants understanding of the limits of the compressor  operation.
  • Enable participants to read and calculate the performance curves of compressor
  • To familiarize the participant with control, and protection systems of centrifugal compressor systems.
  • To familiarize the participant to start and shut down the compressor in smooth and properly methods.
Audience

Maintenance, Process and Mechanical engineers & technicians are involved with types, maintenance, construction, and troubleshooting, of Compressors. Entry level engineers, technicians all the way to senior level will benefit because of the course structure.
