About the Course:

  The course will introduce delegates to the various types of compressors and associated terminology. Centrifugal and positive-displacement compressors, packing, mechanical seals and sealing systems, bearings and couplings will all be discussed.
The application of the different types of compressors will be discussed along with their suitability for different operational duties. Compressor operation, troubleshooting and maintenance will be dealt with in depth.

Course Objectives:

   The main objective of the course is to Carry out preventive, predictive and corrective maintenance on Process gas compressors (centrifugal, axial and screw types).

   The course covers how these machines work on process, mechanical aspects, wear, lubrication and troubleshooting by vibration analysis and other techniques. The course provides participants with knowledge for inspecting and monitoring compressors, and details how to make fault detections and diagnoses. Emphasis is placed upon the importance of a combined condition monitoring and strip-down inspection approach to maintenance. Extensive use is made of case study material to underline the key aspects of the course and to give the delegates exposure to current best practice.

    At the end of this seminar participants will have:
              • An understanding of the different types of Gas compressors.
              • Will be able to monitor compressor efficiency, availability and reliability.
              • The ability to confidently overhaul the subject Off Gas Compressors.
              • Be able to troubleshoot compressor problems.
         Designed for:
            • This course is intended for engineers, supervisory Foremen Mechanical

               Maintenance, Supervisor / Foreman / Senior Foreman, and technical

                staff involved in the maintenance and inspection of Process Gas compressors.

            • The course will also benefit anyone who expects to become involved

               at any stage in project applications and applicable maintenance

               technologies. The course will also benefit anyone who wishes to update

               themselves on compressor technology, judge the suitability of different

                types of compressors for their needs, and learn how to operate and maintain

               them for the benefit of their Organizations.
