Course Description

This seminar entails a study of gas compression and expansion laws applied to industrial processes followed by an illustration of the different types of rotating machines usually encountered in plants , and their related aspects. The aim is to provide a satisfactory approach to the problems posed by compressors and turbines and the means to solve them.


Course Objective

At the end of this seminar participants will have:

·         An understanding of the construction and operational constraints of centrifugal compressors and steam turbines.

·         Knowledge of how to optimally maintain the equipment for the benefit of the company

·         Hints and Tips for practical application of monitoring technologies so as to achieve the best results.



Who Should attend?

This seminar is directed towards Supervisors, Team Leaders and Managers in Maintenance , Engineering and Production . The seminar will also benefit anyone who wishes to update themselves on Centrifugal Compressors and Steam Turbines, judge the suitability of them for their needs, and learn how to operate and maintain them for the benefit of their organisations
