Abstract
This paper describes the various types of centrifugal compressor used in process plants, and continues to discuss the more important components of these compressors and particular design features which are required to overcome some difficult operational problems. Items of particular interest include a discussion on the latest form of compressor rotor construction, the techniques required for balancing a rotor at full speed, and a detailed analysis of shaft gas seals and problems that can arise with gas seals under certain operating conditions.
The paper also describes such special subjects related to process plant compressors as compressor selection and design by utilization of computers, methods of reducing time to produce compressor orders by discrete stockholdings; types of driver and shaft couplings used for these machines, and test facilities employed for centrifugal compressors which can be utilized to reduce commissioning periods at site.
