Abstract
Practical recommendations on modern compressor casing, impellers, shaft, internals, material selection, control system, surge prevention systems, diaphragms, casing connections, nozzle loads, bearing, and balance piston are explained. This article highlights the lessons learned from several industrial experiences in relation to the selection, design and manufacturing of compressor components especially critical parts such as dry gas seals, seal support systems, control units and surge prevention systems for the centrifugal compressors. Particularly the tandem type seal is discussed in detail. Case studies are presented.
