Dynamic Analysis of a Multi-Stage Compressor Train

Abstract

Technical Brief 4: A complex multiple-stage compressor train which is part of an off-shore booster installation was facing process and mechanical related problems. The frequency of these problems has increased lately leading to frequent trips and shut downs. These interruptions affect the operation of the plant and resulted in a loss in production and a subsequent loss of revenue to the company.<br.<br>The platform contains two similar compressor trains consisting of a four-stage compressor with a gas turbine driver. Each train is fitted with an integrated turbine compressor control panel. Thus, a detailed dynamic system simulation of the subject compressor trains was performed in order to provide a series of recommendations that would improve the safe operation and increase the reliability of the compression systems. Thus, results of the analysis and some of the recommendations obtained are presented in this case study.
