| dc.description.abstract | One of the most critical components of an LNG liquefaction facility are the refrigeration compressors and their drivers, which have a significant influence on overall plant performance and production efficiency. Refrigeration compressors for the train sizes referenced above are challenging to design due to large volume flows, high Mach numbers, low inlet temperatures, and complex side stream flows. Compressor drivers for these facilities include both heavy duty industrial and aeroderivative gas turbines that range in size from 30 MW to 120 MW, and several recently proposed projects are considering the use of large electric motor drivers up to 75 MW. This tutorial covers considerations in the design, application, and installation of refrigeration compressors in large LNG facilities. The paper does not focus on any specific LNG process technology but addresses turbomachinery design and application aspects that are common to all processes. Topics cover key technical design issues, complexities, and risks involved in compressor selection, aeromechanical design, testing, and installation and commissioning. Practical design compromises that must be made to obtain a robust compressor solution will be covered. | en |
