Product Name: Elliott Multi-Stage Centrifugal Compressors

Product Description

Through extensive research in the fields of rotor‑dynamic stability, aerodynamic cross-coupling stiffness, and rotor-bearing systems, we have developed proprietary analytical tools. Incorporating these developments into Elliott compressor designs has produced a number of product enhancements. For example, we’ve increased rotor stiffness by increasing shaft diameter, reducing impeller weight, and increasing journal bearing sizes. This allows higher torque transmission capabilities and higher‑speed operation, with improved rotor stability characteristics, which are essential as gas densities and operating pressures increase.

Elliott uses state-of-the-art interactive design and prediction tools to optimize aerodynamic performance and increase flange-to-flange efficiencies. Compressor impeller and matched stationary flowpath components are developed using Computational Fluid Dynamics (CFD) analyses and other current design tools. Three-dimensional blade profiles, diffuser flow angles, crossover bend curvature, area ratio, and return channel vane shapes are optimized for each impeller stage to provide the best possible efficiency. Additional performance enhancements are achieved by improving the flow distribution channels at the inlet and discharge volutes and sidestream mixing areas. These enhancements allow us to provide some of the industry’s highest operational efficiencies.
