Because the compressors and expanders spin at speeds near 36,000 rpm, it is necessary to use speed reduction in gear-driven expanders systems. Typically, the gear reduction ratios vary from ∼10/1 to ∼20/1. Two types of gear systems are used. The most common are bull gear systems, although epicyclical gear systems can also be used
