How to Use Turboexpanders in Energy Recovery

November 22, 2019

The article “ How to Use Turboexpanders in Energy Recovery “ on page 32 of Turbomachinery International discusses the role of turboexpander generator in natural gas pressure letdown stations and how it reduces gas pressure and converts the resulting kinetic energy into electrical energy. The article introduces Calnetix’s FreeSpin In-line Turboexpander™, an oil free hermetically sealed solution for reducing pressure in gas processing and distribution systems while generating clean power. The hermetically sealed unit consists of an integrated high-speed turboexpander and a permanent-magnet generator, both driven by a single spinning rotor levitated on non-contact magnetic bearings.
