How to Address Vibration in a Turboexpander Equipped with Active Magnetic Bearings

Turbomachinery International – March/April 2020 Tadeh Avetian, Luis E. Rodriguez and Junyoung Park How to Address Vibration in a Turboexpander Equipped with Active Magnetic Bearings L.A. Turbine and Samsung engineers discuss the diagnostic process and root cause analysis findings leading to the redesign of the active magnetic bearing turboexpander.

48th Turbomachinery & Pump Symposia Proceedings

Featured in the 48th turbomachinery pump symposia on September 2019 Addressing High Sub-Synchronous Vibrations in a Turboexpander Equipped with Active Magnetic Bearings This paper presents the authors’ experience with a turboexpander (TEX) equipped with active magnetic bearings (AMBs) in a natural gas processing facility.

Pushing the envelope

Recent technological developments within the world of turboexpanders (TEXs) promise to make the utilisation of active magnetic bearings (AMBs) even more widespread across all gas-related industries, and to allow end-users and engineering, procurement and construction (EPC) companies the opportunity to benefit from the competitive advantages AMBs offer.

Qualified Active Magnetic Bearing Retrofits for Turboexpanders

Learn how turboexpander magnetic bearing retrofits can boost production, extend equipment life and reduce vibration in a case study co-authored by L.A. Turbine and Waukesha Magnetic Bearings. Redesign options for the active magnetic bearing (AMB) system include a controller upgrade that maintains the original hardware and sensors or perform an upgrade of the controller and the AMB components. Both approaches are tested and proven to positively impact performance and robustness of the AMB turboexpander being used for hydrocarbon processing.
