This paper is a follow up to GT2022-82293, which discusses the design validation of an innovative turboexpander-generator (TEG) used for natural gas pressure letdown (PLD).

A 300 kW turboexpander-generator was developed by Baker Hughes, in conjunction with Calnetix Technologies, for use in a natural gas pressure letdown application.

This paper describes the design and development of an innovative 280 kW and a 125 kW Turboexpander Generator (TEG) for natural gas pressure letdown (PLD) applications.

Gas pipeline pressure letdown (PLD) stations are used to step down the pressure of gas at various stages of a gas transmission infrastructure. This paper focuses on two such gases: (1) natural gas and (2) hydrogen.

This paper is a follow-up to GT2021-60125 (“Design and Analysis”) and GT2021-60317 (“Economic Analysis”), which collectively covered the design, analysis, and economics of innovative Turboexpander Generators (TEG) used in pressure letdown (PLD) applications.

A low cost cryogenic expander system that incorporates a high performance, high-speed permanent magnet generator and low loss magnetic bearings is described.

A 300 kw integrated and fully-sealed turboexpander-generator for natural gas pressure letdown (pld) was developed by baker hughes, a ge company (bhge), in conjunction with calnetix technologies.

The development and testing of an integrated power module (IPM) for a waste heat recovery system is described. The IPM is part of a waste heat recovery system based on the organic Rankine cycle.

A magnetic bearing system for a high-speed cryogenic gas expander generator is presented. The expander represents a new class of such devices that, in contrast to the earlier technologies, makes use of the expanding gas energy by converting it into electrical power.

A cryogenic gas expander system that incorporates a high-performance, high-speed permanent magnet, direct-drive generator and low loss magnetic bearings is described.

Interview with Freddie Sarhan on the Innovating with Scott Amyx Podcast discussing Sapphire's Turboexpander technology and how it fits into the energy infrastructure.

In this week’s episode of the Pipeliners Podcast, host Russel Treat is joined by Jeff Earl of Sapphire Technologies to discuss using turbo expanders to convert waste pressure energy into usable electric power.

Welcome to Sapphire Technologies, where we proudly showcase our groundbreaking clean technology and the remarkable individuals who are dedicated to protecting and preserving the environment. Together, we can create a world where technology and environmental consciousness go hand in hand.

Explore how turboexpander-generators (TEGs) create clean electricity by recovering unused energy in pressure letdown processes. A focus will be placed on how novel technologies can be integrated into TEGs to differentiate them from traditional rotating equipment offerings.

Sapphire and Evolve partnership creates a solution that can recover power throughout a midstream sector, which research shows is currently wasting up to 2,900 megawatts of pressure energy.

Hydrogen and natural gas are pressurized to facilitate efficient transportation in pipelines across long distances.

Hydrogen is a rapidly expanding global energy storage market. Hydrogen is used in many manufacturing processes from petroleum refining to food processing.

Sapphire Technologies designs, develops and manufactures highly engineered FreeSpin® In-line Turboexpanders (FIT) for natural gas processing and distribution systems.
