Oil & Gas

Turboexpanders are used in many production and processing activities in the oil and gas industry from the extraction of hydrocarbon liquids from natural gas to energy recovery in petrochemical and gas pipeline pressure letdown.

Calnetix turboexpander systems run on magnetic bearings and are hermetically sealed in a single housing, eliminating the need for a gearbox, lubrication system or any auxiliaries. The in-line connection into existing piping systems provides little to no impact on footprint.

Turboexpander systems with Calnetix’s Magnaforce™ motor generators are enabling newer applications in oil and gas, such as the energy recovery from natural gas pressure letdown.  These natural gas turboexpanders extract energy from the pressure reduction required at various stages of gas distribution.  This allows for the generation of additional electricity with no added pollution or energy input.
