TURBO-EXPANDERS Modern turbo-expanders can achieve almost isentropic expansion resulting in much lower temperature drops than possible with a valve. The Extracted Energy is used to drive another rotating machine such as compressor, generator or pump. CRYOSTAR have manufactured thousands of turbo-expanders since the early 70s. Our machine range includes turbo-expander/compressor, turbo-expander/generator and turbo-expander/ Oil-Brake. All our hydrocarbon turbo-expanders are built in accordance with API 617 of which CRYOSTAR is an active member. Our expanders are radial inflow turbo-machines...

HYDROCARBON TURBO-EXPANDERS VARIABLE INLET GUIDE VANES (IGVs) Our variable IGVs maintain optimal efficiency on a large operating range while allowing smooth regulation of your process. Typically, IGVs allow an operating range between 30% and120% of the nominal mass flow. WHEELS CRYOSTAR specifically designs each wheel to maximize efficiency. Depending on your needs, open or closed wheels can be proposed in various materials, Aluminium, Titanium or Stainless Steel ranging from 70 mm (2 ¾ inches) to 900 mm (35 ½ inches) with peak isentropic efficiency up to 92%. SHAFT SEALS Depending on...

TURBO-EXPANDER/COMPRESSORS The turbo-expander/compressor is a single shaft machine where the compressor is directly driven by the expander. The rotor can be supported either by Oil Lubricated Bearings (OLB), CRYOSTAR's TC model, or Active Magnetic Bearings (AMB), CRYOSTAR's MTC model. COMPRESSOR DESIGN It consists in a single stage centrifugal type compressor. It is designed in accordance with API 617. COMPRESSOR DIFFUSOR To optimize compressor range and performance, CRYOSTAR can propose a variety of fixed or variable diffusors: ★ Vaned to maximize compressor head. ★ Vaneless to maximize...

HYDROCARBON TURBO-EXPANDERS OIL LUBRICATED BEARINGS TURBO-EXPANDER/ COMPRESSOR (MODEL TC) CRYOSTAR manufactures Oil Lubricated Bearings Turbo-expander/compressors since 1974 and has delivered thousands of them ever since. ROTOR Machined from Solid forging, low thermal expansion BEARINGS Combined axial (tapered land) / radial bearings (tilting pads): High capacity on a large operating range LUBE OIL SYSTEM It can be designed in accordance with API 614 General or Special Purpose. Since most OLB Turbo-expander/compressors use labyrinth seals, lube oil reservoir is usually connected to...

ACTIVE MAGNETIC BEARINGS TURBO-EXPANDER/COMPRESSOR (MODEL MTC) CRYOSTAR was the first company to develop the hydrocarbon expander/compressor with Active Magnetic Bearings in the 90s. Thanks to their unmatched reliability, these machines are a well proven design and have become a standard. 1988 - World first AMB Expander/Compressor | Air Separation Unit (Motherwell, UK,British Oxygen Company) 1990 - First AMB Expander/Compressors (4 units) | Natural Gas Processing (Sleipner A Platform, Norway, Statoil) 1991 - AMB Expander/Compressor | Olefin Plant (Notre-Dame de Gravenchon, France,...

HYDROCARBON TURBO-EXPANDERS AUXILIARY LANDING BEARINGS They are used as ultimate back-up and consist in ceramic ball bearings. In the unlikely event of loss of levitation, they will allow the rotor to stop while protecting the system from damage. AMB CARTRIDGE Equipped with Radial and Axial bearings and instrumentation (displacement, speed, temperature) Material compatibility with upstream natural gas: « « Mercury compatible « « NACE region 0 or 1 as option ©SKF ROTOR The shaft is fitted with ferromagnetic lamination (stacked ring layers) to ensure optimal magnetic induction whilst limiting...
