CRYOSTAR is a manufacturer
of expansion turbines
for hydrocarbon and
air gas industries. As a world
class manufacturer CRYO-
STAR is the preferred supplier
of turbines for hydrocarbon
gas processing for many
engineering companies and
end users for the Oil & Gas
industry. This was confirmed
by the recent supply of 8 large
turboexpanders to Linde and
12 HC turboexpanders for
other customers which are to
be delivered in the year 2003.
The CRYOSTAR hydrocarbon
expansion turbines are very
robust, reliable and highly
efficient machines built to latest
API 617 Standards. The achieved
isentropic efficiency level of up
to 92% is outstanding in the
industry and it documents the
30 years experience gained in
aerodymanic wheel and nozzles
design. The turboexpanders are
utilized for cryogenic gas processing,
i.g. for: natural gas plants
Spring 2003
for NGL recovery, olefin plants,
LNG production, pipeline gas
dew point control and H2/CO
processing.
Lube oil and seal gas
systems
To fulfil the Oil & Gas industry
requirements the CRYOSTAR
lube oil and seal gas systems
follows the API 614 and API 617
Standards. Pressurized, drainer
and atmospheric lube oil systems
are utilized for hydrocarbon turbines
and are built completely in
stainless steel execution, to cope
with the harsh environmental
conditions in refineries.
Engineering and
Technology
Full in house engineering
capability and expertise enable
fast reaction to the market and
customers requirements. State of
the art design, manufacturing
and testing tools are utilized:
CAD/CAM, FEA, CFD, aerodynamic,
rotordynamic and
stress analysis computer tools,
PDM, outsourcing & supply
management, automated data
acquisition, ADRE vibration
analysis, etc.
The Pioneer technology role of
CRYOSTAR in turboexpander
industry is underscored by:
> High pressure (185 bars)
turboexpander for natural
gas processing with API 614
pressurized lube oil system
built in 1976
> First turboexpander worldwide
with magnetic bear
ings for air separation industry
- prototype built in 1982
> First turboexpander with
magnetic bearings for natural
gas processing ordered in
1989
Testing
During the last decade CRYOSTAR
invested more than 3 Mio € in
modern and state of the art
turbine test facility and data
acquisition system with on line
performance visualization. The
testing of HC turbines follows the
recognized ASME PTC 10 Code.
