Cryostar
Cryostar is a leading supplier of cryogenic equipment for
industrial and natural gas applications, including cryogenic
pumps, turboexpanders, small scale liquefaction plants, LNG
boil-off gas (BOG) compressors and LNG vaporisers.
Cryostar’s multistage cryogenic vertical process (VP)
pump is designed for continuous operations with all
liquefied air gases, dedicated to air separation unit
applications. The pump is generally used for internal
compression, recycling, send out, back-up (O
2
/N
2
/Ar) and
in methane wash or LNG applications. Kept in permanent
cold stand-by, the pump is ready for an immediate start.
With various sizes of VP pumps (from 115 to 330 mm) and
the modular multi-stage design, the range of flow rates is
extended from 25 to 5000 l/min (1350 gpm), up to 130 bar
(1900 psig). The VP pumps are equipped with a standard
choice of sealing systems, interchangeable according to
the process: two or three chambers labyrinth or dry gas
seal. Reliable and safe, the VP pump is supplied with a rigid
and insulating flange to mount on the cold box. The pump
is submitted to stringent performance tests in cryogenic
conditions, in the world’s largest liquid nitrogen test
facility.
With more than 50+ years’ experience in the cryogenic
pump business and more than 5500 process pumps
installed, Cryostar is a customer-focused organisation, with
the support of nine business centres worldwide, and a
network of agents and distributors.
Cryostar also offers long-term equipment follow-up,
including supervision, on site intervention with skilled
technicians, on-site or in-house repair services, spare parts,
and revamping.
C.S.T.
–
Compression Service Technology
S.r.l.
C.S.T., founded in Florence, Italy, in 2002, was initially
composed of just four people and worked as a service
engineering provider for an Italian original equipment
manufacturer (OEM), mainly for reciprocating compressors.
In 2004, the company began to set up a remote
monitoring and diagnostic service for reciprocating
compressors. It started with the design of machine
components and packages for reciprocating compressors and
later moved onto centrifugal compressors. In the meantime,
the company has developed its proprietary software for
performance simulation, as well as pressure pulsation,
vibration, and rotor-dynamic analyses.
The company recently produced its own line of precision
lubrication systems for cylinders and packings of reciprocating
compressors, called CST-PLS. The system, designed on the
basis of over 15 years of experience in reciprocating
compressors, has been successful since the first application.
In just 15 years, C.S.T. has transformed from a local
maintenance engineering provider for reciprocating
compressors into an international player for critical machine
applications in the oil and gas and other industrial sectors.
The company currently employs around 50 staff, and
while its business was initially almost 90% in Italy, in the next
year C.S.T. expects to reach 50% of its sales from foreign
markets.
The company is composed of four main divisions:
machine design, system engineering and construction, service
and remote diagnostics, and R&D. C.S.T. is able to offer
full-scope customer support, from design to project
execution and troubleshooting, remote monitoring and
Atlas Copco Gas and Process
Across the globe – from the US, the Middle East and China
– Atlas Copco Gas and Process has produced some of the
most reliable and available machines for the world’s most
demanding chemical-petrochemical applications.
The polyolefin process can be particularly complex and
rigid, and the company’s 50+ years of expertise in this
market has enabled the design of turbomachinery that
offers 99% availability, even in harsh environments.
Whether its customer’s application requires a
direct-driven or integrally-geared compressor solution, all of
Atlas Copco Gas and Process’ machines are engineered to
help support plant availability (e.g. by reducing
polymerisation risks in the compressor). To that end, critical
components such as impellers, casings, guide vanes shaft
seals, gears and bearings are anchored in proven,
field-tested designs that were specifically engineered to
reduce these risks.
In addition to engineering reliable and available
turbomachinery, Atlas Copco Gas and Process is always
mindful of the costs that affect customer decisions in each
purchase. In many scenarios, standardised machinery can be
used to lower CAPEX and shorten delivery times. All
machines – standardised and custom – feature unique
aerodynamics that match each process. The custom
aerodynamics coupled with Atlas Copco’s efficient designs
allow for OPEX savings once the machines are running.
Atlas Copco Gas and Process can design a robust,
reliable polypropylene /polyethylene compressor which
meet the standards of API 617, API 614, ERC (Russia),
CSA/CRN and others.
In addition, Atlas Copco Gas and Process helps
customers prepare for tomorrow by designing, building, and
servicing turbocompressors, gas screw compressors and
turboexpanders for the oil and gas, power generation and
industrial gases industries.
Atlas Copco Gas and Process is a division of the
Compressor Technique business area, headquartered in
Cologne, Germany, with additional production centres in
the US, China and India
