Liquid Gas Transport and StorageReciprocating Compressors for Low Temperature Gases Down to Minus 170 °C
2
Burckhardt Compression, in business for well
over a century, is one of the world’s largest
manufacturers of reciprocating compressors.
The company is the only manufacturer of a
complete series of labyrinth piston (Laby®),
process gas and hyper compressors for numer-
ous applications. Detailed knowledge of the
dynamic processes in compressors as well as
Your Partner – Burckhardt Compression
Your Industry – Gas Transport and Storage
close-to-reality simulations of compressors in
operation enable Burckhardt Compression to
customize compressors and optimize their
performance for a given application. The
compressors are manufactured in Burckhardt
Compression’s Winterthur plant (Switzerland)
in accordance with ISO 9001:2000 standards.
Burckhardt Compression – the world’s most experienced supplier of compressors for low temperature gases
Burckhardt Compression, your preferred
supplier of compressors for:
Olefins and other petrochemicals• Cryogenic storage, boil-off gas recovery and
send-out of ethylene and propylene
• Re-condensation of LPG boil-off gases
(BOG) produced during transport and
storage in land receiving terminals
RefrigerationCompressors for closed loop cascade

Oil and gas, power generation industry,LNG terminalsRecovery and handling of very low tempera-
ture gases produced during transport, ship
unloading and tank pressure holding duty.
Compressors for suction temperatures down
to minus 170 °C.
• LNG boil-off gas is normally re-condensed by
absorption into pumped LNG send-out liquid
• A few terminals compress the boil-off gas
directly up to pipeline pressure
• Import terminals are characterized by a very
wide range of boil-off gas flows:
- Large volumes of gas produced during ship
unloading
- Small flows during tank pressure holding
duties
- Compressor control range from 100 % to
25 % or lower

Technological solutions for highreliability• Materials carefully selected according to
operating temperatures, providing optimum
component lifetime of wearing parts
• Minimum number of wear and tear parts due
to unique labyrinth sealing
- No PTFE piston and rider rings
- Simple packing design for little wear
in operation
• Gas-tight hermetically sealed crankcase
design
• Extensive use of coolant for maximum
efficiency and reliability
Operational benefits• Excellent reliability and availability at very
low temperatures
• Highly flexible operation over wide operating
temperature range from plus 40 to minus
170 °C, including nitrogen commissioning
• No special cool-down procedures required
• Efficient multi-step turndown operation by
combination of well-proven valve unloaders,
stage bypass and clearance pockets if required
• Highly cost efficient operation due to gas
tight casing design:
- Zero packing leakage; zero gas loss to vent
or flare
- No utility purge gas required for the
distance piece during operation
Project planning and execution• Low installation space requirements due to
vertical compressor design
• Easy maintenance access to critical compo-
nents, like compressor valves
