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
