Hyper Compressors

The Hyper compressor is a high-pressure reciprocating compressor for low density polyethylene plants, with discharge pressure up to 3500 bar (50'000 psi). Burckhardt Compression has an outstanding experience of over 55 years in manufacturing Hyper compressors. It excels with long lifetime and high safety requirements thanks to its unique design features and Burckhardt Compression's worldwide one-stop service.
 
The world's most powerful compressor, driven by a 27'500 kW (36'900 HP) electric motor and compressing 160 tons of ethylene per hour to a discharge pressure up to 3100 bar (45'000 psi), was built by Burckhardt Compression in 2007.

Design features

• Rugged motion work with low specific loads for long operating life
• Simple and robust design
• Auxiliary crosshead for enhanced guidance of high pressure plungers, thus prolonged packing life and safe operation
• Easy access to all wear parts
• Distance piece between motion work and cylinder, preventing gas from entering crankcase with a safety device to prevent crankcase damage
• Three different frame sizes available to minimize number of cylinders in operation
• Lube oil held in separate tank for safe operation
• High availability of compressor (crucial for continuous process operation) thanks to large cylinder bolts, slower rotation speed and an additional crosshead that reduces plunger stress
• Quick replacement of cartridge-type cylinder inserts
• Minimized motion parts such as a unique central valve 

• Ethylene
• Ethylene vinyl acetate
• Co-monomers
