Polyolefins production

With our extensive experience in polyolefin applications, we provide the ideal compression solutions for your polyethylene (PE) or polypropylene (PP) projects. Our solutions are highly recommended by various process licensors for their reliability and proven track record.

Sustainable compression solution

• Gas tight with no leakage to ambient / flare.
• Buffer gas compatible with the process is fully recovered.

Cost saving operation

• Increased uptime due to contactless sealing technology on the piston skirt and the piston rod, preventing hot spots risking unwanted polymerization.
• Proven longest Mean Time Between Failures (MTBF) in reciprocating compresser technology.
• Short Mean Time to Repair (MTTR) enabled by friction-free Laby® compression which is insensitive to catalyst particles (i.e. TEAl).
• Lowest OPEX during entire lifetime.
• Minimized service and spare part costs.

Gas tight to ambient / flare

• Pressure tight crank gear and distance piece (from 2 to 25 barg).
• Leakgas recovered to compressor suction.
• Buffering system

Oil free gas compression

• Metallic precise Laby piston skirt without cylinder liner.
• Laby piston rod gland sealing
• From distance piece on oil free, due to installed oil scrapers.

Compatible material selection for the process

• In house valve engineering and manufacturing, to ensure highest quality standard and long reliable operation.
• No copper alloys in the process area.

• Customized solutions to handle mixed gas compositions with nitrogen (N₂)
• Awailable for various heavy hydrocarbons at different suction pressure levels
  • Ethylene C₂H₄
  • Propene C₃H₆
  • Butadiene C₄H₈
  • Hexane C₆H₁₄
