GE LDPE Hypercompressors API618 Brochure

GE Oil & Gas

Process Compressor

Designed for API 618 heavy-duty processing
applications, these units meet the broadest
and most stringent requirements.

Design philosophy

The latest generation of GE Oil & Gas process compressors is the
culmination of more than 40 years of research and development,
continually advancing design tools, field-proven installations and
global on-site experience.

Our modular approach to design and manufacturing takes advantage
of standardized core components that allow full customization to each
plant’s requirements – always with the highest reliability and availability.

Key features & benefits

• Standardized components ensure proven performance and
reliability, while increasing manufacturing and installation efficiency

• Extensive use of hydraulic tensioning to enhance reliability and
maintenance ease

• Broad cylinder line-up with bore up to 1,250 mm and materials to
accommodate all process requirements

• Proprietary cylinder valve design with plastic or metal plates to
minimize power losses and ensure longest life in operation

• Eccentric piston shoe grooves to extend shoe and packing seal life

• A wide range of construction materials available to suit specific

applications

• Extensive experience with every conceivable driver in a wide
range of applications such as gas and steam turbines, variable
and fixed-speed electric motors, and gas engines, with a unique
in-house capability to design and supply complete trains

• Unique in-house capability for piping pulsation and vibration
analysis to ensure smooth operation and extend the lifecycle of the
most highly stressed parts such as packing cups and cylinder valves

• Complete LDPE plant analysis capability (pressures up to
3,500 bar), including the primary-booster compressor, hyper
compressor, reactor, vessels and all interconnecting piping
