Burckhardt Compression will be delivering its Laby® compressor system for largest monoethylene glycol plant in the US.

The new plant will be located in Lake Charles, Louisiana and is part of a larger project primarily comprising the construction of an ethane cracker facility. Monoethylene glycol is a key ingredient for various important industrial and consumer goods, such as textile fibers, paper, asphalt, PET bottles, adhesives and antifreeze. With an annual capacity of 700,000 tonnes, it will become the largest plant of its kind in the US.

The multi-stage Laby labyrinth piston compressor designed and engineered by Burckhardt guarantees the continuous compression and delivery of 8,050 kg/h of process gas at a pressure of 2.09 MPa (abs). It will be delivered as a complete reclaim compressor system including an electric motor drive, skid-mounted oil system and skid-mounted water console with a standalone air-cooled heat exchanger.

Burckhardt’s reliable Laby compressor has a unique labyrinth sealing system on its piston and piston rod gland, which enables oil-free and contact-free compression. The result is an extended mean time between overhaul (MTBO), which has a positive impact on reliability and operating costs. The Laby compressor is designed to compress bone-dry, dirty, abrasive and other gases. The gastight casing reduces gas emissions and losses to the environment to virtually zero.

The MEG plant is planned to become operational in 2019.
