AGA Gas, an industrial and specialty gas supplier and Swedish subsidiary of The Linde Group, has relocated its entire compressor and auxiliary equipment in an extensive transfer project.

Its oxygen (O2) Labyrinth Piston Compressor (Laby®), which had been in operation at its Stenungsund site for 35 years, no longer met the needs required by the customer and became redundant. As a result, AGA moved the equipment to a site in Sandviken 500kms away where it was needed to help revive an old air separation plant.

Burckhardt Compression, original equipment manufacturer (OEM) of the Laby Compressor, was selected to help facilitate the transfer due to its “excellent reputation for precision and quality,” said AGA Gas Project Leader Martin Welin-Berger.

The comprehensive relocation project involved moving the Laby Compressor and all its auxiliaries including cooling system, dampeners, oil system, supports and piping system. All parts were entirely dismantled, labelled and prepared for shipping and re-installation at the new plant in Sandviken.

The new location is planned to produce 30% lower volumes with reduced pressure of 36 bar instead of 50 bar. A high level of energy efficiency was achieved by installing a new motor.

The Laby Compressor features a unique labyrinth sealing system on piston and rod gland, which enables oil-free and contact-free compression and results in an extended mean time. Reinstalling the equipment at its new location also enabled Burckhardt Compression to revamp the Laby Compressor and apply the latest technology.

Mats Mjörnling, Plant Manager for AGA Gas in Sandviken, said he was “very satisfied” with Burckhardt Compression’s reciprocating field service engineers and added, “Frictionless collaboration and their comprehensive extensive know-how made everyone happy and I’m looking forward to working with them again for future maintenance service.”
