capable of handling a range of field gas compositions

Costain initially carried out consultancy work to identify the most appropriate processing solution for liquefaction. The process selected uses the proven nitrogen expander liquefaction cycle, one of the most robust and flexible offshore LNG technologies. The design included the following:

  • Plate fin heat exchangers
  • Cold boxes
  • Cryogenic pumps
  • Liquid expanders
  • Turbo-expanders

Costain was awarded the contract to continue providing engineering services through to detailed design and package management, bringing extensive cryogenic experience in gas processing and LNG to the project.
