Going global with zero refrigerant modular LNG and small-scale iLNG

2/2/2018

(UK) In addition to patents already held, further patents have been awarded for the ZR-LNG process in South Korea and Australia, and Gasconsult is working on further patents for the USA, Canada, Malaysia and India.

Work is also proceeding well on their UK Government Innovate funded design work for nominal 1.4 million tonne/y and 1 million tonne/y FLNG modules. Gasconsult expect to complete the bulk of the technical work around end February 2018. The outcomes are presently very encouraging.

Independent third party evaluation by recognised process design experts confirm ZR-LNG as a very efficient process with power demand equal or better than SMR configurations and substantially reduced complexity relative to DMR schemes.

ZR-3D FLNG Model

Depending on location, fabricator capability or the need for procurement flexibility the 1.4 million tonne/y FLNG module can be built either as a single module or as two separate modules.

Their ZR-iLNG small-scale liquefaction initiative being developed jointly with Osomo Projects BV continues to progress. This is based on Gasconsult’s “zero-refrigerant” liquefaction technology and Osomo’s membrane and CO2 freeze-out processes. This development aims to increase the economic viability of small liquefaction schemes through elimination of equipment and through system simplification.

Specifically the equipment count is reduced as there is no refrigerant infrastructure cost with further reductions arising from elimination of the amine and dehydration systems.
