Development of the ZR-LNG Process for Mid-scale liquefaction and monetization of stranded gas reserves
Lead Participant:
GASCONSULT LIMITED
Abstract
GASCONSULT LIMITED has developed and patented a new natural gas liquefaction technology, Zero Refrigerant
LNG (ZR-LNG). The technology is highly differentiated; unlike competing processes it uses no external
refrigerants, relying on use of the natural gas feed in an optimised system of expanders to effect refrigeration.
This eliminates certain process equipment reducing cost and footprint. Make-up refrigerant is low cost natural
gas as opposed to imported nitrogen or a cocktail of liquid hydrocarbons making the process particularly suited
to remote locations and less developed economies. The ZR-LNG system is highly efficient, almost equal to
sophisticated base load dual refrigerant processes and fully 30% better than the dual nitrogen expander
process. These unique features offer the potential to monetize otherwise stranded natural gas. Innovate UK has
awarded Gasconsult a grant to permit engineering development of the ZR-LNG concept for a coal bed methane
prospect in Botswana. Thereafter it can be considered for the many new LNG projects expected to be
developed world-wide in the coming decades.
