An efficient and simple process !

The process is based on biomethane liquefaction and storage under liquid form and regaseification upon injection. A unit is made of several modules :

GRID polishing module (only for grid gas processing) : proprietary system in order to process water, CO₂ and tetrahydrothiophene (THT – gas odorant for natural gas)
Polishing module required for liquefaction : proprietary and patented system in order to remove CO₂ remaining in
Liquefaction module : proprietary open cycle liquefaction system running without rotating machinery
(Bio)LNG storage module :LNG storage system at -160 degrees. LNG storage ranging from 10 to 100 m³ (6 000 à 60 000 Nm³ under gaseous form)
Reinjection module : (Bio)LNG regasification system
Control module : integrated start/stop automatic system (starting in less than an hour) coupled with remote control/alarm

Key benefits

of our solution

from 50 to 500 Nm³/h

our unit starts and stop automatically. It adapts to congestion level and doesn’t required additional compression.

high reliability also due to the absence of rotating machinery.

flow rate performances range from 30% to 100%

unit start and stop in less than one hour

due to the absence of compressors or cold machinery, a unit’s capacity is less than 2,5kWe.
