The StirLNG-4 is our SPC-4 Cryogenerator specifically modified for micro scale LNG re-liquefaction in maritime conditions. Depending on the gas pressure, the StirLNG-4 can re-liquefy around 1000-1800 kg/day of LNG (1,8 metric tpd, 1350 gal/day) per single unit (multiple units possible).
Specifications
The Stirling Cryogenerator operates stand-alone, driven by an electrical motor and has its own control unit. Boil-off gas can be taken from a storage tank, re-liquefied by the StirLNG cooler, and pushed back into the storage tank.
Methane feed gas specifications to the StirLNG-4:
- Main stream CH4
- CxHy (C2 to C4) < 10%
- CxHy (C5+) < 1 ppm
- CO2 depending LNG conditions
- H2O < -70ºC dew point
- H2S < 3,3 ppm
- Oil content < 0,01 mg/m3
- Particles < 0,1 micron
- N2/O2 < 10%
The StirLNG-4 Maritime is Type Approved by ABS. Other notified body's upon request.
