1. Metoda za ukapljivanje plinovitog metana, u kojoj:
- osiguran je izvor plinovitog metana koji proizvodi protok plinovitog metana 5 na temperaturi T1 i tlaku P1,
- osiguran je izvor tekućeg dušika koji proizvodi protok tekućeg dušika pri tlaku P2 i pri temperaturi T2 koja je niža od temperature trojne točke metana,
- u prvom izmjenjivaču, protok plinovitog metana 10 na temperaturi T1 hladi se, kao protustruja, na temperaturu T3 koja odgovara onoj njegove točke rosišta izmjenom topline s protokom plinovitog dušika na temperaturi T4 iz bubnja za razdvajanje faza,
- protok plinovitog metana na temperaturi T3 prenosi se u drugi protustrujni izmjenjivač,
- protok tekućeg dušika na temperaturi T2 prenosi se iz izvora tekućeg dušika u bubanj separatora faza,
- temperatura T4 koja je viša od temperature trojne točke metana i tlak P4 primjenjuju se u bubnju za odvajanje faza na takav način da su tekuća faza na temperaturi T4 koja stvara protok tekućeg dušika i parna faza na temperaturi T4 koja stvara protok plinovitog dušika prisutne unutar navedenog bubnja,
- u drugom izmjenjivaču, protok plinovitog metana na temperaturi T3 se ukapljuje, čime se proizvodi protok tekućeg metana na temperaturi T5 isparavanjem protoka tekućeg dušika na temperaturi T4, čime se proizvodi protok isparenog dušika na temperaturi T4,
- protok isparenog dušika na temperaturi T4 prenosi se u bubanj separatora,
- protok tekućeg metana na temperaturi T5 prenosi se i zatim skladišti u spremniku koji sadrži fazu tekućeg metana i fazu plinovitog metana; navedena faza plinovitog metana izlazi iz navedenog skladišnog spremnika, čime se formira tok istjecanja metana, naznačen time što
- protok istjecanja metana na temperaturi T5 usmjerava se u prvi izmjenjivač kao protustruja protoku plinovitog metana na temperaturi T1, te kao istostruja s protokom plinovitog dušika na temperaturi T4, čime se doprinosi hlađenju navedenog strujanja plinovitog metana.
2. Metoda prema zahtjevu 1, naznačena time što se temperatura T4 održava unutar bubnja za odvajanje faza reguliranjem tlaka P4 unutar navedenog bubnja.
