Description

KRAV 1. Fremgangsmåde til transport af en strømning af fluidformige carbonhydrider, der indeholder vand, gennem et behandlings- og transportsystem, der indbefatter en rørledning, hvilken fremgangsmåde er kendetegnet ved, at strømningen af fluidformige carbonhydrider føres ind i en reaktor, hvor den blandes med partikler af gasformige hydrater, der også føres ind i reaktoren, idet udløbsstrømningen af carbonhydrider fra reaktoren afkøles i en varmeveksler for at sikre, at alt vand, der er til stede deri, er i form af gasformige hydrater, idet strømningen derefter behandles i en separator for at blive separeret i en første strømning og en anden strømning, hvor den første strømning, der har et indhold af gasformigt hydrat, recirkuleres til reaktoren til tilvejebringelse af de ovenfor nævnte partikler af gasformige hydrater, og hvor den anden strømning overføres til en rørledning for at blive transporteret til sit bestemmelsessted. 2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at strømningen af fluidformige carbonhydrider afkøles i en første varmeveksler, inden den føres ind i reaktoren. 3. Fremgangsmåde ifølge et hvilket som helst af kravene 1 og 2, kendetegnet ved, at ønskede kemikalier tilsættes opstrøms for reaktoren. 4. Fremgangsmåde ifølge et hvilket som helst af kravene 1-3, kendetegnet ved, at strømningen af fluidformige carbonhydrider underkastes en blandingsoperation, inden den føres ind i reaktoren, for at dispergere det vand, der er til stede som små dråber i den fluidformige carbonhydridfase. 5. Fremgangsmåde ifølge et hvilket som helst af kravene 1-4, kendetegnet ved, at den anden strømning fra separatoren blandes med våd gas, inden den overføres til rørledningen. 6. Fremgangsmåde ifølge et hvilket som helst af kravene 1-5, kendetegnet ved, at fremgangsmåden udføres på havbunden. 7. Fremgangsmåde ifølge et hvilket som helst af kravene 1-6, kendetegnet ved, at der anvendes et ikke-isoleret rør som varmeveksler, når omgivelsestemperaturen er tilstrækkelig lavt. 8. Fremgangsmåde ifølge et hvilket som helst af kravene 1-7, kendetegnet ved, at de flu-idformige carbonhydrider er carbonhydridgas. 9. Fremgangsmåde ifølge et hvilket som helst af kravene 1-8, kendetegnet ved, at carbon-; hydridstrømningen føres gennem en reduktionsventil, der er anbragt opstrøms for reaktoren eller er en del af reaktoren. 10. Fremgangsmåde ifølge et hvilket som helst af kravene 1-9, kendetegnet ved, at strømningen fra reaktoren føres gennem en første separator for at blive separeret i en carbonhy-dridgasstrømning og en strømning, der efterfølgende underkastes separation i en anden separator til nævnte første og anden strømning. 11. Fremgangsmåde ifølge krav 10, kendetegnet ved, at afkølet kondensat under tryk tilsættes til den første strømning, som recirkuleres til reaktoren. 12. System til behandling og transport afen strømning af fluidformige carbonhydrider, der indeholder vand, hvilket system er kendetegnet ved, at det indbefatter følgende elementer, der er angivet i strømningsretningen og forbundet med hinanden: forbindelse til en carbonhydridkilde (1), en første varmeveksler (4), en reaktor (6), en anden varmeveksler (7), en separator (8), og en rørledning (13); og desuden en ledning (9), der fører fra separatoren (8) til reaktoren (6) og er forsynet med en pumpe (10), som er indrettet til at recirkulere materiale fra separatoren (8) tilbage til reaktoren (6). 13. System ifølge krav 12, kendetegnet ved, at indersiden af reaktoren (6) er belagt med et vandskyende materiale. 14. System ifølge et hvilket som helst af kravene 12 og 13, kendetegnet ved, at det indbefatter en blander (5) mellem den første varmeveksler (4) og reaktoren (6). 15. System ifølge et hvilket som helst af kravene 12-14, kendetegnet ved, at det indbefatter organ (2) til tilsætning af kemikalier til strømningen. 16. System ifølge et hvilket som helst af kravene 12-15, kendetegnet ved, at det indbefatter organ (12) mellem separatoren og rørledningen til blanding afstrømningen fra separatoren (8) med våd gas (11), inden strømningen ledes ind i rørledningen (13). 17. System ifølge et hvilket som helst af kravene 12-16, kendetegnet ved, at det indbefatter en separator (14) mellem den anden varmeveksler (7) og separatoren (8) til genvinding af carbonhydridgas fra strømningen. 18. System ifølge et hvilket som helst af kravene 12-17, kendetegnet ved, at det omfatter organ (16) til tilsætning af afkølet kondensat under tryk til ledningen (9) fra separatoren (8) til reaktoren.
