Description
PATENTKRAV 1. Fremgangsmåde til udvinding af methanhydrat på havbunden, kendetegnet ved, at et ved begge ender åbent transportrør føres ind i området med methanhydrat, at der ved det nedre område af transportrøret indføres højtryksluft, og at der i den derved i røret nedefra og opad frembragte stærke strømning medrives fast methanhydrat, hvoraf størstedelen optøs inden i transportrøret, og den derved forekommende gasfraktion opfanges i det øvre område af transportrøret. 2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der ved det nedre område af transportrøret indpumpes eller indpresses en tung uren væske sammen med trykluften eller alene, hvorved der på grund af de forskellige densiteter af den tunge urene væske frembringes en opdriftsstrømning i transportrøret og medføres methanhydratmasser i strømningen . 3. Fremgangsmåde ifølge et af kravene 1 eller 2, kendetegnet ved, at tværsnittet af transportrøret bliver kontinuerligt bredere nedefra og opad. 4. Fremgangsmåde ifølge krav 2, kendetegnet ved, at den opadstrømmende tunge urene væske adskilles fra vandet og på ny tilføres kredsløbet i det nedre område af transportrøret. 5. Fremgangsmåde ifølge et af kravene 1 til 4, kendetegnet ved, at trykluften og/eller den 1 tunge urene væske forvarmes. 6. Fremgangsmåde ifølge et af kravene 1 til 5, kendetegnet ved, at de med henblik på udvinding af methanhydratet anvendte rør varmeiso-leres.
