Method and apparatus for generating, transporting and dissociating gas hydrates
Patent 5473904 Issued on December 12, 1995. Estimated Expiration Date: November 12, 2013. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
Methods and apparatus for generating, transporting and dissociating gas hydrates are disclosed. The preferred apparatus includes a mobile tank initially containing liquid water. Compressed hydrate-forming gas is combined in a pipe with the liquid water under locally supercooled conditions. The formed gas hydrate is blown into the mobile tank for transport and eventual consumption.
