Abstract
Disclosed are a device and a method for manufacturing a natural gas hydrate. Provided is the device for manufacturing a natural gas hydrate comprising: an ice slurry generation unit for preparing ice slurry having 13-20% of ice at normal pressure; a first pipe, having one end connected to the ice slurry generation unit for withdrawing the ice slurry from the ice slurry generation unit, and in which a high-pressure pump for increasing pressure on the ice slurry is interposed; a hydrate preparation reactor, which is connected to the other end of the first pipe so as to receive the pressurized ice slurry, and to which natural gas is supplied and mixed, for generating natural gas hydrate slurry; a second pipe, having one end connected to the hydrate preparation reactor, for withdrawing the natural gas hydrate slurry; and a dehydrating portion, which is connected to the other end of the second pipe, for dehydrating the natural gas hydrate slurry.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
