Document Type and Number:
Japanese Patent JP2008248032
Kind Code:
A
Abstract:

To provide a method for producing a gas hydrate having a high hydrate content in a short time and a device for the same.

This method for producing the natural gas hydrate comprises a first process of introducing a raw material gas G and raw material water W in a reaction vessel 2 holding a prescribed pressure and temperature and bringing the raw material gas in contact with the raw material water W for forming a first slurry S1 containing powdery natural gas hydrate, and a second process of forming a liquid surface WL presenting the natural gas hydrate on the surface of the first slurry S1, bringing the liquid surface WL in contact with the raw material gas G and forming the second slurry P2 increased with the particle diameter of the natural gas hydrate.
