METHOD AND SYSTEM FOR PRODUCING GAS HYDRATE

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing high purity gas hydrate by arranging the most suitable production step corresponding to the ratio of unreacted water in the production of the gas hydrate, and to provide a system therefor. SOLUTION: The method for producing gas hydrate comprises reacting a raw material gas g with water w to produce gas hydrate of the gas with water. The method comprises (a) a first production step for producing a low purity gas hydrate slurry s by dispersing the raw material gas g in water or by mixing with water w, (b) a dehydration step for removing unreacted water by filtrating the low purity gas hydrate slurry flowing in from the first production step and (c) a second production step for producing high purity gas hydrate by re-reacting the gas hydrate dehydrated in the dehydration step with the raw material gas and/or the remaining water and raw material gas g adhered on the gas hydrate, while agitating and mixing with a mechanical agitating means.
