METHOD FOR PRODUCING GAS HYDRATE

摘要

PROBLEM TO BE SOLVED: To realize stable operation of a dehydrator and realize operation in a definite dehydration ratio by preventing clogging of a draining part caused by a gas hydrate. SOLUTION: The method for producing the gas hydrate comprises reacting a raw material gas (g) such as natural gas with water (w) to produce a gas hydrate (n), mixing the gas hydrate (n) with water (w) to form gas hydrate slurry (s) and draining the slurry (s) by a dehydrator 12 to produce the gas hydrate having low water content. In the method for producing the gas hydrate, the draining part 19 is washed by vertically moving a liquid level in the dehydrator 12. COPYRIGHT: (C)2006,JPO&NCIPI
