APPARATUS FOR PRODUCING HYDRATE

摘要

PROBLEM TO BE SOLVED: To produce hydrate having large particle diameter in a hydrate-producing apparatus. SOLUTION: In the hydrate-producing apparatus 10, an unreacted natural gas NG in a spray tower 12 is cooled and circulated by a gas circulation line 42. A gas feed line 36 is branched and the natural gas NG is fed to the spray tower in a state divided from the bottom of the spray tower 12 to the upper part of the tower 12. The natural gas NG forms stream which flows from the bottom to the upper part in the spray tower 12 and residence time of water W is prolonged by keeping whole height of a hydrate production area A of the spray tower 12 to≥10 m.
