摘要： PROBLEM TO BE SOLVED: To provide a purification process for a gas hydrate capable of getting the gas hydrate with a high purity by purifying a slurry containing the gas hydrate made of water or sea water and a natural gas by a simple apparatus. SOLUTION: By pressurizing the slurry 6 containing the gas hydrate formed of water and a natural gas 8 in a high pressure vessel 2 whose internal temperature is 0-10°C at a pressure P 1 of 5-30 MPa by a piston 3 while blowing the natural gas 8 from the outside, a coexistence state of a crystal 18 and water is formed by growing the crystal 18 of the gas hydrate. The crystal 18 is pressed by holding the pressure P 1 while continuing the blowing of the natural gas 8 to squeeze up water remained in the crystal 18. After discharging the water remained in the high pressure vessel 2 outside, the inside temperature of the high pressure vessel 2 is lowered to -47°C to -5°C to stabilize the crystal 18.

摘要： PROBLEM TO BE SOLVED: To provide a gas hydrate wash-column that washes unreacted seawater accompanying hydrate with a required minimum of washing water and smoothly draining the seawater without obstructing washing. SOLUTION: The gas hydrate wash-column 4 comprises a hydrate slurry introduction part 22, a draining part 23 for dehydrating unreacted seawater in a hydrate slurry and a washing and scraping part 24 for diluting unreacted seawater attached to hydrate and scraping the hydrate after washing to the outside of the system. The washing and scraping part 24 is equipped with a rotary or wiper type gas hydrate scraping apparatus and a washing water spray nozzle. When the void percentage of a hydrate in a saturation area E is ε, the cross-sectional area of the wash-column is A, the rise rate of a hydrate sedimentary layer is U and the saturation degree of a hydrate in an unsaturation area F is S, the water amount Q of washing water sprayed from a washing water spray nozzle satisfies formula (1): Q=1.1ε×A×U×S.
