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.
