- the heat generated when a phase of water and natural gas at 0 degrees Celsius is converted to natural gas hydrate is about 433 kJ / kg and the latent heat of melting of ice is about 335 kJ / kg. Therefore, the latent heat of ice is used to remove the heat of natural gas hydrate.
- the ice slurry of 13% to 20% of the ice fraction may produce a natural gas hydrate slurry of 10% to 15% of the natural gas hydrate fraction in an adiabatic state.
- the natural gas hydrate manufacturing apparatus can continuously generate natural gas hydrates by using latent heat of an ice slurry having an ice fraction capable of securing fluidity.
- the term "continuously producing” means that the natural gas hydrate can be produced continuously without producing a natural gas hydrate in a batch form in one operation of the manufacturing apparatus. Therefore, the flowability of the ice slurry is very important for producing a continuous natural gas hydrate, the flowability of this ice slurry is affected by the fraction of ice contained in the ice slurry.

Since the equilibrium pressure of natural gas hydrate and water is about 26 bar at the melting point of ice at 0 degrees Celsius, additional pressure is required to obtain a natural gas hydrate manufacturing rate above a certain level, but excessive pressure increases the manufacturing cost of the hydrate manufacturing reactor 22. In order to increase rapidly, the pressure pump 18 can boost the ice slurry to 50 bar to 70 bar so that the size of the subcooling for driving the formation of the hydrate is 6.5 to 9.7 degrees Celsius.

- the feed rate of the ice slurry can be easily adjusted by adjusting the supply amount of the ice slurry supplied to the pipe 36.
- the length of the pipe 36 may be determined by the diameter of the pipe 36, the conveying speed of the ice slurry, the amount of natural gas hydrate slurry to be produced, and the like. If the length of the pipe 36 is long, the installation space can be reduced by arranging the pipe 36 in a zigzag form.

Ice slurry may be supplied to maintain a constant space above the level 44 of the slurry.
- the pipe 36 of the hydrate manufacturing reactor 22 may further include a temperature sensor 48 located at the other end of the pipe 36 and measuring the temperature of the natural gas hydrate slurry at the position.
- the amount of natural gas hydrate slurry withdrawn to the second conduit 24 may be adjusted according to the temperature measured by the temperature sensor 48. For example, when the pressure in the hydrate manufacturing reactor 22 is 50 bar, when the temperature measured by the temperature sensor 48 is greater than 4 degrees Celsius, the withdrawal amount of the natural gas hydrate slurry is increased, and it is smaller than 2 degrees Celsius. In this case, it is possible to reduce the withdrawal amount of the natural gas hydrate slurry.
- the temperature range that determines the increase or decrease of the withdrawal amount of the natural gas hydrate slurry is the temperature of the medium of the natural gas hydrate slurry is 0 degrees Celsius, the melting point of the ice after the ice is exhausted as the ice slurry is transported and the natural gas hydrate slurry is gradually formed From the process of rising to 6.5 degrees Celsius, the equilibrium temperature can be selected a section in which the change in temperature relatively occurs.
- the second conduit 24 is connected at one end to the hydrate making reactor 22 so that the natural gas hydrate slurry is withdrawn.

- the second conduit 24 may be provided with a valve 32 to adjust the withdrawal amount of the natural gas hydrate slurry generated in the hydrate manufacturing reactor 22.
- the dehydration portion 26 is connected to the other end of the second conduit 24 to dehydrate the natural gas hydrate slurry. Since the natural gas hydrate slurry contains a large amount of water, water is separated through the dehydration unit 26 to generate natural gas hydrate powder. This natural gas hydrate powder may then be prepared as a natural gas hydrate in pellet form. In order to manufacture the natural gas hydrate powder in the form of pellets, the dehydration unit 26 may separate the natural gas hydrate slurry into a powder having 90% natural gas hydrate and a water content of 10% and water. The water separated in the dewatering unit 26 may be recovered to the ice slurry generating unit 16 through the raw material water recovery line 30 and used to manufacture the ice slurry. A back pressure regulator 34 may be interposed in the raw material water recovery line 30 to maintain the pressure of the dewatering part 26.
