Gas hydrates have endowed with great potential in gas storage

and rapid formation of gas hydrates is critical to use this novel technology. This work evaluated the natural gas hydrate formation process

which was compared from six parameters

including conversion of water to hydrate

storage capacity

the rate of hydrate formation

space velocity (SV) of hydrate reaction

energy consumption and hydrate removal. The literature was selected by analyzing and comparing these six parameters mentioned above

meanwhile placing emphasis on the three parameters of storage capacity

the rate of hydrate formation and space velocity of hydrate reaction. Through analysis and comparison

four conclusions could be obtained as follows. Firstly

the overall performance of the stirring process and the spraying process were better than other processes after analyzing the six parameters. Secondly

the additive types

the reactor structure and the reactor size had influence on the natural gas hydrate formation process. Thirdly

the energy consumption

via

reciprocating impact in the hydrate formation process was higher than that

via

stirring

spraying and static higee. Finally

it was one key for hydrate removal to

realize the hydrate industrial production.
