The technology of natural gas hydrate storage and transport involves hydrate production,transportation and regasification process.Among them,the hydrate production and transportation are the key issue.In this study,six sizes of ice particles are used to simulate the methane hydrate formation,and the dissociation experiment of methane hydrate is carried out at different temperatures.Based on experimental data,we find out that the smaller the ice particle is,the easier the hydrate is to form and the shorter the formation time is under the same experimental conditions.But during the dissociation process,the methane hydrate formed from the bigger size of ice particle shows the self-protection and keep the long term sub-stable status and no dissociation at two different temperatures.Therefore,we proposes that the best sizes of ice particle to form natural gas hydrate and temperature of -4℃ for storage and transport gas hydrate would be chosen during its storage and transport.
