Title:
METHOD FOR STORING NATURAL GAS HYDRATE
Document Type and Number:
WIPO Patent Application WO/2020/124660
Kind Code:
A1
Abstract:
A method for storing a natural gas hydrate, comprising the following steps: (1) putting a porous medium and water having the same volume as pores of the porous medium in a micro-nano-scale limited space, and conducting sealing and standing so that water is absorbed by the porous medium to obtain a water-containing porous medium; (2) putting the water-containing porous medium in a reaction container, injecting a hydrate into the reaction container to generate required gas, and synthesizing the natural gas hydrate in the micro-nano-scale limited space; (3) storing the natural gas hydrate in the micro-nano-scale limited space under a normal pressure, i.e., realizing storage of the natural gas hydrate. By using unique physicochemical properties of water in the micro-nano-scale limited space and unique formation and decomposition dynamics properties of the natural gas hydrate in the micro-nano-scale limited space, a brand-new high-quality energy-saving safe and efficient natural gas hydrate storage and transportation method is provided.
