Description
Technical Field
The invention relates to the technical field of gas separation and storage and transportation, in particular to a method for quickly hydrating and separating gas hydrate based on phase-change micro-nano fluid.
Background
At present, the development and utilization of coal mine gas are accelerated, and the method has important significance for ensuring the safe production of coal mines, increasing the supply of clean energy and reducing the emission of greenhouse gas. The gas hydration reaction separation process has the following two main processes:
1. constraints on heat transfer: since the formation of gas hydrates is an exothermic process, the heat generated during nucleation destroys the crystal nuclei, resulting in a slow growth of the crystal structure, in which heat transfer is a very important phenomenon. The hydrate has low heat conduction capability, and the heat generated by the hydrate cannot be effectively removed in time, so that the temperature of a gas hydration reaction system rises, and the gas hydration separation process is greatly weakened;
2. and (3) restriction of mass transfer: the gas and the water can not be fully contacted, and a plurality of multi-phase bodies form a plurality of phase interfaces, so that the mass transfer between gas phase and liquid phase in the system is seriously hindered, and the induction time is long and the hydrate generation rate is slow. The above problems result in long induction time, slow generation speed and large driving force of gas hydration reaction.
At present, the most mechanical strengthening method is to strengthen the generation of hydrate in a reaction kettle by stirring, the stirring mainly strengthens mass transfer and heat transfer, the liquid rotates along with blades, the gas-liquid contact area is increased, the gas dissolution efficiency is accelerated, and the heat generated by the generation of hydrate can be transferred in time. Further shortening the induction time of the hydrate, improving the generation rate, increasing the gas storage capacity and the like. The increase of stirring can increase the gas-liquid contact area, improve the gas hydration rate and ensure the fluid dispersibility. But the hydration reaction still stays at the gas-liquid interface, the induction time is not obviously shortened, and slight settlement and layering phenomena can be slightly generated in the kettle along with the increase of the experimental time, and the homogeneity is reduced although the particle suspension property can be met. In addition, the energy consumption of the system is increased by adding the blades for stirring, the system is not suitable for industrial production, and the danger of high-pressure gas leakage is increased by adding the stirring rotating shaft.
Therefore, in order to overcome the defects, a method for quickly hydrating and separating the gas hydrate based on the phase-change micro-nano fluid is needed.
