Description
Technical Field
The utility model belongs to the technical field of gas hydrates, and particularly relates to a throttling type gas hydrate production device.
Background
Gas hydrate is a non-stoichiometric, ice-like clathrate formed by host (water) and guest (gas) molecules at low temperature and high pressure. The gases that may form the hydrates include methane, ethane, propane, CO2, H2S, and the like. With the continuous and deep research of gas hydrate technology, the research and application of technologies based on gas hydrate characteristics, such as carbon dioxide capturing and sealing, sea water desalination and mixed gas separation, natural gas storage and transportation, and the like, have been increasingly focused. However, in the industrial production and application process, the bottleneck of the related technology application based on hydrate generation is mainly that the requirement of the generation condition is high, the generation speed is slow, the induction time is long, the gas storage density is low, and the like. The key problem solved at present is to improve the generation rate and efficiency of the hydrate. The current methods of enhancing hydrate formation fall into two broad categories: chemical physical strengthening and mechanical strengthening. The chemical physical strengthening is mainly to add an accelerator to promote the generation of hydrate, and the accelerator comprises a thermodynamic accelerator and a kinetic accelerator. The mechanical strengthening method mainly comprises stirring method, bubbling method, spraying method, external field method, etc. The mechanical strengthening mainly increases the gas-liquid contact area and rapidly dissipates heat generated in the hydration reaction. At present, the stirring method has the disadvantages of large energy consumption, low gas storage density, easy abrasion and the like, is rarely used alone in industry, but is applied to most of static hydrate generation experimental devices; by adopting ultrasonic atomization, the gas-liquid contact area is increased, and the hydrate generation speed can be improved, but the ultrasonic atomizer added by the experimental system not only increases the investment cost, but also increases the operation cost required by the experiment.
Hydrate formation mainly includes two processes, nucleation and growth. Nucleation refers to the process of forming stable hydrate nuclei reaching a critical dimension when the solution is in a supercooled state or a supersaturated state, and entering a stable growth stage of the hydrate after the nuclei reach a certain critical dimension. Nucleation generally involves an induction period of time during which the nuclei are formed, with greater randomness and instability. In addition, in the process of generating the hydrate, a hydrate film can be formed to prevent gas from entering the water phase and the hydrate phase and prevent the generation of the hydrate. The conditions for hydrate formation are severe, which is also a difficulty for industrial application. In the experiment of generating the hydrate, a certain time is required to be spent for cooling, so that the condition of generating the hydrate is achieved, and the condition also means that energy is consumed for cooling and heat preservation. Therefore, there is a need for a device that accelerates hydrate formation under conditions that allow rapid cooling without the need for additional heat transfer media and that reduce intermediate energy consumption and that are in sufficient contact with water to rapidly achieve hydrate formation.
