Embodiment 1

[0029] Using the hydrate synthesis reaction kettle provided by the present invention, combined with the supporting pressurization system, data acquisition system, feeding system, etc. to synthesize artificial natural gas hydrate, the design pressure of the reaction kettle is 20MPa, and the design temperature is -15°C~40 ℃, the size of the kettle is Φ950mm×1200mm, the total volume of the cavity is 850L, the diameter of the water injection hole is 25mm, and the diameter of the stirring rod is 50mm.

[0030] Using the reactor to synthesize artificial natural gas hydrate, the process is as follows:

[0031] First, add appropriate sand into the reactor, and buckle the upper flat cover of the reactor, then pour in an appropriate amount of water, turn on the stirring rod, cool the reactor, and then add air to the reactor until the required pressure. Since the stirring rod is turned on during the gas filling process, part of the gas passes through the stirring rod and is ejected in t...

Abstract

The invention discloses a natural gas hydrate synthesis reaction kettle, which is mainly formed by a cylinder body 8, an upper flat cover head 9, a lower flat cover head 10, a temperature sensor 12, apressure sensor 13 and a stirring rod 6. The cylinder body 8 as well as the upper flat cover head 9 and the lower flat cover head 10 are fixedly combined into a reaction kettle body, and the upper flat cover head is provided with a gas inlet and outlet 2, the temperature sensor 12 and the pressure sensor 13; the lower flat cover head 10 is provided with a liquid outlet 5, and the side wall of thecylinder body 8 is provided with a liquid inlet 4; the stirring rod 6 and blades 7 are arranged in the kettle body, and a hollow channel 14 is arranged inside the stirring rod; four to eight air inlets 20 are horizontally distributed in the middle upper part of the stirring rod, and the blades 7 are also of hollow structures, and are communicated with the hollow channel of the stirring rod; air holes 18 with different diameters are distributed in the liquid backing surfaces of the blades. The natural gas hydrate synthesis reaction kettle provided by the invention has the advantages of reliable principle and simple operation, can effectively improve the gas-liquid contact area of the hydration reaction process and improve the hydration reaction efficiency, and can also be widely used in the related fields of the chemical industry, the petroleum and natural gas industries and the like.

Description

technical field [0001] The invention relates to a natural gas hydrate synthesis reaction kettle, which belongs to the field of new energy exploitation. Background technique [0002] Natural gas hydrate is an ice-like non-stoichiometric cage-type crystalline substance formed by natural gas and water at low temperature and high pressure. It is also called "combustible ice" because it is ignitable and flammable at normal temperature and pressure. At present, scientists from various countries have reached a relatively consistent conclusion on the global natural gas hydrate resources as 2×10 16 m 3 , its organic carbon accounts for about 53.3% of the global organic carbon, while the sum of coal, oil, and natural gas only accounts for 26.6%. Therefore, natural gas hydrate is considered to be the most important potential energy in the 21st century, and it has great attraction in today's energy crisis. [0003] In nature, gas hydrates are mainly distributed in loose sediments on ...
