Abstract

The invention relates to an efficient continuous preparation method and an efficient continuous preparation device for a natural gas hydrate. The method comprises the following steps of: feeding water from a water supply pipe and a hydrate promoter from a medicating pipe into a low-temperature water tank together, cooling the mixture to a hydrate forming temperature through low-temperature water bath, and driving the mixture into a pipeline through a booster water pump; cooling natural gas from a gas inlet pipe through the low-temperature water tank, then charging the natural gas into a gas compressor, and mixing the water boosted by the booster water pump and carrying the promoter and the natural gas boosted by the gas compressor in a gas-liquid mixer together; feeding the gas-liquid mixture into a folding tubular reactor to perform spiral flow, fully mixing the gas and the liquid and exchanging heat, efficiently and continuously obtaining generated hydrate slurry, cooling the hydrate slurry in a hydrate separator to further generate a hydrate, then separating the hydrate, and feeding the separated hydrate into a hydrate storage tank. The method and the device have the advantagesof increasing the gas-water contact area, quickly removing hydrate generating heat and realizing efficient and continuous preparation of the natural gas hydrate under dynamic conditions, with the yield of 500kg / h.

Description

technical field [0001] The invention relates to a high-efficiency continuous preparation method and device for natural gas hydrate. Background technique [0002] Natural gas hydrate is a crystalline cage substance formed by natural gas and water under certain temperature and pressure conditions. In standard state, 1m 3 Gas hydrates can release 164m 3 of methane gas. Therefore, hydrate is a high-density energy substance. In addition, it also has the characteristics of simple preparation technical conditions, stable performance, and safe storage. It has good industrial prospects in natural gas storage and transportation. In order to realize the rapid preparation of hydrates, it is hoped that the formation of gas-hydrates can be accelerated and the productivity can be increased. Therefore, it is of great significance to develop efficient and continuous synthesis technology and process of natural gas hydrate. [0003] At present, the main obstacle to the industrial applicat...
