Embodiment Construction
[0015] The gas hydrate production device adopted in the present invention is as figure 1 As shown, all parts of the device are insulated with thermal insulation materials. Water has a volume of 0.54m 3 The low temperature water tank 1 is kept at a temperature of 1-5°C, and an appropriate amount of hydrate formation accelerator is added through the dosing pipe 12. The accelerator consists of 5% cyclopentane and dodecylbenzenesulfonate with a concentration of 1200ppm in the total solution mass fraction. Sodium acid is prepared, and the mixture solution is called "rich water". The "rich water" is boosted to 8MPa with the booster pump 2, and the flow rate is 0.7L / min. The natural gas cooled to 2°C is mixed with the "rich water" at a molar ratio of 1:100 through the gas-liquid mixer 4. The bubble-like gas-liquid two-phase flow is formed through the spiral bubble generator 5, which increases the gas-liquid contact area and accelerates mass transfer. The ascending spiral coil pipe...
