[0032] The specific implementation plan is as follows:
[0033] Under the set pressure, the natural gas vented from the oil field enters the stirred hydrate reactor 2 through the inlet channel 1 at a speed of 1.0~2.5m / s, and at the same time, the solution containing the kinetic promoter SDS is passed through the inlet 5 The annular liquid inlet pipe 4 enters the stirred hydrate reactor 2, where the concentration of SDS is controlled within the range of 300~500mg / L, 500mg / L is the best; the stirred hydrate reactor adopts external water-cooled jacketed cooling, That is, the water-cooled jacket 6 is placed in the cavity formed by the double-layer casing to achieve the cooling effect. The temperature of the stirred hydrate reactor is controlled at 0.5~4℃, and the pressure in the stirred hydrate reactor 2 is controlled at 1. Within the range of ~4MPa, after sufficient hydration reaction, H in natural gas 2 S and CO 2 When the acid gas is solidified in the hydrate, the formed hydrate i...
