Method for inhibiting coalescence of hydrate slurry in decomposition process

The invention relates to the technical field of safe storage and transportation of natural gas, and discloses a method for inhibiting coalescence in a hydrate slurry decomposition process. The method comprises the following steps: (1) adding a hydrate decomposition stabilizer into a hydrate slurry system, and stirring; (2) raising the temperature to 1-2K below the hydrate phase equilibrium temperature corresponding to the system pressure, and carrying out first-stage decomposition; (3) raising the temperature to 0.5-1K above the hydrate phase equilibrium temperature corresponding to the system pressure, and carrying out second-stage decomposition; (4) raising the temperature of the system by 1.8-2.2 K, and carrying out third-stage decomposition; (5) raising the temperature of the system by 2.8-3.2 K, and carrying out fourth-stage decomposition; and (6) raising the temperature of the system to 298K or above to completely decompose the hydrate. According to the method, the decomposition process of the hydrate s
