WebOct 4, 2024 · The accurate simulation of upward multiphase flow of hydrate slurry in the annulus is one of the key scientific unsolved issues in natural gas hydrate solid fluidization exploitation. In this work, the upward multiphase flow of hydrate slurry in a vertical concentric annulus is simulated. WebApr 28, 2024 · The hydrate growth was suggested to start with the formation of unsaturated hydrate nuclei followed by gas adsorption. In hydrate formed from all tested gases, CO 2 concentrations in hydrate nuclei were found to be 23-33% of the saturation state. In the flue gas system, the N 2 concentration reached a saturation state once hydrate nuclei formed.
