Experimental Analysis on the Probability Density Distribution of Methane Hydrate Induction Times in Porous Media
Abstract Hydrate‐based natural‐gas transport and storage have been proposed and developed because of the high safety and low cost, and hydrate reformation is a serious barrier for high‐efficiency natural‐gas hydrate exploitation. The hydrate formation induction time is a crucial kinetic parameter fo...

Abstract Hydrate‐based natural‐gas transport and storage have been proposed and developed because of the high safety and low cost, and hydrate reformation is a serious barrier for high‐efficiency natural‐gas hydrate exploitation. The hydrate formation induction time is a crucial kinetic parameter for both of the two fields. To clarify the hydrate formation and/or reformation induction characteristics, the effects of sub‐cooling, particle size, initial water saturation and memory effect on the stochastic induction time patterns are experimentally investigated. In total, 22 cases were performed, and each case was repeated in 20–30 runs under identical conditions. The experimental results show that the distribution of CH 4 hydrate induction times can be properly fitted to a lognormal distribution function. Larger sub‐cooling leads to shorter induction time and more repeatable experimental results.
