Path-dependent morphology of CH₄ hydrates and their dissociation studied with high-pressure microfluidics

Abstract

Methane hydrates (MH) have been considered a promising future energy source due to their vast resource volume and high energy density. Understanding the behavior of MH formation and dissociation at...

Phase Transition Characteristics of Hydrate Formation Process in Microscale Pores

“…In the actual mining process, the size of pores would affect the phase equilibrium point of gas hydrate; furthermore, it affected parameter f eq ; there were differences in the microstructure of the generated hydrate, and parameter Δ E (θ) was also changed. A recent study also pointed that different paths of hydrate formation such as porous type and crystal type led to different morphology distribution, which indicated microstructure of hydrate was diverse and complex. Therefore, at the pore scale, if the distribution of P (Δ A i , j = 1 | A i , j = 0) could be easily obtained, the information on the reaction could be obtained by analyzing this parameter.…”
