Effect of silica sand size on the formation kinetics of CO2 hydrate in porous media in the presence of pure water and seawater relevant for CO2 sequestration
TL;DR: In this article, the authors focused on understanding the kinetics of CO2 hydrate formation in pure water and seawater at an initial formation pressure of 6 MPa (providing a driving force of about 4.0 MPa) and a formation temperature of 276.15 K with 75% water saturation in three silica sand particle sizes (0.16 mm, 0.46 mm and 0.92 mm).

Kinetics of methane hydrate formation in an aqueous solution of thermodynamic promoters (THF and TBAB) with and without kinetic promoter (SDS)
TL;DR: In this article, experiments were conducted at an initial pressure conditions of 75 MPa and 27615 K for pure water, SDS, TBAB, (Tetra-n-butyl ammonium bromide, tetrahydrofuran, THF) and kinetic promoters (sodium dodecyl sulphate SDS) for methane hydrate system suitable for natural gas storage and transportation.
Journal ArticleDOI
Influence of thermal stimulation on the methane hydrate dissociation in porous media under confined reservoir
TL;DR: In this article, the authors have developed a replica of natural hydrate-bearing atmosphere in a laboratory scale experimental set-up and examined the silica sand size effect on the formation and gas recovery in the presence of both pure water and seawater under confined reservoir conditions.
Journal ArticleDOI
Thermodynamic phase equilibrium of single-guest hydrate and formation data of hydrate in presence of chemical additives: a review
TL;DR: In this paper, a review of single-guest hydrate phase equilibrium data and also hydrate equilibrium in presence of chemical additives, which operate as inhibitors, promoters, or both together, is presented.
