“…Due to high gas and energy storage capacity of gas hydrates and their potential for separation processes, great attention has been paid to the positive applications of this technology (such as natural gas storage and transportation, gas separation, energy storage, water desalination, refrigeration systems, and so on (Adisasmito et al 1991;Chatti et al 2005;Eslamimanesh et al 2012;Javanmardi and Moshfeghian 2003;Ji et al 2001;Li et al 2012;Ohgaki et al 1996;Xu and Ge 2011;Tanii 1994), in recent years. However, high pressure/low temperature dissociation conditions, long induction time, and slow kinetic rate of hydrate growth are the major problems with using gas hydrates in gas industries (Babaee et al 2015;Mohammadi et al 2014a;Zhang et al 2008). Therefore, moderating the thermodynamic conditions and promoting the kinetics of gas hydrate formation are essential to benefit the positive applications of this technology and thus reliable design of hydrate-based industries.…”

“…In recent years, the kinetic parameters of clathrate hydrate formation (such as induction time, the quantity of gas uptake and growth rate) in the presence of different additives have been studied by many researchers (Arjang et al 2013;Bi et al 2009;Dashti et al 2015;Farhang et al 2014;Fazlali et al 2013;Ganji et al 2007a, b;Kang and Lee 2010;Kumar et al 2013;Lirio et al 2013;Manteghian et al 2013;Mohammadi et al 2014a;Ricaurte et al 2014;Rogers et al 2007;Roosta et al 2015;Sabil et al 2010;Torré et al 2011;Zhang et al 2004Zhang et al , 2007.

“…Mohammadi and coworkers studied the impact of sodium dodecyl sulfate and silver nanoparticles on the kinetic parameters of CO 2 clathrate hydrate formation (Mohammadi et al 2014a). Their results show that simultaneous utilization of SDS and silver nanoparticles increases the hydrate formation rate, storage capacity and the quantity of gas uptake during hydrate formation considerably (Mohammadi et al 2014a). Kang et al investigated the kinetic behavior of CO 2 hydrate formation in porous media in the presence of SDS.…”

In this communication, the impacts of adding SDS (sodium dodecyl sulfate), TBAF (tetra-n-butylammonium fluoride) and the mixture of SDS ? TBAF on the main kinetic parameters of CO 2 hydrate formation (induction time, the quantity and rate of gas uptake, and storage capacity) were investigated. The tests were performed under stirring conditions at T = 5°C and P = 3.8 MPa in a 169 cm 3 batch reactor. The results show that adding SDS with a concentration of 400 ppm, TBAF with a concentration of 1-5 wt%, and the mixture of SDS ? TBAF, would increase the storage capacity of CO 2 hydrate and the quantity of gas uptake, and decrease the induction time of hydrate formation process. The addition of 5 wt% of TBAF and 400 ppm of SDS would increase the CO 2 hydrate storage capacity by 86.1% and 81.6%, respectively, compared to pure water. Investigation of the impact of SDS, TBAF and their mixture on the rate of gas uptake indicates that the mixture of SDS ? TBAF does not have a significant effect on the rate of gas uptake during hydrate formation process.Keywords Semi-clathrate hydrate Á Gas hydrate Á Kinetics Á CO 2 Á SDS Á TBAF List of symbols P Pressure R Universal gas constant T Temperature V Volume of the gas phase Z Compressibility factor Subscripts 0 Conditions of the cell at time t = 0 i Counter t Time w Water

Gas hydrate concentration measurements on sucrose solutions using a new pilot test rig

et al. 2020

View full text Add to dashboard Cite

A new 750 cm3 pilot test rig based on the “isochoric pressure method” was designed and commissioned for the hydrate measurements to concentrate sucrose solutions. The reactor included an improved agitation system and enabled sampling of the sucrose solutions. The experimental method was validated be performing dissociation measurements for the CO2 + water system. Gas hydrate kinetic and sampling data were measured for the CO2 + sucrose solutions at sucrose concentrations between (12–60) oBrix, within the temperature range of (274.65–276.15) K and at pressures up to 3.70 MPa. Results showed that sucrose is a kinetic inhibitor. The data were modeled to obtain hydrate formation rate, storage capacity, gas consumption and apparent rate constant. Stage‐wise concentration measurements were performed with reactor conditions at 274.65 K, 3.70 MPa and 130 rpm mixer speed with liquid sample withdrawal. A final sucrose product of approximately 60 oBrix was obtained.

Gas hydrate/clathrate hydrate formation is an innovative method to trap CO2 into hydrate cages under appropriate thermodynamic and/or kinetic conditions. Due to their excellent surface properties, nanoparticles can be utilized as hydrate kinetic promoters. Here, the kinetics of the CO2 + tetra‐n‐butyl ammonium bromide (TBAB) semi‐clathrate hydrates system in the presence of two distinct nanofluid suspensions containing graphene oxide (GO) nanosheets and Al2O3 nanoparticles is evaluated. The results reveal that the kinetics of hydrate formation is inhibited by increasing the weight fraction of TBAB in aqueous solution. GO and Al2O3 are the most effective kinetic promoters for hydrates of (CO2 + TBAB). Furthermore, the aqueous solutions of TBAB + GO or Al2O3 noticeably increase the storage capacity compared to TBAB aqueous solution systems.
