“…One advantage of semi-clathrates in storage purposes is that it allows for more guest molecules compared to promoters like THF, which do not alter the cage. Li et al [62] examined a hydrate-based CO2 separation process from a fuel gas mixture and observed that TBAB range of 0.14-1.00 mol% increased the induction time and hydrate growth rate while also increasing CO 2 storage capacity of the clathrate.…”

The clathrate hydrates represent a distinctive, unusual, scientifically significant, and practically important class of solid state materials. Since their discovery in the early nineteenth century, their widespread distribution in oceans and permafrost regions and their ability to trap atoms and small molecules-particularly methane and other small hydrocarbons-has led to the realization that they are simultaneously a tremendous energy source and, in the face of global warming, a potential greenhouse gas release disaster of unprecedented magnitude just waiting to happen. In the twentieth century, it was realized that solid methane clathrate hydrate could plug natural gas pipelines and disrupt oil drilling processes. On the environmental positive side, clathrate hydrates can store hydrogen and sequester carbon dioxide. A brief historical review of the formation, structure, and uses of clathrate hydrates forms the backdrop for a discussion of modern scientific investigations of these solids employing spectroscopy, structure determination methods, isotopic studies, computational-theoretical modeling, and interrogations of guest-host interactions via special guests. For example, the use of colored halogens in clathrate hydrate hosts enables UV-visible spectroscopic methods to be employed to study clathrate hydrate structure.

“…A self-contained storage vessel consisting of a low-temperature-grade carbon steel coded vessel and insulation and control systems equipped with approved class valves, piping, and fittings was considered. So far, CO2 separation and capture from waste gas by means of CO2 hydrate has been proposed [8][9][10]. Figure 7 shows the CO2 hydrate production system [11].…”

Climate change caused by global warming has become a serious issue in recent years. The main purpose of this study was to evaluate the effectiveness of the above system to quantitatively supply CO2 or CO2 hydrate from industrial to agricultural areas. In this analysis, several transportation methods, namely, truck, hydrate tank lorry, and pipeline, were considered. According to this analysis, the total CO2 supply costs including transportation ranged from 15 to 25 yen/kg-CO2 when the transportation distance was 50 km or less. The cost of the hydrate-based method increased with the transport distance in contrast to the liquefied CO2 approach. However, the technology of supplying CO2 hydrate had merit by using a local cooling technique for cooling specific parts of agricultural products.

“…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).…”

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
