“…Dry water, a free-flowing powder prepared by mixing water and hydrophobic silica nanoparticles, has been recently introduced as kinetics and thermodynamic promoter [2,7,8,14,15,[32][33][34][35][36][37]. Dry water as a special encapsulated product has been resembled to reverse micelle and microemulsion systems that are formed by hydrophobic nanoparticles surrounding an aqueous core suspended in a nonpolar medium such as air [33,38].…”

The synergic effects of four combinations of nano dry gels plus tetrahydrofuran (THF) on the CO 2 capture and hydrate phase equilibrium were investigated. It was found that the hydrate phase equilibrium condition was almost identical with the mixture of nano dry gel + THF and THF solution. The gas storage capacity and CO 2 uptake rate increased significantly by THF concentration increment up to 19.06 wt % in the dry gel structure compared to a similar THF solution. The hydrate induction time decreased at higher ratios of THF. The mixture of dry gel + THF acted as a stabilizer during the hydrate dissociation process. Considering the gas storage capacity, kinetics, and thermodynamic promoting effect, a mixture including 19.06 wt % THF was favorable for hydrate-based CO 2 capture compared to the other combinations investigated in this study.

“…For transportation purposes of gas hydrates, there is a tendency to speed up hydrate formation by increasing gas-water contact. This can be done by adding some chemicals to promote hydrate formation mainly by changing the surface tension in the system [75][76][77]. Nonetheless, it is important to remind that these chemicals are mostly environmentally harmful so necessary precautions should be taken.…”

The dependence of industry on natural gas has increased a lot last decades so the transportation of natural gas has become one of the most important issue in natural gas industry. Although the formation of natural gas hydrate is a problem in natural gas pipelines, the transportation of natural gas as natural gas hydrates by ships or trucks is an advantage. Therefore, in this study, first, the studies related to the inhibition of natural gas hydrate in pipelines are reviewed because there are many gas pipeline projects so natural gas hydrate inhibition is an important issue in natural gas industry. Then, the studies related to the transportation of natural gas as natural gas hydrates are reviewed in this study because this is a new subject and for the future, if research and development in this transportation method could be done successfully, this method might be better alternative compared to LNG and CNG natural gas transportation methods.

“…Among the studies involving solid adsorbents, it has recently been reported the use of adsorbents with high humidity to increase the CH 4 storage capacity on clathrate hydrates forms [52][53][54]. This alternative also respects strict conditions of temperature and pressure, and shall respect the need for lower temperatures (close to 273 K) and the supply of guest molecules in the presence of moisture [55,56]; however, methane storage capacities from the formation of hydrates are consequently higher in higher pressures, and may surpass the 200 V/V in meso and macroporous adsorbents saturated with water.…”

SUMMARYAs natural gas, biogas has been used for nobler purposes in recent years, such as the use of purified biogas (biomethane) in the transport sector. Currently, natural gas storage for use in transportation is accomplished primarily through compressed natural gas (CNG) technologies and liquefied natural gas (LNG), which require large amounts of energy. In recent years, the storage technology of absorbed natural gas (ANG) on porous materials has been studied, fundamentally highlighted by reduced energy use and increased safety in the transport of gaseous fuel. In this sense, the present study aimed to gather information about the main adsorbent materials which are being studied and the conditions normally employed in surveys that use ANG technology, as well as pointing out the main challenges for the storage of biogas in the adsorbed form at low pressures and room temperature in an attempt to meet the target of 180 V/V established by Department of Energy. Researchers reported high storage capacities in moderate conditions of temperature and pressure; however, the biggest challenge of the research involving methane adsorbed is also achieving high rates of desorption with the lowest possible energy expenditure.
