“…The natural gas hydrate is widely distributed throughout the world, and the reserves are very rich. [130] The reserves are predicted from 3.1 Â 10 15 m 3 to 7.6 Â 10 18 m 3 (Nanhai 2017), and the reserves of hydrates in different regions are also different. [116,131,132] It is necessary to accurately determine the gas hydrate saturation.…”

Clathrate hydrates are formed by water molecules and natural gas molecules under a certain temperature and pressure. Natural gas hydrates are mainly distributed in the marine sediments and the permafrost in nature. As a kind of potential clean energy, determining the structural characteristics of hydrates in sediments is the prerequisite for the safe and economic exploitation of natural gas hydrate. X‐ray computed tomography (CT) is a potential method to nondestructively detect the occurrence of natural gas hydrate. The basic physical properties such as porosity, hydrate saturation, and sediment permeability of the hydrate‐bearing sediments are analyzed by calculating the CT numbers or combining with the network model. Therefore, the X‐ray CT is used to study the hydrates produced in the laboratory and the hydrates formed in the nature by scientists all over the world. By summarizing the previous research, this article focuses on the important role of X‐ray CT in the hydrate research from the following three aspects: analyzing the basic physical properties of hydrate sediment, identifying the occurrence mode of hydrate in sediments, and measuring the hydrate formation and decomposition process. In response to the research progress and future research directions, relevant suggestions had been put forward.

“…Compared to LNG and CNG, the risks of NGH transportation method is low because it is stored near atmospheric pressure so it is not explosive. [58,[61][62][63]. Hence, many experimental studies are necessary to provide optimum gas hydrate formation, storage and dissociation methods.…”

“…Hence, many experimental studies are necessary to provide optimum gas hydrate formation, storage and dissociation methods. Natural gas transportation as NGH includes three stages: production (gas hydrate formation), transportation and regasification [16,[61][62][63][64][65][66][67][68]. In NGH transportation method, first gas hydrate is formed by mixing water and natural gas (NG), then gas hydrates form at certain preparations conditions (0-20 o C and 2-6 MPa).…”

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.

“…Global estimates of the gas content in hydrate structures are within the range of ≈(1-5) × 10 15 (m 3 ) [4][5][6][7][8]. The works of many authors [9][10][11] provide information on the presence of GH natural sources in various geological structures. However, insufficient information on the properties of their formation and decomposition disturb development of gas hydrate technologies.…”

This paper presents the analysis of the main reasons for a significant decrease in the intensity of diffusion processes during the formation of gas hydrates; solutions to this problem are proposed in a new process flow diagram for the continuous synthesis of gas hydrates. The physical processes, occurring at the corresponding stages of the process flow, have been described in detail. In the proposed device, gas hydrate is formed at the boundary of gas bubbles immersed in cooled water. The dynamic effects arising at the bubble boundary contribute to the destruction of a forming gas hydrate structure, making it possible to renew the contact surface and ensure efficient heat removal from the reaction zone. The article proposes an assessment technique for the main process parameters in the synthesis of hydrates based on the criterion of thermodynamic parameters optimization. The optimization criterion determines the relationship of intensity of heat and mass transfer processes at the phase contact interface of reacting phases, correlating with the maximum GH synthesis rate, and makes it possible to determine optimum thermodynamic parameters in the reactor zone.
