“…The induction time of hydrate increases with the shrinkage of pore size. 52 In addition, porous media can seal the gas produced from hydrate dissociation and provide more gas−liquid contact space for secondary hydrate formation. 53 In this study, the phenomenon of secondary hydrate formation was observed within a microfluidic chip with porous media as follows:…”

With the emergence of natural gas hydrates (NGHs) as a crucial transition energy, understanding the gas–water flow mechanisms is essential for the exploitation of NGHs. A 2.5D microfluidic chip device was used to visualize the real-time dissociation process of methane hydrate and methane–tetrahydrofuran hydrate. This allowed us to perform a morphological analysis of the in situ dissociation process of hydrate. We quantitatively analyzed the distribution of dissociated methane bubbles to describe the hydrate dissociation behavior, and the results found that the initial distribution of formed hydrates and the denseness of hydrates are critical for the formation of gas–water flow channels. The initial distribution of the gas–water channels determines the dissociation priority and speed. Hydrate dissociation and secondary formation in the methane–tetrahydrofuran system significantly differ from those in the methane–pure water system. This work provides a new approach to study the microscopic control mechanism of fluid flow during the phase change of NGHs.

Hydrate-based CO 2 storage/sequestration (HBCS) technique could potentially fulfill the mandate of the Sustainable Development Goal (SDG) 13 toward efficient and safe storage of CO 2 through successful lab-scale experimentation in overcoming the existing storage capacity challenges. In this article, we carefully reviewed and discussed the reported fundamental lab-scale experimental attempts to successfully store CO 2 as hydrate in sediments. The CO 2 hydrate formation thermodynamics, kinetics, and mechanism insights in porous media are critically discussed to reveal the state of the art and the current challenges facing the implementation of the HBCS technique and provide guidelines and pathways toward a high CO 2 storage capacity. In addition, factors affecting CO 2 hydrate formation and hydrate formation mechanisms in various types of porous media are discussed. Factors that mainly control the CO 2 storage capacity in porous media are driving force, porosity, capillary effect, gas and liquid permeability, particle size, and surface area. However, mass transfer limitation, potential storage site, CO 2 transportation, CO 2 injection technique, cost, environmental constraints, and CO 2 stability are the main challenges toward the technological readiness of the HBCS. The findings in this work provide useful guidelines and pathways which could lead to an increase in CO 2 storage capacity as hydrate for cleaner earth in the future.

“…Pure CO 2 hydrate belongs to structure I due to the small CO 2 molecule diameter of 5.12 Å . If all the cavities were filled, 1 m 3 of CO 2 SI hydrate could contain approximately 180 m 3 of CO 2 gas at standard state . This is one of the reasons that hydrate technology is feasible in CO 2 capture, separation and transportation .…”

As a result of growing concerns about global warming, hydrate‐based processing is becoming a promising technology for CO2 capture. This process captures CO2 by forming clathrate hydrates by exposing flue gas to water under suitable conditions. It results in high CO2 recovery due to its large gas‐storage capacity and the large concentration differences between the separation phases. However, the high cost of hydrate formation conditions is the main reason preventing this technology from wide industrial application. To address this issue, this paper explores the literature on the current status of developments in hydrate‐based CO2 capture and separation, focusing on methods to mitigate hydrate formation conditions and to improve phase‐contacting performance. In this review, various relevant aspects of CO2 capture and separation selectivity are summarized, including promoter selection, thermodynamic and kinetic model development, reactor configuration, and process design. Advantages and disadvantages of alternative processes are also discussed. Current studies are limited to laboratory experiments but low energy penalties and high CO2 selectivity features of hydrate processes will make future plant implementation feasible. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
