“…1,3-dioxolane (DIOX) is a heterocyclic compound closely related to THF, where the carbon atom at 3-position of THF has been replaced with an oxygen atom. 25 It has similar water solubility as THF, but is less volatile and less toxic (Table S1 in the Supporting Information (SI)). DIOX by itself, stabilizes the sII hydrate.…”

“…In order to determine clathrate occupancy in given equilibrium conditions of pressure and temperature, it is first necessary to estimate HQ solubility in the chosen solvent at the same conditions. The experimental apparatus used for this determination was initially developed and used by Torréet al 25 to follow up gas hydrate formation. This apparatus consists of a titanium cylindrical vessel as reactor, equipped with two see through sapphire windows of 20 mm diameter each that allow lighting inside the reactor and making visual observations thanks to a CCD camera (OptiaII model from Creative Laboratories).…”

Experimental Determination of Phase Equilibria and Occupancies for CO₂, CH₄, and N₂ Hydroquinone Clathrates

Hydroquinone (HQ) forms organic clathrates in the presence of various gas molecules in specific thermodynamic conditions. For some systems, clathrate phase equilibrium and occupancy data are very scarce or inexistent in literature to date. This work presents experimental results obtained for the CO 2 −HQ, CH 4 −HQ, and N 2 − HQ clathrates, in an extended range of temperature from about 288 to 354 K. Formation/dissociation pressures, and occupancies at the equilibrium clathrate forming conditions, were determined for these systems. Experiments showing the influence of the crystallization solvent, and the effect of the gas pressure on HQ solubility, were also presented and discussed. A good agreement is obtained between our experimental results and the already published experimental and modeling data. Our results show a clear dependency of the clathrate occupancy with temperature. The equilibrium curves obtained for CO 2 −HQ and CH 4 −HQ clathrates were found to be very close to each other. The results presented in this study, obtained in a relatively large temperature range, are new and important to the field of organic clathrates with potential impact on gas separation, energy storage, and transport.

“…Tetrabutylammonium bromide, as a traditional thermodynamic promoter, has been used extensively in CO 2 hydrate formation. An increase in TBAB concentration could significantly accelerate hydrate formation, reduce equilibrium pressure, and shorten the induction time . The influence of different promoters on phase equilibrium is summarized in Table .…”

“…An increase in TBAB concentration could significantly accelerate hydrate formation, reduce equilibrium pressure, and shorten the induction time. [36][37][38] The influence of different promoters on phase equilibrium is summarized in Table 1. On the one hand, hydrate formed with TBAB addition has empty dodecahedral cages that can selectively trap CO 2 gas molecules and improve the separation efficiency.…”

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.
