“…If present, it needs to be removed via a secondary treatment step, since surfactants such as SDS are known to significantly contribute to the toxicity of some effluents and are harmful to humans, marine life, and the environment. It would be desirable to identify suitable eco-friendly kinetic promoters such as amino acids [41][42][43], starch [44,45], biosurfactants [46], or a different co-guest gas with propane in the future for the HyDesal process.…”

Water is a key resource for sustainable development and plays a crucial role in human development. Desalination is one of the most promising technologies to mitigate the emerging water crisis. Thermal desalination and reverse osmosis are two of the most widely employed desalination technologies in the world. However, these technologies are energy intensive. Clathrate-hydrate-based desalination (HyDesal) is a potential energy-efficient desalination technology to strengthen the energy–water nexus. In our previous study, we proposed a ColdEn-HyDesal process utilizing waste Liquefied Natural Gas (LNG) cold energy based on a fixed-bed reactor configuration. In this study, we evaluated the effect of 10% propane in three different gas mixtures, namely, nitrogen (G1), argon (G2), and carbon dioxide (G3), as hydrate formers for the HyDesal process. The achieved water recovery was very low (~2%) in the presence of NaCl in the solution for gas mixtures G1 and G2. However, high water recovery and faster kinetics were achieved with the G3 mixture. To improve the water recovery and kinetics of hydrate formation for the G2 gas mixture, the effect of sodium dodecyl sulfate (SDS) was evaluated. The addition of SDS did improve the kinetics and water recovery significantly.

“…Hence, in the history of clathrate hydrates, the focus has always been on how to prevent hydrate formation in oil and gas pipelines. However, clathrate hydrates have received much attention in over the last two decades due to their potential applications such as gas separation (Hashimoto et al, 2017;Tomita et al, 2015), gas storage and transportation (Babakhani & Alamdari, 2015;Ganji et al, 2013;Kumar et al 2019), CO2 capture sequestration (Duc et al, 2007, ;Oya et al, 2017;Prah & Yun, 2017), etc. Furthermore, natural gas hydrates in permafrost regions and oceanic sediments may represent a new source of sustainable energy (Kvenvolden, 1988;Makogon, 2010).…”

Interest of Clathrate hydrates for industrial applications is rising. While numerous studies can be found on carbon capture or desalination, this effort investigates thermodynamics of the combined process using cyclopentane (CP) as second guest molecule. This document provides numerous equilibrium data of mixed CP/CO2 hydrates in presence of salt (NaCl, KCl) under differents concentrations. Final dissociation points are collected, as well as intermediate dissociation points in presence of hydrates. While the first provide equilibrium data, the others are not at equilibrium. Indeed, Results show that, in presence of salts, several crystallization events occur in the system. Consequently, multiple hydrate structures could be formed in the bulk, such as pure CO2 hydrates and mixed CO2/CP hydrates Finally, van der Waals and Platteeuw approach has been used and furnishes results within 0.4K uncertainty compared to this work and within 0.5K compared to literature. Besides, thermodynamic consistency of data has been evaluated.

“…On the other hand, extracts of tomato were showing significantly lesser clathrate conversion, similar to the pure water system. Fakharian et al 17 and Babakhani and Alamdari 18 have also investigated the methane storage capacity and the stability of methane hydrates using water-soluble starch from potato and maize. They inferred that these systems are capable of forming hydrates in a way similar to sodium dodecyl sulfate (SDS).…”

Methane (CH 4 ) and carbon dioxide (CO 2 ), the important greenhouse gases, are capable of forming clathrate hydrates under some suitable thermodynamic conditions. The gas storage capacity of these materials is high, and therefore they are often useful in gas storage applications. Certain expensive and toxic chemicals are employed to accelerate/decelerate the process. In this study, we report rapid (∼30–50 min) and effective (∼80%) methane hydrate conversion in the presence of three naturally occurring additives such as dry powders from Nelumbo nucifera (Indian lotus), Piper betle (betel), and Azadirachta indica (neem), at lower concentrations (0.5 wt %). Obtained results were carefully compared with the well-known kinetic promoter (sodium dodecyl sulfate). All the biomaterials are equally good kinetic promoters for methane hydrates, although the required subcooling is significantly large. However, no hydrate formation is observed with CO 2 gas.
