“…Remember that seawater has an average of 35000 ppm TDS [210,216]. The high TDS value (here salinity) of product water via CPH-based desalination is strongly related to the salts trapped in the hydrate crystals [6,10,27,36,118,[200][201][202][203][204][205][206][207][208][209][210][211][212][213][214]. This requires efforts on post-treatment process to completely remove trapped salt and therefore achieve product water with quality that meets the WHO drinking-water criterions.…”

This article presents a systematic review on the past developments of Hydrate-Based Desalination process using Cyclopentane as hydrate guest. This is the first review that covers all required fundamental data, such as multiphase equilibria data, kinetics, morphology, or physical properties of cyclopentane hydrates, in order to develop an effective and sustainable desalination process. Furthermore, this state-of-the-art describes research and commercialization perspectives. When compared to traditional applications, cyclopentane hydrate-based desalination process could be a promising solution. Indeed, it operates under normal atmospheric pressure, lower operation energies are required, etc… However, there are some challenges yet to overcome. A decision aid in the form of a diagram is proposed for a new cyclopentane hydrates-based desalination process. Hopefully, concepts reviewed in this study will suggest new ideas to advance technical solutions in order to make commercial hydrate-based desalination processes a reality.

“…Plus, the enormous amount of natural gas in the form of oceanic and permafrost gas hydrates are a promising future energy resource [9][10][11][12]. Recently, gas hydrates have attracted widespread attention due to diverse applications such as gas separation [13][14][15][16][17][18][19][20][21], CO 2 capture [22][23][24][25][26][27][28][29][30], water desalination [31][32][33][34][35][36][37][38], natural gas storage and transportation [39][40][41][42][43][44] and even planetary science [45][46][47][48]. For all above mentioned applications of clathrate hydrates, it is essential to increase our knowledge of thermodynamics, kinetics and the crystallization mechanisms of clathrate hydrates.…”

Gas hydrates are widely considered to be a crucial topic in oil and gas industries and attracting significant research due to potential applications such as gas storage, separation as well as water desalination. While the guest composition of hydrate phase is vital, due to the experimental difficulties in measuring hydrate composition, very little applicable information is available in the literature. Paradoxically, this is true, in spite of that; completing an experimental database on hydrate composition could have a significant impact on the processes design and modeling. Moreover, this should provide fundamental knowledge of kinetic effects as well as clarifying thermodynamic equilibrium. Hence, this paper was planned with the intent to fill in the gaps, classify and offer an overview of experimentally derived data on hydrate composition for literature. In addition, a thermodynamic model based on the van der Waals and Platteeuw approach and Kihara potential was utilized to simulate the hydrate composition along with equilibrium pressure. Previous experimental data shows that guest distribution in hydrate phase depends noticeably on the guest composition in vapor phase. In addition, composition of larger molecules, such as propane or butane, in the hydrate phase, is notably higher than in vapor phase. Our simulation results demonstrated that the hydrate composition data from direct measurement (microscopic tools) have been well evaluated by the thermodynamic model. Nevertheless, when structural transition can occur in a system, the thermodynamic model is no longer accurate. In the case of indirect measurements, the thermodynamic model usually predicts well the hydrate composition. Nonetheless, its capability does vary with differing hydrate composition and equilibrium pressure, to the extent that in some cases, it completely fails to predict hydrate composition. This could be due to kinetic effects on the enclathration of guest molecules during the crystallization, errors in experimental techniques to measure the hydrate composition or the model parameters like Kihara potential are not properly applied. Finally, these observations show that more reliable experimental database is needed to study the evolution of guest distribution in hydrate phase and some enhancements are required for the standard thermodynamic model.
