Special Issue Information

Dear Colleagues,

Gas hydrates have been gaining increasing research interest in recent years given their nature as an exploitable energy resource, their promising applications in gas storage and separation, seawater desalination, refrigeration, and the risk they pose to oil and gas pipeline flow assurance. Despite the extensive progress made to date, however, several knowledge gaps related to gas hydrates remain to be filled, which include the scale-up of gas hydrate technology, physicochemical properties of gas hydrates (surface chemistry, nucleation micro-mechanism and characterization, structures at ultra-high pressures and under confinement), economical and green gas hydrate risk management strategies, efficient production of gas hydrate reservoirs. Therefore, authors are invited to submit manuscripts to this Molecules Special Issue, titled “Advance in Gas Hydrates: Formation, Structures, Properties and Applications”, in which all innovative aspects of gas hydrates valuable to the industry or academia are discussed, such as hydrate physicochemical properties, formation and dissociation, modeling, phase behavior, structures, promotion and inhibition, transportability, molecular simulation, exploitation, reaction system design and optimization. This Special Issue aims to advance the understanding of gas hydrates and offers new insight into gas hydrate applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).

The hydrate blockage avoidance performance of two anti-agglomerants (coconut amidopropyl dimethylamine, propylene bis (octadecylamidopropyl dimethylammonium chloride)) and their mixtures with polyvinylpyrrolidone (PVP) was tested in a high-pressure rocking cell apparatus. The effect of gas–liquid ratio, water content and PVP concentration were analyzed. A method for evaluating the kinetic inhibiting and anti-agglomerating performance of hydrate inhibitors was established. It was found that coconut amidopropyl dimethylamine had good anti-agglomerating performance at a low gas–liquid ratio (0.5) and various water content levels (20~80%), while propylene bis (octadecylamidopropyl dimethylammonium chloride) had a good anti-agglomerating performance only at a low gas–liquid ratio (0.5) and high water content (80%), and the hydrate volume fraction was up to 23.27% for good anti-agglomeration. When PVP was mixed with the above two anti-agglomerants, it was found that coconut amidopropyl dimethylamine could significantly reduce the kinetic inhibition performance of PVP, while propylene bis (octadecylamidopropyl dimethylammonium chloride) had no significant effect on the kinetic inhibition performance of PVP. The maximum subcooling was 4.4 °C. PVP had no significant effect on the anti-agglomerating performance of the two anti-agglomerants, and the maximum hydrate volume fraction was 18.87% when the agglomeration was well inhibited.
