The paper presents the first results of studying the kinetics of the formation of methane hydrates in dispersed frozen aqueous solutions of polyvinyl alcohol (FAS PVA) near the ice melting point under static conditions (without stirring). Based on the obtained experimental data, it was determined for the first time that using FAS PVA significantly (severalfold) decreases the time of conversion of much of the initial water into hydrate in comparison with dispersed ice. Furthermore, it was shown that the formation of gas hydrates in FAS PVA dispersions under static hydrate formation conditions can occur not only at higher rate but also at higher water-to-hydrate conversion in comparison with those in aqueous solutions of surfactants or in “dry water.”

在分散的冷冻聚乙烯醇水溶液中生产甲烷水合物

本文展示了在静态条件下（无搅拌）在接近冰熔点的聚乙烯醇 (FAS PVA) 分散冷冻水溶液中研究甲烷水合物形成动力学的初步结果。根据获得的实验数据，首次确定与分散的冰相比，使用 FAS PVA 显着（数倍）减少了大部分初始水转化为水合物的时间。此外，研究表明，在静态水合物形成条件下，FAS PVA 分散体中气体水合物的形成不仅可以以更高的速率发生，而且与表面活性剂水溶液或“干水。”
