In gas clathrate hydrates, inclusion gas molecules stabilize crystalline water structures. In addition to being fundamentally interesting, gas hydrates attract significant practical attention because of their possible application in various high-tech technologies. However, gas hydrates pose health, safety, and environmental risks when they form within oil and gas pipelines, as well as within hydrocarbon-producing and treatment facilities. Among available strategies to control and sometimes prevent hydrate plug formation is the use of surface-active low-molecular-weight compounds, known as antiagglomerants (AAs). AAs prevent the agglomeration of small hydrate particles into large plugs. It is not clear whether AAs promote or frustrate hydrate growth. We present two molecular mechanisms by which AAs promote and frustrate, respectively, hydrate growth. Our results could lead to innovative methodologies for managing hydrates in high-tech applications, as well as for securing the safety of oil and gas operations.

抗结块剂影响天然气水合物的生长

在气体包合物水合物中，夹杂物气体分子可稳定结晶水结构。除了从根本上引起人们关注之外，天然气水合物还因其在各种高科技技术中的应用而备受关注。但是，天然气水合物在石油和天然气管道以及烃生产和处理设施中形成时，会构成健康，安全和环境风险。在控制和有时防止水合物塞形成的可用策略中，一种是使用表面活性的低分子量化合物，即抗凝聚剂（AA）。AAs可以防止小水合物颗粒聚集成大塞子。尚不清楚AA是否促进或阻碍水合物的生长。我们介绍了AA促进和挫败的两种分子机制，水合物的生长。我们的结果可能会导致创新的方法论，以管理高科技应用中的水合物，并确保石油和天然气运营的安全性。
