Abstract

Clathrate or gas hydrates have gained tremendous interest due to their potential applications in various industries and flow assurance problems in the oil and gas sector. In both directions, salinity plays an essential role in controlling the kinetics/thermodynamics of hydrate formation/dissociation. Therefore, it is critical to understand: (i) the exact impact of salts, either as promoters or inhibitors of hydrate formation and their mechanism of action, (ii) exclusion or inclusion of salts from the gas hydrate framework, and (iii) factors determining the effect of salts (e.g., pressure, temperature, type of guest molecules, and hydrate structures). This review gathers the macro and microscopic level literature while incorporating the experimental and molecular dynamic simulations to explain the conflicting views on the effect of salt ions in gas hydrate research. The overall objective of this review is to fill the knowledge gap between experimental and theoretical efforts examining the influence of salt chemistry on hydrate nucleation, growth and dissociation phenomena.

盐度在包合物水合物工艺中的作用

包合物或天然气水合物由于其在各个行业的潜在应用以及石油和天然气领域的流动保证问题而引起了极大的兴趣。在这两个方向上，盐度在控制水合物形成/解离的动力学/热力学中起着重要作用。因此，理解以下内容至关重要:(i)盐作为水合物形成的促进剂或抑制剂的确切影响及其作用机制;(ii)在天然气水合物框架中排除或包含盐;(iii)决定盐作用的因素(例如压力、温度、客体分子类型和水合物结构)。本文收集了宏观和微观层面的文献，结合实验和分子动力学模拟来解释盐离子在天然气水合物研究中的作用的矛盾观点。本综述的总体目的是填补实验和理论研究之间的知识空白，研究盐化学对水合物成核、生长和解离现象的影响。

期刊介绍： The objective of the Journal of Natural Gas Science & Engineering is to bridge the gap between the engineering and the science of natural gas by publishing explicitly written articles intelligible to scientists and engineers working in any field of natural gas science and engineering from the reservoir to the market. An attempt is made in all issues to balance the subject matter and to appeal to a broad readership. The Journal of Natural Gas Science & Engineering covers the fields of natural gas exploration, production, processing and transmission in its broadest possible sense. Topics include: origin and accumulation of natural gas; natural gas geochemistry; gas-reservoir engineering; well logging, testing and evaluation; mathematical modelling; enhanced gas recovery; thermodynamics and phase behaviour, gas-reservoir modelling and simulation; natural gas production engineering; primary and enhanced production from unconventional gas resources, subsurface issues related to coalbed methane, tight gas, shale gas, and hydrate production, formation evaluation; exploration methods, multiphase flow and flow assurance issues, novel processing (e.g., subsea) techniques, raw gas transmission methods, gas processing/LNG technologies, sales gas transmission and storage. The Journal of Natural Gas Science & Engineering will also focus on economical, environmental, management and safety issues related to natural gas production, processing and transportation.
