The first paper of this study discussed the development of the Hu‐Lee‐Sum (HLS) correlation and demonstrated the generality and universality of the correlation to predict structure I hydrates suppression temperature for any single salt system. However, natural gas commonly forms structure II hydrates, and mixed salts naturally occur in oil and gas production. Therefore, reliable prediction of structure II hydrates suppression temperature in presence of mixed salts over a wide range of pressure is considerably important. The contribution for each salt in salt mixtures is accounted for in the effective mole fraction to extend the HLS correlation for mixed salts systems. Moreover, a parameter (α) is introduced to account for the effect of hydrate structure on the hydrate suppression temperature. Herein, the HLS correlation is further shown to be universal and reliable to predict the hydrate suppression temperature for more complicated systems for mixed gases and mixed salts. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2240–2250, 2018

抑制系统的天然气水合物抑制温度的普遍相关性：II。混合盐和结构类型

这项研究的第一篇论文讨论了Hu-Lee-Sum（HLS）相关性的发展，并证明了相关性的普遍性和普遍性，以预测结构I水合物对任何单一盐体系的抑制温度。但是，天然气通常会形成结构II的水合物，而混合盐自然会在油气生产中产生。因此，在广泛的压力范围内可靠地预测结构II的水合物抑制温度是很重要的。盐混合物中每种盐的贡献以有效摩尔分数解释，以扩展混合盐系统的HLS相关性。此外，引入参数（α）以说明水合物结构对水合物抑制温度的影响。在此处，在更复杂的混合气体和混合盐体系中，HLS相关性被进一步证明是通用且可靠的，可以预测水合物抑制温度。©2018美国化学工程师学会AIChE J，64：2240-2250，2018年
