The present work deals with a review of single-guest hydrate phase equilibrium data and also hydrate equilibrium in presence of chemical additives, which operate as inhibitors, promoters, or both together. In the recent years, a very limited number of data collections on hydrate equilibrium has been produced; moreover, these data have not been fully reported in these works, making further research necessary to obtain complete information. We provide a detailed collection of the equilibrium data of hydrate containing single guest as CH₄, C₂H₆, C₃H₈, C₄H₁₀, CO₂, N₂, Xe, Ar and Kr and a brief review of las-scale reactors nowadays used for making research on gas hydrate. These two kinds of information, will be extremely helpful for researchers which are planning to realize a new experimental apparatus for studying gas hydrate. It is well known how, rather than process parameters (i.e. pressure, temperature, presence of a porous medium and its permeability and porosity, presence of impurities, and so on), also specifics of each reactor may strongly intervene on formation results. The second part of this work consists in a collection of the thermodynamic equilibrium data of hydrate in the presence of additives. Some substances are known to be selective inhibitors (promoters); other compounds have greater efficiency when coupled to further chemicals while, in some cases, such coupling can cancel the inhibitory (or promoter) effect. Finally, a state of the art of hydrate equilibrium experiments carried out with methane and carbon dioxide, with a simultaneous presence of inhibitors and promoters, was provided.

本工作着眼于单客水合物相平衡数据，以及在存在化学添加剂的情况下的水合物平衡，化学添加剂既可作为抑制剂，也可作为促进剂，或两者一起起作用。近年来，关于水合物平衡的数据收集数量非常有限。此外，这些数据还没有在这些工作中得到充分报道，因此有必要进行进一步的研究以获得完整的信息。我们提供了包含CH ₄，C ₂ H ₆，C ₃ H ₈，C ₄ H ₁₀，CO ₂，N _2的单个客体的水合物平衡数据的详细收集，Xe，Ar和Kr以及现今用于进行天然气水合物研究的las-scale反应堆的简要回顾。这两种信息对于计划实现一种用于研究天然气水合物的新型实验设备的研究人员将非常有用。众所周知，除了工艺参数（即压力，温度，多孔介质的存在及其渗透性和孔隙率，杂质的存在等）以外，每个反应器的特性也会如何强烈地干预地层结果。这项工作的第二部分包括在添加剂存在下水合物热力学平衡数据的收集。已知某些物质是选择性抑制剂（促进剂）。其他化合物与其他化学物质结合使用时效率更高，在某些情况下，这样的偶联可以消除抑制作用（或启动子）。最后，提供了在同时存在抑制剂和促进剂的情况下，用甲烷和二氧化碳进行的水合物平衡实验的最新技术水平。
