Natural gas and biogas are two mixtures that consist of methane as their main component. These two gas mixtures are usually saturated with water vapor, which cause many problems, such as damaging the gas processing equipment by increasing the gas’s corrosion potential or clogging the pipelines due to gas hydrate formation. Thus, removing water vapor from these gas streams is mandatory. In this review paper, the main dehydration methods have been overviewed, and scrutiny of the adsorption dehydration has been carried out. Furthermore, the most important solid desiccants and their improvements have been reviewed.

使用固体干燥剂对天然气和沼气流进行脱水：综述

天然气和沼气是两种以甲烷为主要成分的混合物。这两种气体混合物通常被水蒸气饱和，这会导致许多问题，例如通过增加气体的腐蚀潜力来损坏气体处理设备或由于形成气体水合物而堵塞管道。因此，必须从这些气流中去除水蒸气。在这篇综述论文中，概述了主要的脱水方法，并对吸附脱水进行了审查。此外，还审查了最重要的固体干燥剂及其改进。
