What is the purpose of a dry bed desiccant in an LNG plant?

The purpose of a dry bed desiccant in an LNG plant is to remove water vapor from process streams to prevent hydrate formation and corrosion, particularly at cryogenic temperatures. These desiccants, typically solid materials like molecular sieves or silica gel, have a high affinity for water molecules. The process stream passes through a vessel containing the desiccant, and water molecules are adsorbed onto the desiccant material. Th....
