  • Regenerative gas dehydrator
    Patent number: 5664426
    Abstract: The invention disclosed herein relates to a dehydrator for removing moisture from a gas. The dehydrator has a narrow elongate conduit having an equivalent hydraulic diameter which facilitates the diffusion of water molecules through the gas to a cooled gas contact surface of the conduit. Despite the use of narrow elongate gas flow path, the dehydration efficiency of the apparatus of the invention is outstanding and pluggage of the gas flow path is substantially eliminated.
