Abstract:
A method of dehydrating a hydrocarbon gas stream including stripping water from a liquid desiccant stream using a water-undersaturated portion of the gas stream, drying the gas stream to extract the stripped water, and then further drying the partially-dried gas stream using the stripped desiccant to achieve a low water content level in the gas stream for pipeline transportation. In one embodiment, the liquid desiccant is supplied by a regeneration facility at a remote location and the liquid desiccant is returned to the regeneration facility for regeneration after drying the gas. In another embodiment, the regeneration of the desiccant is performed locally whereby the liquid desiccant is, after drying the gas, stripped again of water and reused locally.
