ABSTRACT:
A process and apparatus for dehydrating natural gas while filling a compressed natural gas storage vessel are provided. The natural gas is dehydrated through a process of compression, followed by expansion for cooling, and freezing or condensation of water from the cooled gas onto the surface of a moisture collecting material. The invention provides dehydrated compressed natural gas which can be used to supply natural gas vehicle filling stations.
