NG-SV-FM is an ideal system for drying small volumes of natural gas for stations with intermittent use. Each unit is conservatively sized to remove moisture from gas upstream of the natural gas compressor.
The dryer is shipped with an initial charge of molecular sieve desiccant. Prior to installing shipping plugs, the bed is blanketed with bone dry nitrogen gas. The nitrogen blanket keeps the bed fresh and allows long term storage of the dryer prior to installation.
When the initial charge of desiccant has reached maximum drying capacity, it can be replaced with a fresh charge of desiccant.
