Abstract
A mobile regeneration apparatus is provided for regenerating dryers. The regeneration apparatus may be used to regenerate single tower desiccant dryers located at natural gas vehicle refueling stations. For optimum performance, each dryer may be located upstream of a respective compressor.
Claims20
A method of handling gas, said method comprising the steps of:
- flowing a first gas through a first adsorbent dryer, using said dryer to dry said first gas, and subsequently compressing said first gas into a first storage vessel;
- flowing a second gas through a second adsorbent dryer, using said second adsorbent dryer to dry said second gas, and subsequently compressing said second gas into a second storage vessel, said second dryer being remote from said first dryer;
- and
- using a mobile regeneration apparatus to regenerate said first and second dryers.

A mobile regeneration apparatus for regenerating an adsorbent dryer, said apparatus comprising:
- a conduit system for connecting said apparatus to the adsorbent dryer;
- a blower for causing regenerating fluid to flow through the adsorbent dryer;
- a heater for heating the regenerating fluid, said heater being connected to said blower by said conduit system;
- a cooler for cooling the regenerating fluid, said cooler being connected to said heater by said conduit system;
- and
- a separator for removing water from the regenerating fluid, said separator being located between said cooler and said heater, said separator being connected to said heater and said cooler by said conduit system.

A system for refueling natural gas vehicles, said system comprising:
- a first refueling station including a storage vessel, a compressor for compressing natural gas into said storage vessel, and an adsorbent dryer for drying the natural gas, said compressor being located between said adsorbent dryer and said storage vessel, said storage vessel being connected to said compressor by a first conduit, said compressor being connected to said dryer by a second conduit;
- a second refueling station including a storage vessel, an adsorbent dryer, and a compressor, said second refueling station being remote from said first refueling station, said storage vessel of said second refueling station being connected to said compressor of said second refueling station by a third conduit, said compressor of said second refueling station being connected to said adsorbent dryer of said second refueling station by a fourth conduit;
- and
- a mobile regeneration apparatus for regenerating said adsorbent dryers.
