<p>Contemplated systems and methods employ a portion of vaporized and heated LNG as a defrosting medium in an LNG ambient air vaporizer. Most preferably, the LNG is heated to a temperature of about 100° F. to 400° F., and is after defrosting fed back to the LNG stream at a position that is upstream and/or downstream of the vaporizer or to the natural gas delivery pipeline.</p> |
