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. |
