A process for the extraction and recovery of ethane and heavier hydrocarbons (C2+) from LNG. The process covered by this patent maximizes the utilization of the beneficial cryogenic thermal properties of the LNG to exact and recover C2+ from the LNG using a unique arrangement of heat exchange equipment a cryogenic fractionation column and processing parameters that essentially eliminates (or greatly reduces) the need for gas compression equipment minimizing capital cost, fuel consumption and electrical power requirements. This invention may be used for one or more of the following purposes: to condition LNG so Oral send-out gas delivered from an LNG receiving and registration terminal meets commercial gas quality specification ; to condition LNG to make Lean LNG that meets fuel quality specification and standards required by LNG powered vehicle and other LNG fueled equipment to condition LNG to make Lean LNG so that it can be used to make CNG meeting specification and standards for commercial CNG fuel; to recover ethane. propane and/or other hydrocarbons heavier then methane from LNG for revenue enhancement , profit or other commercial reasons.
