Process for extracting ethane and heavier hydrocarbons from lng

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