NOVELTY - Recovery of less volatile components from methane-rich gas to a natural gas liquid (NGL) product while producing LNG from more volatile components, involves feeding recovery column for separation into gas and liquid stream. The liquid stream is fed into purifying column to produce NGL product stream and gas stream that is cooled and then introduced to top of NGL recovery column to enhance recovery of desirable less volatile components.    USE - For high recovery of hydrocarbon liquids, such as ethane, propane and propylene, from methane-rich natural gases, such as refinery gases.    ADVANTAGE - For use as quality methane, heavier hydrocarbons should be removed, which also prevents freezing and plugging of equipment. Recovery of the NGL components is maximized to enhance revenue, since they can be used as refinery or petrochemical feedstock. The gas from the NGL recovery plant is delivered to LNG plant. The novel process improves economics by integrating these two stages and increasing the current 80% process efficiency to more than 95% of ethane and heavier hydrocarbons. A significant amount of refrigeration energy is required to liquefy natural gas. However, this process uses a refrigeration stream from the LNG plant.    DETAILED DESCRIPTION - Recovery of less volatile components from methane-rich gas fed under pressure to a natural gas liquid (NGL) product while rejecting more volatile components, subsequently liquefied to produce LNG involves cooling at least some of the gas in one or more heat exchangers using a mechanical refrigeration cycle. The feed is introduced into an NGL recovery column (50) at one or more stages for separation into gas stream of more volatile components, and liquid stream of less volatile components. The liquid stream is fed into NGL purifying column (70) at at least one stage to produce NGL product stream comprising desired less volatile components from the bottom and a second gas stream comprising more volatile components from overhead of the purification column. The second gas stream is cooled and then introduced to top of NGL recovery column as overhead reflux to enhance recovery of desirable less volatile components.    An INDEPENDENT CLAIM is included for an apparatus for use in the above method, comprising heat exchanger to cool part of gas feed, NGL recovery and purification columns, second heat exchanger to cool second gas stream, gas introducer for top of recovery column, and gas liquefier to produced pressurized LNG stream.
