摘要: The separation of methane from an admixture (110) with ethane and higher hydrocarbons, especially natural gas, using a scrub column (114), in which the is separated into methane-rich overhead (116) that partially condensed (122) to provide reflux (114) liquid methane- depleted bottoms (126), improved by providing additional (136) derived enriched stream (130) fractionation (128) liquid. Preferably, absorber (140) also introduced column. vapor fraction (120) remaining after partial condensation can be liquefied LNG product (124).
