Title:
SEPARATION OF C2+ PARAFFINS FROM METHANE USING REGENERABLE MACROPOROUS ALKYLENE-BRIDGED ADSORBENT IN A PACKED MOVING BED WITH MICROWAVE REGENERATION
Document Type and Number:
WIPO Patent Application WO/2016/122843
Kind Code:
A3
Abstract:
A method for separating natural gas liquids (NGLs) from a hydrocarbon gas mixture containing natural gas liquids and methane, comprising the steps of: i) providing a bed of adsorbent selective for NGLs over methane; ii) passing a hydrocarbon gas mixture containing methane and NGL through the bed of adsorbent to at least partially remove NGLs from the gas mixture to produce: (a) NGL-loaded adsorbent and (b) NGL-depleted hydrocarbon gas mixture; iii) recovering the NGL-depleted hydrocarbon gas mixture; iv) regenerating the NGL-loaded adsorbent by at least partially removing NGLs from the adsorbent; and v) sequentially repeating steps (ii) and (iii) using regenerated adsorbent from step (iv).
