1. A method of removing C5+ hydrocarbons from a natural gas feed gas (FG) stream and sending to a natural gas liquids (NGL) recovery or liquefied natural gas (LNG) facility or a CO2 removal processing unit and/or a pipeline, the method comprising:
routing the FG at a pressure Padsorber over an adsorber to adsorb C5+ hydrocarbon and provide a heavy hydrocarbon depleted natural gas (HHCDNG) stream at pressure Padsorber ranging from about 300 psia to about 1200 psia, wherein the adsorber comprises a hydrocarbon-selective adsorbent; and
routing the HHCDNG stream through one or more compressors to provide a HHCDNG at pressure P3, wherein P3>Padsorber, and wherein the adsorbent is configured to operate at the pressure Padsorber associated with increased adsorption capacity and/or longer breakthrough time of the C5+ hydrocarbons.
