Disclosed is a method for running natural gas powered stationary combustion systems, such as an internal combustion engine, a furnace, a fired heater, a power plant, an incinerator, and the like. In one embodiment of the present method, ethane and heavier hydrocarbons or propane and heavier hydrocarbons (29) are removed (90) from a natural gas feedstream (3) to provide the methane-rich natural gas stream (5) used to fuel the stationary combustion system (100). One embodiment of this method provides for the use of a regenerable adsorbent media to remove the higher hydrocarbons which is regenerated by a microwave heating system. Said regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process.

1. A method to run a stationary combustion system fueled by a methane-rich natural gas supply wherein the methane-rich natural gas supply is derived from a natural gas feedstream comprising methane and one or more of the natural gas liquids (NGLs): ethane, propane, butane, pentane, or heavier hydrocarbons, wherein some or all of the NGLs are separated from the natural gas feedstream by means of a NGLs separation unit to provide the methane-rich natural gas supply, wherein the NGLs separation unit comprises: (i) an adsorption unit comprising an adsorption bed comprising an adsorbent media consisting of a porous cross-linked polymeric adsorbent, a pyrolized macroporous polymer, or mixtures thereof which adsorbs NGLs to form a loaded adsorbent mediaand(ii) a regeneration unit comprising a means to regenerate loaded adsorbent media by causing the release of adsorbed NGLs from the loaded adsorbing media and forming regenerated adsorbent mediawherein the method comprises the steps of: (a) passing the natural gas feedstream through the adsorption unit generating the adsorbent loaded with NGLs and a methane-rich natural gas supply,(b) transporting the adsorbent loaded with NGLs from the adsorption unit to the regeneration unit,(c) regenerating the adsorbent loaded with NGLs by releasing the adsorbed NGLs from the loaded adsorbing media and forming regenerated adsorbent media(d) transporting the regenerated adsorbent media back to the adsorption unit for reuse,(e) discharging the released NGLs to be recovered, re-injected, or flared, and(f) using the methane-rich natural gas supply to fuel the combustion system. 2. The method of claim 1 wherein the loaded adsorption media is regenerated by means of reduced pressure over the media, heating the media, or a combination of reduced pressure and heating. 3. The method of claim 1 wherein the loaded adsorption media is regenerated by a microwave heating system. 4. The method of claim 1 wherein the regeneration step is operated as a batch process, a semi-continuous process, or as a continuous process. 5. The method of claim 1 wherein the stationary combustion system is a stationary internal combustion engine, a furnace, a fired heater, a power plant, or an incinerator and the natural gas feedstream is from an oil well, a gas well, a condensate well, or a natural gas pipeline. 6. The method of claim 1 wherein the stationary combustion system is an internal combustion engine used to power onsite equipment used for oilfield operations and/or to power equipment used to maintain and operate natural gas pipelines wherein the source of the natural gas feedstream is from an oil well, a gas well, or a condensate well.
