A natural gas adsorptive separation system and method is described. A method of separating natural gas includes directing a natural gas mixture through an activated carbon adsorption tower until the adsorption tower is saturated, collecting methane from the output of the adsorption tower, heating the saturated carbon adsorption tower with adsorbate using a heater and/or a vacuum pump in a closed loop circuit with the carbon adsorption tower until the input to the vacuum pump is within a specified temperature of the output of the heater, lowering the pressure in the heated activated carbon adsorption tower using the vacuum pump to desorb at least one hydrocarbon compound of the plurality of different hydrocarbon compounds, compressing and cooling the desorbed hydrocarbon compound, separating the cooled and compressed hydrocarbon compound into gas and liquid in a fluid separator, and collecting the liquid from the fluid separator.

Natural gas adsorptive separation system and method

A portable pressure swing adsorption method and system for fuel gas conditioning. A fuel gas conditioning system includes a pressure swing adsorption (PSA) system fluidly coupled to a rich gas stream, the PSA system including a plurality of adsorbent beds and configured to condition the rich natural gas stream and produce therefrom a high-quality fuel gas and gaseous separated heavier hydrocarbons, a product end of the adsorbent beds fluidly coupled to a fuel gas line, wherein the high-quality fuel gas is discharged from the product end and supplied to the fuel gas line, and a feed end of the adsorbent beds configured to be fluidly coupled to the rich natural gas stream or a raw natural gas stream, wherein the produced gaseous separated heavier hydrocarbons are recirculated into the rich natural gas stream or the raw natural gas stream.
