Abstract
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.
