1. A natural gas separation system, comprising:
a plurality of adsorbent towers coupled to at least one first valve, the at least one first valve directing a natural gas inlet flow through one of:
a first adsorbent tower of the plurality of adsorbent towers, when the at least one first valve is in a first position; or
a second adsorbent tower of the plurality of adsorbent towers, when the at least one first valve in a second position;
the first position further coupling the second adsorbent tower to a closed-loop circuit comprising a differential pressure pump and a heater;
the first position further coupling the second adsorbent tower to a desorption circuit; and
at least one second valve that selects between the closed-loop circuit and the desorption circuit in the first position;
wherein in the first position:
at least a portion of light hydrocarbons exits the first adsorbent tower through an outlet; and
natural gas liquids exit the desorption circuit when the desorption circuit is selected.
