Adsorbed natural gas storage facility

1. A method of using a natural gas storage facility to reduce the effect of diurnal demand on a natural gas source, the method comprising:

introducing a natural gas into the natural gas storage facility during a non-peak period of demand, such that the introduced natural gas does not form either hydrocarbon liquids or non-hydrocarbon liquids at operating conditions of the natural gas storage facility, and such that condensation and vaporization are avoided in the natural gas storage facility;

operating the natural gas storage facility during the non-peak period of demand such that

a guard bed system removes a natural gas impurity from the introduced natural gas, selectively separates the introduced natural gas into a heavy natural gas component and a light natural gas component, and retains the heavy natural gas component during the non-peak period of demand,

the light natural gas component passes from the guard bed system into an adsorbent bed system, and

the adsorbent bed system adsorbs the light natural gas component into a light natural gas adsorbent and retains the light natural gas component during the non-peak period of demand;

operating the natural gas storage facility during a period of peak demand such that

the guard bed system releases the heavy natural gas component,

the adsorbent bed system releases the light natural gas component from the light natural gas adsorbent, and

the released heavy natural gas component and the released light natural gas component mix to form a released natural gas product having a first temperature; and

introducing the released natural gas product into the natural gas source during the peak period of demand;

where the natural gas storage facility comprises the adsorption bed system that fluidly couples to the guard bed system,

where the natural gas source contains the natural gas, and

where the natural gas includes the impurity, the light natural gas component and the heavy natural gas component, and is flowing at a second temperature.

2. The method of claim 1 where the guard bed system includes a heavy natural gas adsorbent and is operable to retain the heavy natural gas component by adsorption.

3. The method of claim 2 where the heavy natural gas adsorbent is a microporous material.

4. The method of claim 1 where the light natural gas component is substantially free of propane.

5. The method of claim 4 where the light natural gas component is substantially free of ethane.

6. The method of claim 1 further comprising:

operating a temperature control system during the non-peak period of demand such that heat is removed from the guard bed system; and

operating the temperature control system during the peak period of demand such that heat is introduced into the guard bed system;

where the natural gas storage facility further comprises the temperature control system that is coupled to the guard bed system.

7. The method of claim 1 further comprising:

operating a temperature control system during the non-peak period of demand such that heat is removed from the light natural gas adsorbent; and

operating the temperature controls system during the peak period of demand such that heat is introduced into the light natural gas adsorbent;

where the natural gas storage facility further comprises the temperature control system that is coupled to the adsorption bed system.

8. The method of claim 1 further comprising operating a storage facility compressor during the introduction of the natural gas into the natural gas storage facility, where the natural gas storage facility further comprises the storage facility compressor that is coupled to the guard bed system.

9. The method of claim 1 further comprising operating a storage facility compressor during the period of peak demand such that a less than atmospheric condition forms in the guard bed system, where the natural gas storage facility further comprises the storage facility compressor that is coupled to the guard bed system.

10. The method of claim 1 further comprising operating a storage compressor during the period of peak demand such that a less than atmospheric pressure condition forms in the adsorbent bed system, where the natural gas storage facility further comprises the storage facility compressor that is coupled to the adsorbent bed system.

11. The method of claim 1 further comprising operating the natural gas storage facility during the period of peak demand such that the released light natural gas component assists in releasing the heavy natural gas component, forming the released natural gas product in the guard bed system, where the guard bed system fluidly couples to the adsorption bed system such that at least a portion of the released light natural gas component passes into the guard bed system.

12. The method of claim 1 further comprising:

detecting a first condition associated with the start of the non-peak period of demand;

detecting a second condition associated with the end of the non-peak period of demand;

detecting a third condition associated with the start of the peak period of demand;

detecting a fourth condition associated with the end of the peak period of demand;

where detecting the first condition occurs before the introduction of the natural gas into the natural gas storage facility,

where detecting the second condition occurs during the operation of the natural gas storage facility during the non-peak period of demand,

where detecting the third condition occurs before the operation of the natural gas storage facility during the period of peak demand, and

where detecting the fourth condition occurs during the introduction of the released natural gas product into the natural gas source.

13. The method of claim 12 where the second condition and the third condition are the same.

14. The method of claim 12 where the first condition and the fourth condition are the same.

15. The method of claim 12 where all of the conditions are associated with the pressure of the natural gas source.
