Abstract

The presently disclosed concepts relate to systems and methods for effluent stream abatement via pyrolytic emission looping. In use, the systems and methods include a feed gas stream, and at least one dissociating reactor that receives the feed gas stream. The at least one dissociating reactor outputs, at least in part, a carbon allotrope material and a discharge pyrolytic emissions stream. Additionally, a gas separating system is used to separate the discharge pyrolytic emissions stream into at least one species component, where the at least one species component is added to at least the feed gas stream.

First claim

What is claimed is:

1. A method, comprising:
receiving pyrolytic emissions from a first dissociating reactor, wherein the first dissociating reactor is configured to dissociate hydrocarbons and form at least a first carbon allotrope material;
separating the pyrolytic emissions into at least one species component;
adding the at least one species component as feed gas to be provided to at least a second dissociating reactor, wherein the second dissociating reactor is configured to process refined pyrolytic effluent from the first dissociating reactor and form a second carbon allotrope material different from the first carbon allotrope material; and
receiving at least in part the at least one species component from a third dissociating reactor, wherein the third dissociating reactor is configured to dissociate the hydrocarbons and form at least a third carbon allotrope material different from each of the first carbon allotrope material and the second carbon allotrope material.

2. The method of claim 1 , wherein the pyrolytic emissions include emission byproducts.

3. The method of claim 1 , wherein the pyrolytic emissions include molecularly decomposed hydrocarbons.

4. The method of claim 1 , wherein the pyrolytic emissions include a thermal decomposition.

5. The method of claim 4 , wherein the thermal decomposition occurs in the absence of oxygen.

6. The method of claim 4 , wherein the thermal decomposition includes a decomposition of at least one hydrocarbon.

7. The method of claim 1 , wherein the second dissociating reactor includes one or more hydrocarbon designed reactors, wherein the one or more hydrocarbon designed reactors are configured to form a predetermined carbon material allotrope.

8. The method of claim 1 , wherein the at least one species component is further added to a feed gas stream to the first dissociating reactor.

9. The method of claim 1 , wherein the at least one species component includes at least one of Ar, N 2 , H 2 , CH 4 , O 2 , or CO 2 .

10. The method of claim 1 , wherein a second portion of the at least one species component is an input stream to at least one of:
a proton exchange membrane fuel cell,
the first dissociating reactor;
the third dissociating reactor,
a power generation turbine,
a catalytic converter,
an oxidizer, or
a CO 2 cracker.

11. The method of claim 1 , wherein at least one of the first dissociating reactor or the second dissociating reactor is configured for a hydrocarbon site, wherein the hydrocarbon site includes at least one of oil field, gas field, oil sand, oil shale deposit, coal deposit, offshore oil reserve, offshore gas reserve, shale gas deposit, methane hydrates, oil seep, or gas seep.

12. The method of claim 1 , wherein at least one of the first dissociating reactor or the second dissociating reactor is configured for a remote hydrocarbon site, and at least one of the following provisos are satisfied:
wherein the separation into at least one species component at the remote hydrocarbon site is configured for hydrocarbon reduction,
wherein the separation into at least one species component at the remote hydrocarbon site is configured for hydrocarbon abatement, or
wherein the separation into at least one species component reduces discharge of greenhouse gases.

13. The method of claim 1 , wherein at least one of the first dissociating reactor or the second dissociating reactor includes a thermal reactor.

14. The method of claim 1 , wherein at least one of the first dissociating reactor or the second dissociating reactor includes a microwave reactor.

15. The method of claim 1 , wherein all of the at least one species component is reused by one or more of the first dissociating reactor, the second dissociating reactor, or a third dissociating reactor.

16. The method of claim 1 , wherein at least one of the at least one species component is reused by at least one of the first dissociating reactor, or the second dissociating reactor.

17. The method of claim 1 , wherein the first carbon allotrope material comprises hot carbon, and the second carbon allotrope material comprises carbon oxides.

18. The method of claim 1 , wherein the first dissociating reactor and the second dissociating reactor are configured to form predetermined carbon material allotropes.

19. The method of claim 1 , wherein the pyrolytic emissions comprise molecularly decomposed hydrocarbons from thermal decomposition occurring in the absence of oxygen.

20. The method of claim 1 , wherein the at least one species component comprises H2 and is provided as an input stream to a power generation turbine.
