Abstract

A system and method scrub a vapor. In one embodiment, a vacuum truck scrubber system includes a liquid vat. The liquid vat comprises liquid. The system also includes a first carbon canister. The liquid vat is connected to the first carbon canister. The first carbon canister contains carbon. In addition, the system includes a second carbon canister. The first carbon canister is connected to the second carbon canister. The second carbon canister contains carbon. In addition, the system includes a third carbon canister. Moreover, the system includes that a vapor comprising contaminants is fed to the liquid vat and is introduced from the liquid vat to the first carbon canister wherein a portion of the contaminants are removed from the vapor. The vapor is introduced from the first carbon canister to the second carbon canister wherein another portion of the contaminants are removed from the vapor.

Claims

1. A vacuum truck scrubber system, comprising:

a liquid vat, wherein the liquid vat comprises liquid;

a first carbon canister, wherein the liquid vat is connected to the first carbon canister, and wherein the first carbon canister contains carbon;

a second carbon canister, wherein the first carbon canister is connected to the second carbon canister, and wherein the second carbon canister contains carbon; and

a third carbon canister, wherein a vapor comprising contaminants is fed to the liquid vat and is introduced from the liquid vat to the first carbon canister wherein a portion of the contaminants are removed from the vapor, and wherein the vapor is introduced from the first carbon canister to the second carbon canister wherein another portion of the contaminants are removed from the vapor.

2. The vacuum truck scrubber system of claim 1, wherein the first carbon canister, the second carbon canister, and the third carbon canister are disposed in a substantially triangular configuration.

3. The vacuum truck scrubber system of claim 1, wherein the first carbon canister is connected to the liquid vat by a canister feed, and wherein the first carbon canister is connected to the second carbon canister by a second canister feed.

4. The vacuum truck scrubber system of claim 1, wherein the first carbon canister, the second carbon canister, and the third carbon canister each comprise a carbon removal means.

5. The vacuum truck scrubber system of claim 1, further comprising a monitoring system.

6. The vacuum truck scrubber system of claim 5, wherein the monitoring system comprises a monitor, a transmitter, a portable station, and a viewing station.

7. The vacuum truck scrubber system of claim 1, wherein the liquid vat is disconnected from the first carbon canister when a criteria is achieved.

8. The vacuum truck scrubber system of claim 7, wherein the liquid vat is connected to the second carbon canister, and wherein the second carbon canister is connected to the third carbon canister.

9. The vacuum truck, scrubber system of claim 1, wherein the liquid vat, the first carbon canister, the second carbon canister, and the third carbon canister are disposed on a trailer.

10. The vacuum truck scrubber system of claim 9, wherein the trailer comprises placement guides.

11. A method for scrubbing contaminants from a vapor, wherein the vapor comprises the contaminants, comprising:

(A) feeding a vapor to a liquid vat;

(B) introducing the vapor from the liquid vat to a first carbon canister, wherein the liquid vat is connected to the first carbon canister;

(C) removing a portion of the contaminants from the vapor in the first carbon canister;

(D) introducing the vapor from the first carbon canister to a second carbon canister, wherein the first carbon canister is connected to the second carbon canister;

(F) removing another portion of the contaminants from the vapor in the second carbon canister; and

(F) providing a third carbon canister, wherein the third carbon canister comprises a reserve carbon canister.

12. The method of claim 11, wherein the first carbon canister, the second carbon canister, and the third carbon canister are disposed in a substantially triangular configuration.

13. The method of claim 11, wherein the first carbon canister contains carbon, and wherein the second carbon canister contains carbon.

14. The method of claim 11, further comprising monitoring the first carbon canister to determine when a criteria is achieved.

15. The method of claim 14, when the criteria is achieved, further comprising disconnecting the liquid vat from the first carbon canister, and disconnecting the first carbon canister from the second carbon canister, and connecting the liquid vat to the second carbon canister, and connecting the second carbon canister to the third carbon canister.

16. The method of claim 15, further comprising introducing the vapor from the liquid vat to the second carbon canister, and further comprising removing a portion of the contaminants from the vapor in the second carbon canister.

17. The method of claim 16, further comprising introducing the vapor from the second carbon canister to the third carbon canister, and further comprising removing another portion of the contaminants from the vapor in the third carbon canister.

18. The method of claim 15, wherein the first carbon canister contains carbon, and further comprising removing the carbon from the first carbon canister.

19. The method of claim 11, wherein the third carbon canister is not connected to the first carbon canister or the second carbon canister.

20. The method of claim 11, wherein the liquid vat contains a water-based oxidizer.
