Abstract

A system and method scrub a vapor. In embodiments, a vacuum truck scrubber system includes a liquid vat, a first carbon canister, a second carbon canister, and a third carbon canister. The first carbon canister and the second carbon canister each contain carbon. The liquid vat is connected to the first carbon canister. The first carbon canister is connected to the second carbon canister. A vapor having 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 is removed from the vapor. The vapor is introduced from the first carbon canister to the second carbon canister wherein another portion of the contaminants is removed. The vacuum truck scrubber system also includes a monitoring system for reading and recording of sample measurements in the first carbon canister, the second carbon canister and the third carbon canister.

Claims

1. A vacuum truck scrubber system, comprising:

a liquid vat, wherein a liquid is disposed in the liquid vat;

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;

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 is 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 is removed from the vapor; and

a monitoring system, wherein the monitoring system provides for reading and recording of sample measurements in the first carbon canister, the second carbon canister and the third carbon canister.

2. The vacuum truck scrubber system of claim 1, wherein the monitoring system comprises a transmitter disposed on the first carbon canister, a second transmitter disposed on the second carbon canister, and a third transmitter disposed on the third carbon canister.

3. The vacuum truck scrubber system of claim 2, wherein the transmitter comprises a sensor, the second transmitter comprises a second sensor, and the third transmitter comprises a third sensor.

4. The vacuum truck scrubber system of claim 3, wherein the sensor measures a first carbon canister vapor content, the second sensor measures a second carbon canister vapor content, and the third sensor measures a third carbon canister vapor content.

5. The vacuum truck scrubber system of claim 2, wherein the monitoring system further comprises a monitor.

6. The vacuum truck scrubber system of claim 5, wherein the transmitter, the second transmitter, and the third transmitter transmit signals to the monitor.

7. The vacuum truck scrubber system of claim 1, wherein the monitoring system measures vapor content.

8. The vacuum truck scrubber system of claim 7, wherein the vapor content comprises volatile organic compound levels in the vapor.

9. The vacuum truck scrubber system of claim 1, wherein the monitoring system comprises a transmitter disposed on the liquid vat.

10. The vacuum truck scrubber system of claim 1, wherein the monitoring system provides an alarm when a criteria is achieved.

11. A vacuum truck scrubber system, comprising:

a liquid vat, wherein a liquid is disposed in the liquid vat;

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

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 further wherein the second carbon canister comprises a second canister sparger; and

a third carbon canister, wherein the third carbon canister comprises a third canister sparger, and 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 is 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 is removed from the vapor.

12. The vacuum truck scrubber system of claim 11, wherein the third carbon canister comprises carbon.

13. The vacuum truck scrubber system of claim 12, wherein the first canister sparger, the second canister sparger, and the third canister sparger are disposed in carbon.

14. The vacuum truck scrubber system of claim 11, wherein the first canister sparger, the second canister sparger, and the third canister sparger each comprise a canister sparger body and canister sparger arms.

15. The vacuum truck scrubber system of claim 14, wherein the canister sparger alms extend from the canister sparger body.

16. The vacuum truck scrubber system of claim 14, wherein the canister sparger arms have openings through which the vapor flows from the canister sparger body.

17. The vacuum truck scrubber system of claim 16, wherein the openings are disposed on a side of the canister sparger arms.

18. The vacuum truck scrubber system of claim 16, wherein the openings are not disposed on a top side of the canister sparger arms.

19. The vacuum truck scrubber system of claim 11, wherein the first canister sparger, the second canister sparger, and the third canister sparger each have a valve.

20. The vacuum truck scrubber system of claim 19, wherein the first carbon canister, the second carbon canister, and the third carbon canister each have a canister feed, and wherein the valve of each of the first canister sparger, the second canister sparger, and the third canister sparger is disposed at about a connection of the canister feed.
