Abstract
A system is provided for controlling volatile organic compound emissions from rotating and reciprocating mechanical equipment. The system comprises a vapor flow, a combustor, and a device for preventing combustion of the volatile organic compound within the system.
Claims10
A collection system for controlling fugitive organic compound vapor emissions from a pump comprising:
- a. vapor flow means for drawing sufficient air into a seal region of said pump to dilute an organic compound vapor located therein to a concentration below the lower explosion limit of said organic compound vapor, and for withdrawing an air/organic compound vapor mixture from said seal region;
- b. a combustion means in fluid communication with said vapor flow means for disposal of said air/organic compound vapor mixture;
- and
- c. a flow control means in fluid communication with both said seal region and said vapor flow means for preventing combustion of said air/organic compound vapor mixture within said collection system.
