ABSTRACT:
Many industrial operations generate and release volatile organic compounds. The fumes, frequently mixed with large quantities of air, are collected and sorbed on activated carbon. The spent sorbent is frequently sent to an off-site facility for reactivation since on-site reactivation of the spent sorbent has heretofore been very costly. Shipping of hazardous waste products such as spent sorbents containing sorbed volatile organic compounds on public roads is a growing concern of governmental bodies and regulations requiring on-site handling are anticipated.
This invention provides a closed loop system for on-site reactivation of the spent sorbent and incineration of the contaminants. The combustion gases are cleaned simultaneously with the main gas stream containing the volatile organic compuonds so that only cleaned gases are vented to the atmosphere.
