ABSTRACT:
This invention relates to the substantial reduction of emission of noxious gases into the atmosphere. More specifically, this invention relates to a system for saturating mist eliminators in conjunction with the sulfuric acid plant to remove SO.sub.3 gas during an upset condition upstream of the mist eliminators. The system involves the spraying of sulfuric acid onto conventional mist eliminators to substantially saturate the same so that when contact is made with the mist eliminators by the SO.sub.3 gas the same will be absorbed and be removed and will be prevented from being emitted to the atmosphere.
