Effectiveness of Odor Counteractants for the Treatment of Stack Gases

Successful control of some contaminant sources is extremely difficult to achieve technically and there remains a need for more information specific to control procedures. The cost of air cleaning equipment installations can be exceedingly high depending upon the performance standards to be satisfied and the physical and chemical characteristics of the contaminants. Control of emissions from the foundry cupola, the steel mill, metal refining operations, coal burning utilities, and incinerators still presents imposing cost and operational and performance problems—despite the technological progress made in recent years. The interrelationship of the source, the degree of control necessary, the equipment available to do the job, and the costs are discussed.
