The regenerative thermal oxidizer (RTO) is a very durable, well-proven technology suitable for treating a wide variety of emission streams; however, the RTO may not be the most economical technology available. Two very common systems for treating emissions from coating and finishing processes are the RTO and the concentrator/oxidizer system. To determine which system is best suited for a given application, the capabilities and life-cycle costs of each must be evaluated and compared. Below is a summary of the RTO and the concentrator/oxidizer system, how each operates, how their characteristics affect both plant operation and lifecycle costs, and details on actual life-cycle costs and performance data.
