Comparing Fuel Costs of Regenerative Catalytic Oxidizers versus Regenerative Thermal Oxidizers

RTO (Ceramic Bed) vs an HTT RCO (A-A Exchanger catalytic)

The emission control industry appears to have created a stream of misinformation and untruths concerning the fuel cost comparison between RTO and RCO systems. Simply put, they do not tell customers that natural gas at 1600oF has half the heat value than it does at 70oF. Customers pay for FT3 of natural gas, not BTUs. So when suppliers calculate a 1,000,000 BTU operating cost it is really a 2,000,000 BTU operating cost.

An HTT RCO uses an Air to Air preheat exchanger and a precious metal catalyst bed, allowing oxidation to occur at approximately 550-600oF. This lower temperature requirement reduces the amount of natural gas needed to fuel the VOC abatement system and the overall size of the incinerator. Catalysts typically used for VOC incineration include platinum and palladium.

Below is a detailed cost comparison between RCOs and RTOs for download.
