Regenerative Catalytic Oxidizer (RCO)

RCO combines regenerative oxidization and catalytic oxidization principle. The technology is to lower RTO operating temperature, enhance destruction efficiency and reduce fuel consumption. RCO system is based on RTO’s structure design and adds a layer of special catalytic material in the oxidizer. Catalytic reaction provides enough heat to destruct VOCs and decrease RTO operating temperature. RCO unit design is similar to RTO. Both are designed with two-canister or multi-canister. Every canister is filled with a certain amount of ceramics to substitute heat from the process. Upper chamber connects with the oxidizer chamber and adds a layer of precious metal as catalytic between the heat exchanger chamber and the oxidizer chamber. When VOCs stream enters in RCO system, it is preheated in the heat exchanger and passes through and catalytic bed and then undergoes the oxidization process. After oxidization, the stream leaves the chamber and enters in another heat exchanger zone. VOCs stream undergoes catalytic oxidization and is converted into harmless vapor and CO2 and then discharged into the atmosphere. RCO utilizes regenerative technology, so it just puts few fuels to maintain required reaction temperature. RCO’s destruction efficiency is equal to or above 95% and the heat-recovery is similar to RCO. RCO has two-canister design and three-canister design.
