Abstract: This paper introduces the sources, emission standards, hazards, safety risks of industrial carbon monoxide (CO) waste gas and uses of CO gas. Combining with the basic structure and working principles of regenerative thermal oxidizer (RTO) and the application practice of CO exhaust gas treatment in a catalyst production plant, it elaborates the method of introducing CO exhaust gas into RTO as supplementary fuel gas to incinerate and treat organic waste gas from other plants, which provides a new idea for the treatment and discharge of CO waste gas up to standard. In addition, the paper also discusses the safety measures for treating CO waste gas by RTO equipment. The successful application of these safety measures can provide reference for the safe and stable operation of the RTO equipment and is worth popularizing in petrochemical industry. Finally, some suggestions are put forward for the development of CO waste gas treatment technology.
