Development Trend of Regenerative Thermal Oxidizer(RTO)
[Purposes]RTO is a popular technology for the terminal treatment of Volatile Organic Com-pounds(VOCs),and there is still much room for improvement in terms of energy conservation and safety.By analyzing its research status,engineering applications,and problems faced in actual projects,this paper explores its role and development direction in reducing carbon emissions.[Methods]The principle of using the RTO for the terminal treatment of volatile organic compounds was introduced.Through the investigation and analysis of domestic and foreign experimental studies and engineering cases,the appli-cation of RTO in the pharmaceutical industry was summarized,and the common problems in the opera-tion of RTO were analyzed.[Findings]The thermal efficiency of RTO in the pharmaceutical industry can all be maintained above 93%,and the purification efficiency mostly exceeds 95%.However,RTOs with a long operating life have serious corrosion.At the same time,common problems such as secondary pollution of dioxins,blockage,and over-limit of mixed gases are widespread in RTOs in the pharmaceuti-cal industry.[Conclusions]In the future,in-depth research should be carried out in three aspects:im-proving the oxidation efficiency and energy utilization of RTO,analyzing the combined RTO technology processes in different industries,and further integrating emerging technologies such as artificial intelli-gence,in order to significantly reduce VOCs emissions and contribute to achieving the"dual carbon"goals.
