【 摘 要 】

Organic solvents with different volatilities are widely used in various processes and generate air and water pollution problems. One of the popular treatment processes for volatile organic compounds (VOCs) is regenerative thermal oxidation for the high destruction and removal efficiency. In this paper, the authors presents a project case dealing with VOCs, the waste gas with triethylamine and N-butylamine is disposed by a three-bed RTO treatment process. Two novel strategies were used in this project compared with the conventional RTO systems. Firstly, heat storage materials are saddle-shaped honeycomb, which could reform the distribution of waste gas flow in the saddle area and improve the efficiency of heat exchange. Secondly, the control mode of quick-opening valve is exhaust temperature control method instead of the time interval. The operation data shows that more than 99% of destruction and removal efficiency of VOC is obtained with slightly-level natural gas consumption. This research could provide a practical basis for the design of a RTO system.
