In this study, optimization of MEK and Toluene removal was conducted by HTO(Hybrid Thermal Oxidation) system. HTO system has a multi-bed reaction plate and the plate consisted of wasted heat regeneration part and catalysis part. VOCs removal by HTO system was estimated by changing inlet flow rates with different valve changing times. Under $350^{\circ}C$ of combustion temperature, VOCs was fully converted and the equivalent conversion was 100%. The thermal oxidation efficiency, related to the amount of injected fuel into HTO system and the valve change time, was revealed at the level of 93.0~96.3%. In case of MEK removal by HTO system, the efficiency was ranged from 91.1 to 97.1%. Also, Toluene removal efficiency(93.2~97.4%) was good and stable with respect to the operating conditions. Considering above results, it was proved that HTO system could be a stable and compact system for VOCs, especially MEK and Toluene with high removal efficiency.
