Separate NOx, particulates, and SOx removal systems are required for controlling the emission from the stationary source such as power plants and cogeneration systems. Although the electrostatic precipitator and SOx removal systems are highly efficient, NOx removal system has problems associated with removal efficiency and operating cost. For the purpose of development of the innovative technology, high efficient NOx, SOx and particulates simultaneous removal system was explored using the single-stage, plasma-chemical hybrid system with the use of real diesel engine emission and operating temperature. The system was evaluated in rms of removal efficiency for each constituent, power consumption, byproducts identification, optimization, and economic analysis. Based on data obtained from the previous reseach, we selected the pulse power supply for the plasma generation combined with the chemical reactor to obtain the engineering evaluation toward designing a full-scale plasma-chemical hybrid system. As a result, more than 75% of NOx, 93% of SOx, and 88% of low resistive and difficult to collect fine particulates were obtained. Byproducts such as CO and N_2O were with less than 10 ppm. The operating cost of NOx alone is less than 1/4 of the commercially available selective catalytic reduction (SCR) system, which is approximately $4,200/ton of NO for the plasma-chemical hybrid system as opposed to $12,000/ton of NO for the SCR process. In addition, particulates and SOx removal systems can be eliminated which leads to more significant cost induction.

需要单独的NOX，微粒和SOX去除系统来控制固定源的发射，例如发电厂和加电系统。尽管静电排气器和SOX去除系统效率高，但NOX去除系统与去除效率和运营成本有关。为了开发创新技术，使用单级，等离子体化学混合系统探索了高效的NOX，SOX和颗粒系统，并使用真实的柴油发动机发射温度和工作温度。该系统以每个组成，功耗，副产品识别，优化和经济分析的删除效率RMS进行评估。基于从先前的研究中获得的数据，我们选择了等离子体产生的脉冲电源与化学反应器相结合，以获得工程评估，以设计全尺度的等离子体化学混合动力系统。结果，获得了超过75％的NOX，93％的Sox和88％的低电阻和难以收集细微粒。 CO和N_2O等副产品的少于10 ppm。仅NOX的运营成本少于市售选择性催化减少（SCR）系统的1/4，对于等离子化学混合动力系统的价格约为$ 4,200/吨，而SCR则为$ 12,000/吨。过程。此外，可以消除颗粒物和SOX去除系统，从而导致更明显的成本诱导。
