Abstract: Selective Catalytic Reduction (SCR) system provides an effective approach to removing NOx emission, in order to meet stringent emission legislation of NOx generated by internal combustion engine. However, the oversize SCR system would increase its operation costs and occupy more space, which restricts its widespread application to a certain extent. Therefore, the compact structure design of SCR system is worthy of research considering the limited installation space. In the present study, one-dimensional SCR model is established, and the effect of structural parameters on the SCR performance has been investigated by AVL BOOST. Then, based on the Response Surface Methodology (RSM), the coupling relationship among these structural parameters is explored. The optimal structural parameter values of SCR are calculated through the coupling relationship function. The SCR volume of the optimal structural parameters is reduced by 23.82% and the pressure drop generated by SCR reactor is reduced by 10.38%, which not only lead to the reduction of fuel consumption and also save the space and energy on ship. Meanwhile, and the NOx conversion is decreased slightly to 0.51%.
