Fuzzy Synthetic Evaluation of Flue Gas Simultaneous Desulfurization and Denitrification Technology

Abstract:

As choosing a combined SO₂/NOx removal technology, there are many factors, which all have fuzzy character. Therefore the comprehensive fuzzy evaluation is the best method. In this paper a two-stage fuzzy mathematics model is presented to evaluate the comprehensive performance of combined SO₂/NO_X removal technology by determining factor set, evaluation set, evaluation matrix and weighting set. This evaluation model takes all factors into account while emphasizing key points by choosing the two arithmetic operators max-product and add-product. Eight kinds of important combined SO₂/NO_X removal technology, including activated carbon, CuO, NO_XSO, SNAP, WSA-SNO_X, SNRB, Parsons flue gas process and electron-beam method, are evaluated and the evaluated result is presented. In the situation as the paper assumed, WSA-SNO_X technology is the best.
