Method of Desulfurization Process Selection Based on Improved Fuzzy Comprehensive Evaluation: A Case Study of Papermaking Desulfurization in China

Abstract

With the increasingly prominent global energy and environmental problems, more and more enterprises have been required to desulfurize the exhausted gases. Different enterprises have different demands for the desulfurization process, thus the choice of desulfurization process methods has become a focus of attention. Since the evaluation of the desulfurization process involves many factors, this paper proposes an improved fuzzy comprehensive evaluation method to evaluate the selection of desulfurization process when the traditional evaluation method is not applicable. Firstly, an evaluation system with two rating indicators was constructed, which considers the subjective and objective weights comprehensively. Secondly using the two hierarchical indicators, an effective desulfurization process method was obtained according to the principle of maximum membership degree. Finally, we took a real papermaking factory as an example to illustrate the detailed implementation processes of this method. The result shows that the model could be used as a comprehensive evaluation tool to select desulfurization scheme or optimize the desulfurization process.

Synthesis of t‐B.PWFe/NiO nanocomposite as an efficient and heterogeneous green nanocatalyst for catalytic oxidative‐extractive desulfurization of gasoline

“…From the perspective of environmental benefits and increase in product quality, more enterprises need to desulfurize the petroleum products, especially gasoline, so the choice of the desulfurization process method has become the focus of attention of various industries 2,3 . At present, most of the countries evaluation of this process is based on the experience of industry experts, and the selection of the desulfurization process is determined by economic, technical, or the desulfurization effect unilaterally, which lead to the results of evaluation and selection that are not always scientific and well reasonable 4,5 . Thereupon, without effective help from chemistry, the capabilities of oil would never have been realized.…”

Hydro-desulfurization (HDS) is one of the most important petrochemical processes for the removal of sulfur-containing hydrocarbon fuel oils.…”

Reversible Removal of SO2 with Amine-Functionalized ZIF8 Dispersed in n-Heptanol

“…With the rapid development of the industry, air pollution has become an accompanied increasingly serious problem. , In recent years, the “haze problem” that erupted in most areas of China once again made people aware of the harmfulness of air pollution and the importance of environmental protection. SO 2 released from direct combustion of coals could interact with other components in the atmosphere (such as nitrogen oxides, water vapor, etc.)…”

Resource efficiency improvement: zero waste discharge planning in a pulp-and-paper firm under uncertainties

“…Inherent techno-economic uncertainties of zero-waste discharge programs need to be accounted for evaluating wastewater discharge and energy conservation are still underdeveloped and there are different approaches in the studies (Tseng et al , 2020). For instance, Wang et al (2019) applied fuzzy comprehensive evaluation method to assess the total impact of uncertain information on the overall performance score. Sustainable assessment has been approached with other methods.…”
