摘　　要：针对目前应用最为广泛的8种焦化脱硫工艺,采用多级模糊数学模型,对焦炉煤气脱硫工艺进行了综合评价。模糊评价的因素集由环境指标、经济指标和技术指标三大类因素构成,其中每一因素集又包括更具体的评价指标;通过确定各具体性能指标的隶属函数,并应用层次分析法(AHP)确定各因素集的权重矩阵,对每一大类因素进行初级综合评价,进一步在初级评价结果基础上进行二级模糊综合评价。结果表明,根据最大隶属度原则,PDS+栲胶法是综合性能最优的焦化脱硫工艺。The multi-level fuzzy mathematics model was applied to evaluate the comprehensive performance of the current most widely used eight kinds of coke oven gas（COG） desulfurization processes.The first-level factors include environmental indicators,economic indicators and technologies parameters,of which each consists of a few second-level factors.Firstly,the influence of every second-level factor on assessment was expressed in membership functions.Secondly,the analytic hierarchy process（AHP） was used to achieve the weight matrix of each factor set.The primary comprehensive assessment was conducted for the first-level factors,then the secondary comprehensive assessment was conducted on the basis of results from primary assessment.According to the rule of maximum membership value,it shows that the PDS ＋ Vegetable Tannin Extract Method is the optimal technology for coke oven gas COG desulfurization.
