摘要/Abstract

摘要： 针对目前化工安全评价方法中存在的主观性较强、不确定因素较多的问题,引入未确知测度理论,提出一种化工工艺本质安全度的评价方法。从物质、反应及工艺条件等方面选取评价指标,采用熵权理论确定各指标的权重;根据置信度识别准则判别安全度等级,并对工艺的安全度高低进行排序。应用该方法评估5条工艺路径的本质安全度,将结果与道化学法、本质安全优良性法(IBI)的评估结果对比。研究表明:用3种方法得到的评估结果基本吻合,证明了基于未确知测度理论的本质安全度评价法的可行性和有效性。

Abstract: To address the problem of subjectivity and uncertainty existing in the current chemical safety evaluation methods,the uncertainty measurement theory was introduced to establish an evaluation method of the inherent safety of the chemical process.Evaluation indexes involving material,the reaction and the process conditions were identified.The entropy theory and credible degree recognition were applied to determine the weights of the indexes and the process safety level respectively.And a comparison was made between the safety levels of different processes to choose the inherent safer one.This method was used to evaluate the inherent safety of five process routes.The results were basically consistent with those obtained by using the Dow's method and the Inherent Benign-ness Indicator (IBI).It indicates that the proposed evaluation method is feasible and effective.

Key words: uncertainty measurement theory, inherent safety level, entropy theory, credible degree recognition, chemical process evaluation
