【摘要】 基于本质安全原理对化学工艺进行风险评价,以易燃性、易爆性、毒性、腐蚀性、反应热、化学活性、工艺温度、工艺压力和存储量9个指标,建立化学工艺的本质安全评价指标体系。采用基于遗传算法的Shepard插值算法对本质安全进行评价,以甲基丙烯酸甲酯的合成工艺路线为例进行分析,结果表明该方法适用于化学工艺本质安全评价,相对传统方法更加科学,能够有效对危险工艺进行选择,为政府监管部门和化工企业提供工艺选择决策技术。更多还原

【Abstract】 A framework based on inherent safety for risk assessment on chemical techniques was presented.Assessment criterions were involved with flammability,explosibility,toxicity,corrosivity,reaction heat,chemical activity,temperature,pressure and inventory.Genetic algorithm based shepard interpolation model was used for inherent safety evaluation.As a case study,an inherent safety evaluation of methyl methacrylate process routes was presented.The results showed that the model is more scientific than traditional method,which can give better results of techniques selection,and support the decision of government and enterprises.更多还原
