中小型化工企业在意大利分布广泛。特别是，他们操作分批和半分批工艺，根据工作订单工作，并大量使用已经安装了紧急救援系统（ERS）的多用途反应堆。批量方法是一种方法，其重点是找到反应器填充水平，该水平可以导致单相蒸汽流，无论是否发生外部火灾，以便安装的ERS可以保护反应器免受过压。在这项工作中，这样的方法已被修改，通过选择失控反应的设计附带的情况下，并结合了适当的优化程序的基础上拓扑标准。新的批量方法允许计算反应器填充水平，这是更合理的工业应用相对于由旧的方法预测的，而拓扑方法允许确定最小的定量给药时间能够保证反应器的安全性和高生产率。理论结果已经实验验证，使用反应量热实验获得的数据，在等周RC 1设备（1 L，Mettler Toledo）中进行，实施丙烯酸丁酯的溶液均聚的相关案例研究。
Small and medium chemical enterprises are widely diffused in Italy. Particularly, they operate batch and semi-batch processes working on job orders and making a massive use of multipurpose reactors having an Emergency Relief System (ERS) already installed. A batchsize approach is a method focused on finding the reactor fill level that can lead to a single phase vapor flow whether an external fire occurs, so that the installed ERS can protect the reactor from overpressures. In this work, such an approach has been revised, by choosing a runaway reaction as design incidental scenario, and integrated with a suitable optimization procedure based on topological criteria. The new batchsize approach allows for computing a reactor fill level which is much more reasonable for industrial applications with respect to that one predicted by the older method, while the topological approach permits to identify the minimum dosing time capable of guaranteeing both reactor safety and high productivity. Theoretical results have been experimentally validated using data obtained by reaction calorimetry experiments, carried out in an isoperibolic RC1 equipment (1 L, Mettler Toledo), implementing the relevant case study of the solution homopolymerization of butyl acrylate.
