A methodology for the design of intensified processes that includes economic, sustainability, and inherent safety factors is presented. Given an original synthesis problem to produce a desired chemical from a set of feedstocks, a base design is first generated from which a gradual intensification procedure is carried out until a fully intensified design with a minimum number of pieces of equipment is achieved. A novel approach in this work is that in addition to economic and sustainability factors, inherent safety metrics are evaluated at each step of the intensification methodology. In particular, the evaluation of inherent safety poses an important challenge because of the hybrid types of equipment units that inevitably appear as part of the intensification task. An adjusted FEDI index is included for such an evaluation as part of the methodology. Two case studies, one dealing with the production of isoamyl acetate and another one with the production of dioxolane products, are taken to show the applicability of the intensification methodology. It is shown that a fully intensified structure does not necessarily represent the best option when the three metrics are taken into account.

一种过程强化方法,包括经济,可持续性和安全方面的考虑

提出了一种包括经济,可持续性和固有安全因素在内的强化过程设计方法。给定一个原始的合成问题,要从一组原料中生产所需的化学品,首先要进行基础设计,然后从中进行逐步强化程序,直到用最少的设备数实现完全强化的设计。这项工作中的一种新颖方法是,除了经济和可持续性因素外,在集约化方法的每个步骤都要评估固有的安全指标。特别是,固有安全性的评估提出了一个重要的挑战,因为设备单元的混合类型不可避免地出现在集约化任务中。作为该方法的一部分,还包括针对此类评估的调整后的FEDI指数。进行了两个案例研究,一个涉及乙酸异戊酯的生产,另一个涉及二氧戊环产物的生产,以表明强化方法的适用性。结果表明,当考虑到这三个指标时,完全强化的结构不一定代表最佳选择。
