Life Cycle Assessment (LCA) is a tool that aids in sustainable decision-making among product and process alternatives. When implementing LCA, the efficient and accurate modeling of chemical processes for Life Cycle Inventory (LCI) generation is still challenging. Challenges include a lack of systematic design and simulation tools and approaches to develop chemical process models for obtaining and analyzing more realistic LCI results. In this contribution, a novel process systems framework is proposed for estimating LCI results when implementing pollution control technologies. This framework involves the development and incorporation of pollution control unit (PCU) modules into process simulation and generation of LCI data associated with the PCUs for use in a sustainability evaluation. Different pollution control modules are designed for rapid LCI estimation and applied to obtain emissions, utility consumption, material, and land footprint results related to waste streams of a process simulation. Then, the LCI results are analyzed with the objectives of minimizing the environmental impact and utility consumption. The proposed framework is illustrated via a biomass/coal gasification process for syngas production with the end goal of acetic acid manufacturing. Results associated with this case study show that the developed framework can provide guidelines for sustainable decision-making based on generated LCI results.

用于快速生成生命周期清单以进行污染控制和可持续性评估的过程系统框架。

生命周期评估 (LCA) 是一种有助于在产品和工艺替代方案中做出可持续决策的工具。在实施 LCA 时,对生命周期清单 (LCI) 生成的化学过程进行高效、准确的建模仍然具有挑战性。挑战包括缺乏系统设计和模拟工具以及开发化学过程模型以获取和分析更真实的 LCI 结果的方法。在本文中,提出了一种新颖的过程系统框架,用于在实施污染控制技术时估计生命周期清单结果。该框架涉及污染控制单元 (PCU) 模块的开发和整合到过程模拟中,以及生成与 PCU 相关的 LCI 数据,以用于可持续性评估。不同的污染控制模块设计用于快速生命周期清单估算,并应用于获取与过程模拟的废物流相关的排放、公用设施消耗、材料和土地足迹结果。然后,分析 LCI 结果,以最大限度地减少环境影响和公用事业消耗。所提出的框架通过用于合成气生产的生物质/煤气化工艺来说明,最终目标是制造乙酸。与该案例研究相关的结果表明,所开发的框架可以为基于生成的生命周期清单结果的可持续决策提供指导。
