This paper presents the Life Cycle Assessment (LCA) of a glycerine production process as one of the most energy-intensive chemical processes. The utilisation of biomass as a solution to replace the current fossil fuels in the process is proposed. To do so, different energy mix scenarios are defined to moderate the impacts of glycerine production and utility generation during the energy transition period. In this research, the implementation of LCA in conjunction with Cumulative Exergy Demand to evaluate the sustainability of the developed energy mix is proposed. This LCA study confirms without retrofitting the core of the glycerine process technology, it is possible to reduce the environmental impacts through the step-wise introduction of biomass into the energy mix, resulting in four different scenarios. This study also confirms that, according to the discernibility analysis through Monte Carlo simulations, LCA results are responsive and sensitive to the portion of biomass in each energy mix scenario. Moreover, this study shows that the overall anthropogenic environmental impacts of the glycerine production process are reduced (41% according to Cumulative Exergy Demand) through natural gas to biomass energy transition. However, the biomass-based scenarios are less sustainable than the natural gas scenarios regarding photochemical oxidant formation.

本文介绍了甘油生产过程的生命周期评估（LCA），这是最耗能的化学过程之一。提出了利用生物质作为解决方案中替代当前化石燃料的解决方案。为此，定义了不同的能源组合方案，以缓和能源过渡期间甘油生产和公用事业发电的影响。在这项研究中，提出了将LCA与累计火用需求结合起来以评估已开发能源组合的可持续性的实施方案。这项LCA研究证实，无需改造甘油工艺技术的核心，就可以通过将生物质逐步引入到能源结构中来减少对环境的影响，从而产生四种不同的情况。这项研究还证实，根据通过蒙特卡洛模拟进行的可分辨性分析，LCA结果对每种能源组合方案中的生物质部分均具有响应性和敏感性。此外，这项研究表明，通过天然气向生物质能的转化，甘油生产过程对人为的总体环境影响降低了（根据累积火能需求量的41％）。但是，就光化学氧化剂的形成而言，基于生物质的方案比天然气方案的可持续性差。这项研究表明，通过天然气向生物质能的转化，甘油生产过程对人为的总体环境影响降低了（根据累积火能需求量的41％）。但是，就光化学氧化剂的形成而言，基于生物质的方案比天然气方案的可持续性差。这项研究表明，通过天然气向生物质能的转化，甘油生产过程对人为的总体环境影响降低了（根据累积火能需求量的41％）。但是，就光化学氧化剂的形成而言，基于生物质的方案比天然气方案的可持续性差。
