摘要

新兴生物基技术的环境绩效必须在其发展的早期阶段进行评估,当时该过程仍然可以进行修改,以实现可持续的优化,即包括环境、社会和经济方面。生命周期分析(LCA)方法已被公认为环境分析的有效解决方案。然而,在新合成路线生态设计的初始阶段,在实验室规模上获得的数据是不完整的,这使得生命周期的清单变得复杂。将流程建模/仿真工具与LCA相结合已被证明是提供库存数据的有效解决方案。过程的模拟是基于模型的选择,允许在生产规模上开发技术的环境,能源和经济优化。反应和分离步骤模型的选择必然会对环境评价的结果产生重大影响。本文致力于研究反应途径建模复杂程度对尿素甲醇解制碳酸二甲酯(DMC)过程环境评价的影响。

Ecodesign of a process for dimethyl carbonate: Influence of the degree of modelling of the methanolysis of urea
The environmental performance of emerging bio-based technologies must be assessed at an early stage of their development, when the process can still be modified for sustainable optimization, i.e. including environmental, social and economic aspects. The Life Cycle Analysis (LCA) methodology is already recognized as an effective solution for environmental analysis. However, the data obtained at the laboratory scale are incomplete in the initial stage of the eco-design of a new synthesis route, which complicates the inventory of the life cycle. Coupling a process modelling/simulation tool with LCA has proven to be an effective solution for providing inventory data. The simulation of a process is based on the selection of models allowing the environmental, energy and economic optimization of a technology to be developed on the production scale. The choice of models for the reaction and separation steps will certainly have a significant impact on the results of the environmental assessment. This article is dedicated to the study of the impact of the degree of complexity of the modelling of the reaction pathway on the environmental assessment of the process of methanolysis of urea to produce dimethyl carbonate (DMC).

期刊介绍: MATEC Web of Conferences is an Open Access publication series dedicated to archiving conference proceedings dealing with all fundamental and applied research aspects related to Materials science, Engineering and Chemistry. All engineering disciplines are covered by the aims and scope of the journal: civil, naval, mechanical, chemical, and electrical engineering as well as nanotechnology and metrology. The journal concerns also all materials in regard to their physical-chemical characterization, implementation, resistance in their environment… Other subdisciples of chemistry, such as analytical chemistry, petrochemistry, organic chemistry…, and even pharmacology, are also welcome. MATEC Web of Conferences offers a wide range of services from the organization of the submission of conference proceedings to the worldwide dissemination of the conference papers. It provides an efficient archiving solution, ensuring maximum exposure and wide indexing of scientific conference proceedings. Proceedings are published under the scientific responsibility of the conference editors.
