本文提出了一种新的系统程序，以帮助工艺设计师综合的分离过程，是经济高效和环境可持续发展。所提出的方法是一种混合的方法，包括算法和启发式处理的符号和数值数据。启发式方法，应用基于经验的规则和热力学的见解选择的分离操作，用于降低合成搜索空间的复杂性和大小。然后使用数学建模的算法方法来制定和解决剩余的问题。所有的环境影响都通过过程和产品生命周期的所有输入和输出进行评估。所有的标准同时考虑，和多标准优化问题，这是制定使用现有的计算机辅助分子设计和选择工具，和计算机辅助工艺设计和分析技术，解决构建一个权衡集。然后进一步分析所构造的折衷集以选择有希望的解决方案。拟议的方法是使用现有的软件工具。开发的方法的应用说明在一个案例研究。研究了废水中苯酚的回收工艺。该工艺用于酚醛树脂制造。开发的方法可以选择解决方案，是在所需的经济性能最小的环境影响。
This paper presents a new systematic procedure to help process designers synthesizing a separation process that is economically efficient and environmentally sustainable. The proposed methodology is a hybrid method consisting of algorithmic and heuristic processing of symbolic and numeric data. The heuristic approach, applying experience-based rules and thermodynamic insights for selection of separation operations, is used to reduce the complexity and size of synthesis search space. The algorithmic approach using mathematical modeling is then used to formulate and solve the remaining problem. All environmental impacts are evaluated through all input and output of process and product life cycles. All criteria are simultaneously considered, and the multi-criteria optimization problem, which is formulated using existing computer-aided molecular design and selection tools, and computer-aided process design and analysis techniques, is solved to construct a trade-off set. The constructed trade-off set is then further analyzed to select a promising solution. The proposed methodology is implemented using available software tools. Application of developed methodology is illustrated in a case study. We investigate process for phenol recovery from wastewater. This process is used in phenolic-resin manufacturing. The developed methodology can select solutions that are minimal environmental impacts at a desired economic performance.
