DEVELOPMENT OF INFORMATION INFRASTRUCTURE FOR ENVIRONMENTALLY CONSCIOUS CHEMICAL PROCESS DESIGN

1.开发化学过程环境影响的评价方法(1)化学过程的综合环境评价，(2)过程环境变化的评价，(3)设计阶段的不确定性评价，研究并提出了一种在工业清洗过程中根据化学物质的使用来选择环境评价项目的程序。2.开发了一种在化工工艺设计中使用环境评价结果的方法。以聚酯回收工艺为例，构建了一个详细的活动模型，描述了从材料设计到工艺设计的整个过程生命周期。分析了各活动的产出项目和产出机制。概念性地设计了一个提出备选方案并将其表示为过程模型的支持系统。3.开发了一种在包括经济和环境在内的多个目标下进行决策的方法。4.实现了支持工艺设计的信息基础设施，获取全生命周期信息，完成了支持方案生成、工艺综合、工艺设计、工艺评价和决策的总体系统的概念设计，并对本研究设计的信息基础设施进行了实际实施。

1.Development of an evaluation methodology of environmental impact of chemical processMethodologies for (1)Integrated environmental evaluation of a chemical process, (2)Evaluation of the changes in the environment of a process, (3)Evaluation of uncertainty in the design phase, were developed to support the environmental evaluation in the early phase of chemical process design.A procedure to select items for environmental evaluation depending on the use of chemical substances in the industrial cleaning process was investigated and proposed.2.Development of a methodology to employ results of environmental evaluation in the chemical process designA detailed activity model representing a process lifecycle from material design to process design was constructed using an example of PET recycling process. Output items and mechanisms of each activity were analyzed. A support system to propose alternatives and to represent them as process models was conceptually designed.3.Development of a methodology to make decisions under multiple objectives including economics and environmentTwo methodologies to combine multiple objectives in the decision-making were developed. One is to integrate multiple objectives into one indicator by weighting, and another is to consider them independently using eco-efficiency analysis.4.Implementation of an information infrastructure for the support of process design acquiring lifecycle informationThe conceptual design of the total system which supports alternative generation, process synthesis, process design, process evaluation and decision-making was completed.As a future study, actual implementation of the information infrastructure designed in this study should be carried out.
