Green process systems engineering

对防止污染的追求，加上对环境可持续的工艺和产品的压力和需求增加，在加工工业中产生了新的规则和条例。根据1987年联合国布伦特兰报告，可持续性被定义为“满足当代人需求而不损害后代人满足其需求能力的经济发展”。这项研究将解决以可持续和安全的方式设计和管理化学和生化过程的挑战。这项研究的长期目标是为绿色（可持续）过程系统工程（PSE）开发一个集成的计算机辅助框架。该框架将通过结合环境影响评估工具、生命周期分析、可持续性指标和固有的安全概念，扩展传统的PSE方法。我们设想了一个框架，可以用来：(1)对现有工艺进行工艺修改，以减少浪费和能源消耗，提高效率；(2)在不利环境条件或法规变化的情况下，采取适当的调度和反应性操作措施，以尽量减少污染；(3)从现有技术的上层结构中选择适当的控制方案；(4)开发符合经济、安全和环境考虑的新工艺；(5)提出稳健的绿色能源和电力生产路径。为了保持盈利能力，考虑经济和绿色工程的概念是必不可少的；否则投资不会产生，环境保护也会受到侵蚀。将考虑一些案例研究，以说明这项研究的结果如何能够导致更环保和有利可图的设计和/或生产操作。

The quest for pollution prevention, coupled with increased pressure and demand for environmentally sustainable processes and products, have spawned new rules and regulations in the process industry. Sustainability is defined as "economic development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs", according to the 1987 Brundtland Report of the United Nations. This research will address the challenge of designing and managing chemical and biochemical processes in a sustainable and safe way. The long term objective of this research is to develop an integrated computer-aided framework for green (sustainable) Process Systems Engineering (PSE). This framework will extend upon the traditional PSE approach through the incorporation of environmental impact assessment tools, life-cycle analysis, sustainability metrics, and inherent safety concepts. We envision a framework that can be utilized to: (1) Perform process modifications on existing processes to reduce waste and energy consumption, and improve efficiency, (2) Take appropriate scheduling and reactive operating actions to minimize pollution under adverse environmental conditions or under changing regulations, (3) Select appropriate control options from a superstructure of available technologies, (4) Develop new processes that abide to economic, safety, and environmental considerations, and (5) Suggest robust green energy and power production pathways. The consideration of economics along with concepts of green engineering is essential in order to preserve profitability; otherwise investment will not occur and environmental protection will be eroded. A number of case studies will be considered in order to illustrate how the findings of this research can lead to greener and profitable designs and/or production operations.
