Green process systems engineering

对污染预防的追求，加上对环境可持续工艺和产品的压力和需求的增加，催生了流程行业的新规则和法规。根据联合国1987年布伦特兰报告，可持续发展的定义是“在不损害子孙后代满足自身需求的能力的情况下，满足当代人需求的经济发展”。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)开发一个综合的计算机辅助框架。该框架将通过纳入环境影响评估工具、生命周期分析、可持续性指标和固有安全概念来扩展传统的PSE方法。我们设想了一个框架，可用于：(1)对现有工艺进行工艺修改，以减少浪费和能源消耗，并提高效率；(2)在不利的环境条件或不断变化的法规下，采取适当的调度和反应操作措施，以将污染降至最低；(3)从现有技术的上层建筑中选择适当的控制选项；(4)开发符合经济、安全和环境考虑的新工艺；以及(5)建议稳健的绿色能源和电力生产路径。考虑经济学和绿色工程的概念对于保持盈利至关重要；否则将不会进行投资，环境保护将受到侵蚀。将审议一些案例研究，以说明这项研究的结果如何导致更环保和更有利可图的设计和/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.
