摘要
在资源和能源日趋紧缺的背景下,开拓替代能源和新的化工产品技术路线势在必行。然而,目前对各种新技术方案的基础数据和系统分析比较薄弱,对产业布局和生态环境的长期影响有待深入研究。对近年来研究资源/能源化工复杂系统的建模、模拟、结构优化和系统集成问题的进展进行综述,运用过程系统投入产出分析的理论和方法,建立化工产品技术路线的全生命周期分析模型与集成的框架平台,研究资源、能源、技术、经济、环境等多因素综合优化评价问题。以煤气化合成气衍生的煤化工系统为基础案例,专门论述了在产品路线规划和过程合成中,集成优化、全生命周期评价和可持续性的研究进展。目标在于推进'技术—经济—环境—产业发展'多属性、多目标、多尺度系统集成的基础理论研究和技术创新。
In the background of global energy/resources shortage,alternative energy and new chemical processes are proposed,which are,however,not quantitatively and comprehensively evaluated,neither for long-term effect on the industrial sector and resources supply chain,nor for social development and ecological environment. We review advances in modeling,simulation,optimization,and integration of resource/energy chemical processes in recent years.The objective is to provide industry and decision makers with profound understanding of co-benefits and unintended impacts of the large-scale deployment of various process technologies on environment and resources in a life cycle perspective.By establishing life cycle models from feedstock,production,market,to recycling,integrated approaches are explored to evaluate the efficiency and sustainability of alternative processes.Furthermore,these approaches aim to rationalize and optimize flow-sheeting,reduce investment and operating costs,raise efficiency and minimize environmental impacts. Coal gasification syngas centered energy/chemical product chains are taken as the base cases.Multidimensional ＂ technical-economical-environmental-societal ＂ models are built,simulated,and optimized.Mass and exergy flow diagram,life cycle inventory,sustainability indicators are established.Resource/energy utilization efficiency,environmental impact,and economic benefits are quantitatively evaluated.Finally,aplatform to support the life cycle analysis and decision-making is constructed for process evaluation,integrated innovation and optimization of existing and potential alternative energy/chemical processes.
