  • Designing sustainable proceses using environmental and economic assessment
    Krajnc, Damjan, 1976- ; Glavič, Peter
    The paper presents a systematic approach to the problem of sustainable process synthesis of large-scale chemical processes with respect to the resource usage and other environmental considerations. ... The process design is composed of three main steps, i. e. simulation step, conceptual design step (extended Pinch design method, determination of promising modifications, their assessment regarding sustainability, selection of the most promising modification) and rigorous design step (structural and parameter optimization). The ecological considerations are combined with the economic assessment of process design using indicators of process sustainability. Environmental impact of process design is quantified by a set of sustainable process indicators (specific energy and water consumption, global warming potential, acidification potential, etc.). With suitable weightings, a composite index of process sustainability is defined and served as an objective function for the assessment of process modifications. A simplified ammonia production is presented to demonstrate the potential of the approach assisting in arriving at environmentally friendly and economically favorable process design.
