The Application of Multi-Compartment Models for Regional Environmental Comparison of Process Design Alternatives

Anumber of methodologies have been presented in the literature to meet the demand for environmental comparison of process design alternatives. However, the application of these methodologies in practice has been limited by subjectivity, uncertainty and resource requirements. In this paper, a multi-compartment model, using readily available data and associated assumptions, is presented as a potential tool for environmental comparison of process design alternatives. The suitability of the model to provide a discriminatory basis for comparison is discussed in terms of trends, quantitative uncertainty and limitations.
