  3. Abstract:
  4. A comprehensive representation of the environmental impact of a plant should incorporate not only the process variables that mainly affect the generation step but also the non-process ambient conditions that have influence on the dispersion step. Albeit, at best, only the process-related variables can be manipulated in order to optimize the environmental behavior of the process. In this study, an environmental model is coupled with a chemical process model. The approach is applied to an existing nitric acid production plant to study the effects of selected process variables on the environmental impact of the process. The insights that this approach provides can be used in retrofit studies to define the ultimate potential of the process in terms of source reduction as well as the appropriate direction of any modifications. The computer-aided integration of the two models improves the accuracy of the sensitivity analysis. It also makes the results much more realistic which is the key point in implementation of the proposed modifications. The environmental fate of the pollutants, i.e., nitric oxides, is programmed as a dispersion model. The model is linked to a process simulator that contains the process model. Sensitivity analysis of the environmental impact of the process has successfully revealed the most significant parameters that can affect the overall environmental performance of the plant
