“…The model was used to simulate the release of contaminants, interaction of aerosols with other particles in the atmosphere, the atmospheric dispersion of released aerosols, and the deposition of contaminants on the ground and surrounding infrastructure. A computer aided tool called the toxic release consequences analysis tool (TORCAT) was developed for consequences analysis and design improvement using ISD A c c e p t e d M a n u s c r i p t 24 principles (Shariff & Zaini, 2010). Exposure models are used to determine the extent and the degree of employee exposure to toxins and physical hazards and to determine effects of toxins on humans.…”

Among the process safety strategies, inherent safety, proposed by Kletz, has been widely accepted and applied for the preliminary design of chemical processes. Process optimization with safety aspect has usually focused on accident costs rather than risk. Additionally, the significance of inherent assessment for process optimization has been overlooked. Simultaneous optimization of risk with inherent safety and process economics can be more impactful in practical process designs. Therefore, a new methodology is consolidated in this paper, such that an external risk and process economics model is coupled with HYSYS to achieve an optimized process design. Here, process stream index (PSI) has been suggested to identify the critical process streams. For identified critical process streams, risk analysis and process economics are studied. Risk estimation and process economics parameters are studied in an external model by extracting information from HYSYS through VBA coding. For unacceptable risk, minimization guide word is used to improve the performance of critical streams. With inherent safety implementation, process economics is also found to be improved, as 3.2% less energy would be required without any significant change in ammonia product quantity. This approach would serve to deal safety with process attributes as multiobjective optimization method of process design.

“…They applied the proposed procedure for two case studies, a toxic release and a BLEVE/fireball, to determine the optimum number of storage tanks in a chemical plant. Another tool called "Toxic release consequence analysis tool" (TORCAT) was developed by Shariff and Zaini (2010) to analyze the consequence of a toxic release in order to evaluate the inherent safety level of different process options by determining the concentration of the released gas at a specific distance. Patel et al (2010) applied a "Computer Aided Molecular Design" (CAMD) technique to select inherently safer solvents for a solvent operation.…”

There are different well-established strategies for making a process plant inherently safer. The benefits of applying these strategies on reducing the overall risk inside a plant are obvious.However, some of these changes are rejected many times because they appear to be too costly.But if the effects of applying inherently safer design strategies are investigated not only on the processing costs of a plant but also on the potential accident costs, the decision would in fact be different. In this paper an optimization procedure is proposed which integrates both processing and accident costs for different design schemes. In this procedure, some of the design variables are chosen with regard to inherently safer design strategies. The objective function is the sum of accident costs and plant lifecycle processing costs. For assessing accident costs, consequence modeling techniques and probit functions are applied. Consequence modeling formulas and an objective function are codified in an optimizer package (MATLAB) and to accomplish the optimization process a process simulator (called HYSYS) is coupled with this package. The application of the proposed procedure is demonstrated by selecting an optimum process scheme for a Refrigeration plant as a case study.
