“…As risk can be associated with human health, the environment, material and equipment, utilities, and so forth, it is difficult to quantify risk in terms of a single metric despite substantial progress in this area . Whenever significant risk is detected in a chemical process, process engineers schedule maintenance, and/or design changes .…”

A method of designing model-predictive safety systems that can detect operation hazards proactively is presented. Such a proactive safety system has two major components: a set of operability constraints and a robust state estimator. The safety system triggers alarm(s) in real time when the process is unable to satisfy an operability constraint over a receding time-horizon into the future. In other words, the system uses a process model to project the process operability status and to generate alarm signals indicating the presence of a present or future operation hazard. Unlike typical existing safety systems, it systematically accounts for nonlinearities and interactions among process variables to generate alarm signals; it provides alarm signals tied to unmeasurable, but detectable, state variables; and it generates alarm signals before an actual operation hazard occurs. The application and performance of the method are shown using a polymerization reactor example.

“…Process routes are chosen based on economic performance which compromises other criteria like environmental impact, health, operational and safety issues 6. Selection of the process route might be based on at least one out of three groups of selection methods: the process simulations of proposed process flow sheet 6–9, optimization techniques 6, 7, 10, 11 or index methods oriented on assessment of process safety 12–14 and sustainability of the process 15. However, in industry, practice during that phase of design identification and assessment of process hazard is done too rarely 16.…”

Process design management system is the essential computer-aided design type of software used in design and 3D modeling of process plants. Actually, it is a management center of process plant projects which allows designers and engineers from various disciplines to concurrently create, control, and manage changes to the plant design and other related engineering data. Some methods for achieving the inherently safer designs guide the location of process equipment and utilities. Therefore, there is room for close interactions between 3D modeling and methods to assess the inherent safety. The feasibility of integration of the Fire and Explosion Index into 3D modeling of industrial chemical processes is evaluated and supported by a case study. The importance of the presented concept as key part of such management philosophies like the lean design and the building information modeling is highlighted.
