Strategies for Inherent Safer Design during Chemical Process Development

Inherent safer chemical process design is a precedence technique to prevent human error and invalidation of facility and reduce the risk of chemical process. The opportunity for inherent safer chemical process design was analyzed by comparing the inherent safety design with the traditional design method. It is easier to design safer chemical process with low cost during the early stage of chemical process development. Strategies for inherent safer chemical process design were discussed during the phase of feasibility analysis, process research, concept design, foundation design and engineering design. The process for inherent safer chemical process design was presented. The inherent safety level can be improved by many measures, such as safer reaction route design, the simplification and optimization of process, the evaluation of inherent safety degree of different designs, etc.
