Inherent Safety and Process Design a Literature Study. Plant Design Series

摘要

The aim of process design is to create a process that is profitable, economic,safe, environmentally benign and user friendly. This is achieved by the optimization of process alternatives according to economic and functional criteria. It is required that the safety of a process plant fulfills a certain level and because of general requirements, company image and also economic reasons: in fact an unsafe plant cannot be profitable, due to losses of production and capital. The safety of a chemical process can be achieved through internal (inherent) and external means. The inherent safety is related to the intrinsic properties of the inherent safety to remove hazards rather than to control them by added-on protective systems, that is the principle of external safety. The largest payoffs are achieved by verifying that inherent safety has been considered early and often in the process and engineering design.
