Chemical Processing - September 2007 - (Page 36) Rethin app ocess to pR fety sa ouaRh y Ro c The chemical indusTry relies on processes ThaT can pose hazards due to the nature of the materials and chemistry used (chlorine is toxic by inhalation, nitration reactions usually are highly exothermic) or the characteristics of the process variables (ammonia manufacture requires elevated pressure). so, effective process safety management is crucial. process risk reduction can involve limiting the likelihood of potential accidents or cutting their consequences. strategies fall into four categories: • Inherent. eliminate a hazard by using materials and process conditions that are non-hazardous. For example, replace a flammable solvent with water. • Passive. minimize the risk by process and equipment design features that decrease either the frequency or consequence of an incident without the active functioning of any device. For example, provide a containment dike around a flammable liquid storage tank. • Active. use controls, safety instrumented systems and g other emergency shutdown systems to detect hazardavoidin ore on an cus m ous process deviations and move the process to a safe Fo her th ards rat g them state. For example, install one foot below a tank haz ntrollin overflow a high level switch that, when tripped, will just co shot, stop a pump feeding the tank. der C. Hen Dennis chnology Inc. • Procedural. implement operating procedures, By rth Te Chilwo training, administrative checks, emergency response and other management approaches to prevent incidents or to minimize their effects. For example, mandate that an operator’s supervisor verify that the amount of a critical catalyst to a batch reaction is correct by independently weighing the catalyst before charging it to the reactor. k 36 • september 2007 www.chemicalprocessing.com http://www.chemicalprocessing.com
