CEP: December 2014 Thirty years ago this month, the worst chemical accident in history occurred. The catastrophic release of of methyl isocyanate from a pesticide plant in Bhopal, India, resulted in thousands of deaths and hundreds of thousands of injuries. Two articles and the Process Safety Beacon in this issue review some of the lessons learned from that tragic incident. Other topics this month include fine-particle filtration, avoiding fluidization pitfalls and robust process control. EditorialIt’s All About the CultureDecember 3 marks the 30th anniversary of the worst chemical accident in history — the catastrophic release of methyl isocyanate (MIC) from a pesticide plant in Bhopal, India, in 1984 that resulted in thousands of deaths and hundreds of thousands of injuries. Two articles and the Process Safety Beacon in this issue review some of the lessons learned from that tragic incident.While putting this issue together, I came across the results of a survey conducted recently by Dräger, a manufacturer of industrial gas-detection equipment, that asked frontline workers and safety managers in the oil and gas sector about their perspectives on the state of safety in their industry. In general, the respondents believe the industry as a whole is committed to safety, although they say that opportunities for improvement exist.Read more Share Consider the Role of Safety Layers in the Bhopal Disaster December2014SafetyDr. Ronald J. WilleyAs the situation unfolded, numerous layers of protection failed. Take a look at the safety layers that worked and those that did not, and ask whether there are similarities at your facility. Apply Can’t Rather than Don’t to Your Process December2014SafetyWilliam LevinsonMany safety systems rely on human intervention to prevent incidents. A different approach is to make it impossible for a catastrophic accident to occur. Learn how to implement the Can’t Rather than Don’t principle. Choosing a Fine-Particle Filtration System December2014Reactions and SeparationsBarry A. PerlmutterFiltration technology has advanced to meet the demand to remove small particles at low concentrations. When designed correctly, a candle filter or a pressure plate filter may be a more-efficient replacement for a traditional filtration scheme. Avoid Fluidization Pitfalls December2014Back To BasicsRaymond Cocco, S. B. Reddy Karri, Ted KnowltonFluidized beds are susceptible to such problems as bed slugging, loss of fines, and gas bypassing. This article explains how to avoid these pitfalls. Account for Uncertainty with Robust Control Design - Part 2 December2014InstrumentationSachi Dash, Rakesh Joshi, J.
