Presented by:

Georges A. Melhem, Ph.D., FAIChE, Vice Chair of DIERS and President and Chief Executive Officer of ioMosaic

How confident are you when it comes to evaluating emergency relief systems design for runaway reactions?  Are you aware of the factors that impact reaction rates and the role of thermal stability?  What methodology is most effective for analyzing process chemistry and thermochemistry? 

Understanding process chemistry is key to reducing the risk of runaway reaction incidents. Failure to adequately understand and assess process chemistry and thermochemistry can result in erroneous scale-up as well as erroneous sizing/evaluation for relief systems. Join us on January 20, 2021 as Dr. Melhem presents the second installment of DIERS Technology Fundamentals on how methodology developed by the AIChE Design Institute for Emergency Relief Systems (DIERS) for the design and operations of pressure relief and effluent handling systems improves process safety.

Prevention of accidental releases begins with a thorough understanding of process chemistry and emergency relief system design strategies.  The AIChE Design Institute for Emergency Relief Systems (DIERS) was formed on this mandate in 1976 and has developed relief and effluent handling systems design and evaluation methods now used worldwide.  This webinar is the second installment of DIERS Technology Fundamentals. The session will cover runaway reactions characterization methods and provide a useful summary of thermal stability indicators. A quick overview of two-phase flow methods is presented. Methods for sizing relief systems for runaway reactions are also discussed.

Georges A. Melhem, Ph.D., FAIChE is President and Chief Executive Officer of ioMosaic, and is an internationally known expert in the areas of pressure relief and flare systems design, chemical reaction systems, process safety, and risk analysis.  As the founder of ioMosaic Corporation, he has over 30 years of engineering and process safety experience, and has participated in numerous risk management, consequence analysis, and quantitative risk assessment studies for commercial and government clients.  He currently serves the Vice Chair/Secretary for DIERS and he has been active in the organization for over 20 years.

Dr. Melhem has provided litigation support and expert witness testimony to domestic and international cases including disputes over recognized and generally accepted good engineering practices (RAGAGEP), design practices for flare systems and effluent handling, and numerous major fire and explosion events.  Dr. Melhem is also the author/co-author of multiple books, many technical papers and presentations, and hundreds of technical reports regarding various aspects of risk assessment.
