Designing Emergency Relief Systems for Runaway Reactions

Do you suffer from the ERS design ostrich syndrome? Most companies are well-equipped to perform emergency relief system (ERS) design for single-phase flow and non-reactive systems. Existing standards and recommended engineering practices developed by organizations such as the ASME, NFPA, API, and AIChE's CCPS enable a competent engineer with proper training to perform such calculations with a high degree of confidence and accuracy. Relative systems, however, are more complex, and may be susceptible to fire-induced and process-induced runaway reactions. This paper provides guidance that applies to reactive systems subject to process- and fire-induced runaway reactions, tanks that store reactive materials, and two-phase flow of reactive materials.
