This emergency vent sizing course will provide a practical approach to designing and evaluating relief systems. This course will emphasize reactive chemistry upset scenarios, ensuring that your relief system is adequately sized for these often worst-case scenarios. The Fauske team will highlight experimental design and data analysis to ensure the required data are appropriately collected and the necessary source terms are extracted.


Simplified and minimum best practice methodologies, including the Fauske General Screening Equation and Fauske Vapor/Gas Methodology will be covered in detail highlighting the role of two-phase flow. Real example calculations for reactive and non-reactive vapor (tempered), gassy (non-tempered), and hybrid systems will be covered including discussion on selecting the necessary inputs and assessing the results.


In situations where the assumptions are not sound or limitations apply restricting the applicability of the simplified methodologies, the Fauske team will provide examples utilizing our preferred advanced methodology (i.e. the Leung Omega Method).

This twelve-hour course will be broken up into three four-hour sessions, and is ideal for those with little to no experience with adiabatic calorimetry or designing emergency relief systems and those interested in or with access to the Fauske tools: the Advanced Reactive System Screening Tool (ARSSTTM), Vent Sizing Package 2 (VSP2TM), and/or Fauske’s Emergency Relief System Tool (FERST) powered by CHEMCAD. Interested attendees will receive a free trial of FERST.
