Vent Sizing, Relief System Design, Reactive Chemistry and Role of Two-Phase Flow

Posted by The Fauske Team on 09.11.19

Unlike other emergency vent sizing courses, this curriculum highlights simplified calculation methods capable of giving safe - but not overly conservative - relief system designs, with an emphasis on reactive chemistries and the role of two-phase flow. The course will be provided October 16-18 at the Burr Ridge (Chicago) Headquarters of Fauske & Associates, LLC (FAI). 

runaway chemical ventBenchmarking of these methods will be illustrated with incidents and available plant data. Utilization of methods and equations will be demonstrated through practical design examples, covering vapor, gassy and hybrid systems.

Attendees will participate in group workshops and complete an independent quiz at the end of the course in order to ensure comprehension of the material. A laboratory session demonstrating experimental techniques will be held the afternoon of October 18, but is optional.

FAI is accredited through International Association for Continuing Education and Training (IACET)and FAI University course attendees are awarded CEUs upon meeting all the necessary requirements. FAI University offers a wide array of training courses globally to augment our customized testing, engineering and consulting services.
