The industrial application of the DIERS Bench-Scale Apparatus to classify thermal runaway reactions as tempered, gassy, or hybrid type of reactive systems was first reviewed in 1987 by Leung and Fauske. Since then a low-cost Reactive System Screening Tool (RSST) has augmented the vent sizing package in collecting thermal runaway data useful for vent sizing applications using simple equations. The formal vent sizing methodology has also been enhanced in the area of an analytical model for hybrid system analyses. The data base of tested reacting systems has been greatly enlarged with both vent sizing and thermal data acquisition in mind. This paper presents recent vent sizing and thermal data testing results for approximately fifty chemical systems of industrial application. These data illustrate the widely varying nature of thermal runaway reactions and their consequence on pressure relief vent sizes. 7 refs., 4 figs., 2 tabs.
