Vent sizing Fauske method

If Fauske s method yields a signifieantly different vent size, then the ealeulation should be reviewed. 

Experimental data can be obtained from the DSC and from reaction calorimeters for the conditions of the desired reactions, and from the DSC, the ARC, the Reactive System Screening Test (RSST—Fauske and Associates) and from the Vent Size Package (VSP) for conditions allowing undesired reactions. The pressure effect can be studied using the ARC or DIERS methods. From the results of these tests, the rate of temperature rise and the maximum acceptable conditions for specific equipment can be calculated. The same holds for the pressure rise rate. 

Vapour-pressure systems, where the pressure in the reactor is entirely due to the vapour pressure of the reaction mixture, are common in the chemical industry. A large number of vent sizing methods, both pre- and post-DIERS, are applicable to vapour pressure systems. The methods of Leung - and Fauske M both derived from DIERS work, are now widely used.
