Fauske Adiabatic Calorimeters

Adiabatic Calorimetry from Fauske and Associates.

In the late seventies the American Institute of Chemical Engineers (AIChE) initiated a research project investigating various aspects of reactor vent sizing. This research project was to be known as DIERS (Design Institute for Emergency Relief Systems) and a newly formed company called Fauske and Associates (FAI) were awarded the contract as lead investigators. This was due to Hans Fauske and his colleagues’ standing as world experts on two-phase flow which was thought to be a significant aspect when considering relief systems. The DIERS project formally finished in the mid-eighties but the worldwide DIERS community is still active and FAI are still active in the discussions and developments in vent sizing methodology.

One of the main findings of the DIERS project was that a suitable piece of laboratory equipment was required to investigate the specific chemical system at the upset conditions. This measured data was then able to be used in the DIERS methodology to determine the various aspects of the relief system. During DIERS FAI designed the DIERS Benchscale Apparatus. This was then later commercialised by FAI as the VSP and in a simpler form the RSST. Today FAI manufacture the Vent Sizing Package (VSP2) apparatus and the Advanced Reactive System Screening Tool (ARSST) and these can be found in many Hazard Evaluation labs around the world.
