Adiabatic Calorimeters

In the late 1970s, 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-1980s but the worldwide DIERS community is still active and FAI are still active in the discussions and developments in vent sizing methodology.

Advanced Reactive System Screening Tool (ARSST)

In the mid-1980s, FAI introduced the RSST. In 1998, this was superseded by the Advanced Reactive System Screening Tool (ARSST). The ARSST was designed for hazards assessors who require basic…

Vent Sizing Package 2 (VSP2)

The Fauske VSP is a laboratory tool which allows a hazards assessor to collect precise ‘off-normal’ process design data. Using the VSP calorimeter, experiments can be performed to model upset…
