VSP2™ – Vent Sizing Package 2

Fauske & Associates' Vent Sizing Package 2™ (VSP2™) utilizes state-of-the-art DIERS technology to obtain critical "off-normal" process design data. VSP2™ tests are used to model such upset scenarios as loss of cooling, loss of stirring, mischarge of reagents, mass-loaded upset, batch contamination and fire exposure heating. Tests can be run in a "closed" or "open" test cell mode, allowing for direct venting simulation. Test data include adiabatic rates of temperature and pressure change which can be directly applied to process scale to determine relief vent sizes, quench tank designs and other relief system design parameters related to process safety management.

The VSP2^TM is a true adiabatic safety calorimeter for process hazard characterization.

Its versatile design directly simulates process conditions.

• Loss of cooling or agitation
• Accumulation or mischarge or reactants
• Contamination of batch
• Thermally initiated decomposition
• Resident incubation time
• In-situ liquid/gas dosing or sampling
  

Obtain complete chemical system data.

• Low thermal inertia testing allows data to be directly applied to process scale
• Temperature and pressure rise rates applicable to relief system design
  "Based on DIERS two-phase flow technology, recognized by OSHA as an example of
  “good engineering practice”
