Adiabatic Calorimetry Contract Testing

The ARC provides thermal hazard evaluation of products, reaction mixtures and intermediates. The experimental results are used for reactor and pilot plant safety analysis. It determines the relationship between time, temperature, and pressure for exothermic reactions. Thermal and pressure hazard parameters related to ARC data include:

  • Heat generation rates
  • Onset temperature
  • Decomposition temperature of the mixture
  • Adiabatic temperature rise
  • Pressure generation rate
  • Time to maximum rate
  • Temperature of no return
  • Self-accelerating decomposition temperature

Our ARC contract testing service test protocol conforms to ASTM standard E 1981, “Standard Guide for Assessing the Thermal Stability of Materials by Methods of Accelerating Rate Calorimetry.” In addition, we have a variety of ARC test cells that can accommodate all of your ARC testing needs.

ARSST (Advanced Reactive System Screening Tool)

Low Phi- factor adiabatic calorimeter testing provides data for relief system design, safe scale-up of chemical processes and changes to process recipes. FAI has been the industry leader in adiabatic calorimetry since the concept of DIERS testing was first introduced in 1985. Safe process design requires knowledge of chemical reaction rates, character and energy release – all of which can be obtained from a low phi factor adiabatic calorimeter such as the VSP2 or ARSST.

The ARSST (Advanced Reactive System Screening Tool) can provide thermal data required for safe scale-up of chemical processes and changes to process recipes. A variety of process upset conditions can be tested to satisfy hazards identified by a PHA or HAZOP study. The low phi factor allows the heat and gas generation rates to be measured which leads to the appropriate design of emergency pressure relief systems.

VSP (Vent Sizing Package)

Low Phi-factor adiabatic calorimeter testing provides data for relief system design, safe scale-up of chemical processes and changes to process recipes. FAI has been the industry leader in adiabatic calorimetry since the concept of DIERS testing was first introduced in 1985. Safe process design requires knowledge of chemical reaction rates, character and energy release – all of which can be obtained from a low phi factor adiabatic calorimeter such as the VSP2 or ARSST.

The VSP2 (Vent Sizing Package 2) can provide thermal data required for safe scale-up of chemical processes and changes to process recipes. A variety of process upset conditions can be tested to satisfy hazards identified by a PHA or HAZOP study. The low phi factor allows the heat and gas generation rates to be measured which leads to the appropriate design of emergency pressure relief systems.
