Reactive Pressure Relief System Design

Safe design of reaction containment and venting systems depends on a thorough understanding of chemical reactivity hazards and thermokinetics. ioKinetic offers a three step approach.

 

Step 1: Chemical reactivity evaluation
  • Conduct a closed small-scale adiabatic test (e.g. ARC®, APTACTM)
Step 2: Develop a kinetic model that simulates the adiabatic test
  • Define reaction stoichiometry using measured vapor-liquid equilibrium
  • Define a reaction model
Step 3: Predict behavior in the full-scale vessel
  • Use the developed stoichiometry and reaction model
  • Simulate the actual full-scale vessel
  • Complete process optimization, pressure relief system design (including inlet and outlet piping)

 

We have carried out large-scale hazard tests to benchmark our approach and verify the magnitude of the hazard in commercial scale systems. For such tests, we develop a test plan, oversee the field testing, interpret the test results, and prepare a summary report.

We use software tools that are the industry standard for performing reactive system pressure relief design. The AIChE Design Institute for Emergency Relief Systems (DIERS) Users Group selected ioMosaic Corporation’s Process Safety Office™ SuperChems™ component as their replacement for the SAFIRE computer code. SuperChems™ has been the subject of many publications and is used successfully worldwide by major chemical companies.
