Our Solutions: Testing

Reaction Calorimetry (RC)

Calorimetry

Our UK laboratory generates thermal screening and reaction calorimetry test data for your hazardous materials or reactions. The Reaction Calorimetry Tool (RC) is used to accurately detect and identify potential reactive chemical hazards in processes.

Data from Reaction Calorimetry allows for accurate assessment of Chemical Reaction Hazards for a desired chemical reaction process. The outputs allow for the adequate design of process safety systems to take your process from lab or pilot plant scale to full production; with the confidence that the process has been assessed for potential hazards.

The Sigma-HSE Advantage

Sigma-HSE is your single solution provider for a full range of thermal screening and calorimetry testing.

Frequently asked questions

Reaction Calorimetry is an industry standard tool for assessing Chemical Reaction Hazards for process scale-up. Method bespoke to the reaction under study.

Each test involves a bespoke developed method depending on the specific requirements of the chemical reaction to be studied.

The Reaction Calorimetry test consists of a well-instrumented apparatus with adaptable peripheral measurement and processing instruments. The reaction vessel holds modest volumes of material (~300 ml) allowing for highly representative mixtures of bulk reactions, and can study the accurate heat of reactions and kinetics for reagent additions. Reactions are performed under isothermal conditions, and by use of well calibrated equipment the heats of reactions are determined.

Either Heat-Flow-Calorimetry or Power Compensated Calorimetry methods can be used to detect temperature rises in the reaction mixture, and the mode is selected to which best suites the reaction to be studied.

The selection of different operational modes depends on material viscosities, exothermic magnitude and phase mixtures. Typical data outputs can include the following:

  • Heat of reaction
  • Heat of mixing/addition
  • Total adiabatic temperature rise
  • Gas generation quantification
  • Tempering temperature
  • Reaction kinetics information

 

Data from Reaction Calorimetry allows for accurate assessment of Chemical Reaction Hazards for a desired chemical reaction process.

The outputs allow for the adequate design of process safety systems to take your process from lab or pilot plant scale to full production; with the confidence that the process has been assessed for potential hazards.

How to get your materials tested

Receive quick and accurate ARSST testing data in just a few simple steps

Contact us

Get in touch with one of our experts so we can learn more about your specific process, unit operations and testing requirements. We'll then generate and send you a customised quote.

Prepare & ship

Prepare your samples including Material Safety Data Sheets where applicable, and ship them to our UK laboratory.

Thermal Screening, Analysis & Reports

Once we've received your samples, we'll begin testing, measuring and analysing. We'll then create and send you a custom in-depth report detailing the potentially hazardous properties of your materials.

Post-Project Support

If you need support after receiving your report, our after-project support team will be on hand to assist you with any questions you may have about your materials. We can also aid you in your understanding of what hazard prevention measures will be most suitable for your processes.

We also undertake the following thermal screening and calorimetry tests to simulate full scale process, and process upset conditions. ​

Please contact us if you have any bespoke combustible dust or powder testing requirements, or if you require consultancy services related to powder and combustible dust explosion safety.

Test your materials

Getting your hazardous materials tested is an important step to prevent fires, explosions and other process-related hazards. Get in touch to learn more about how we can assist you in keeping your process plant and unit operations safe from the risks of thermal runaway.
