1. Evaluation of thermal decomposition hazards

Self-ignition and self-decomposition mechanism of unstable chemicals are studied by use of adiabatic calorimetry (ARC and SIT) and thermal analysis such as DTA, DSC, TG and TG-GCMS. Experiment name GC-MS for the study of thermal decomposition. Apparatus for the thermal analysis of exothermic reactions. Click on the image to view a larger version.

2. Prevention of gaseous explosions

For the prevention of gaseous explosions, studies are conducted that would limit conditions that might initiate or lead to explosion; maximum pressures and other explosion characteristics, such as the mechanisms of gaseous detonation and explosions of gas-dust mixtures, are studied. Investigations are also conducted on such protective methods as flame-quenching devices and explosion suppression. Experiment name Laboratory for the study of the explosion properties of chemicals subjected to high temperatures and pressure. Click on the image to view a larger version.

3. Prevention of the ignition and explosion of dusts

For the safe handling of dust, studies are conducted to determine the explosion characteristics, explosion limits, fire spread over dust layer and ignition temperature of various kinds of dust particles. Experiment name Twenty-liter spherical chamber for testing dust explosions. Particle image velocimetry for the study of the propagation of dust flame. Click on the image to view a larger version.

4. Prevention of runaway reactions in chemical processes

Out-of-control exothermic and hazardous reactions are studied to find solutions to hazardous conditions. Computers are used to verify the findings in accidents and to simulate analogies of possible accidents. Experiment name Labo-scale reactor for the study of hazardous reactions. Plant simulator. Batch plant for verification experiments. Click on the image to view a larger version.
