Thermal hazard assessments in process industries often require calorimetry and kinetic modeling. These techniques are illustrated using examples of inhibited 4-vinylbenzyl chloride (VBC) self-polymerization and di-4-methylbenzoyl peroxide (MeBPO) thermal stability. The polymerization kinetics of inhibited VBC were studied using isothermal and non-isothermal calorimetry. A thermokinetic model was developed using calorimetry data and this model was coupled with a heat balance to predict the consequence of a commonly encountered plant scenario, loss of active cooling to a storage tank. Isothermal differential scanning calorimetry (DSC) and microcalorimetry (using a TAM IV microcalorimeter) were also applied to analyze the thermal decomposition of MeBPO desensitized with silicone oil (50% weight/weight). The thermokinetic parameters and thermal stability were evaluated. MeBPO decomposes in two exothermic reactions, and the total heat of decomposition was determined to be 658.8 J/g of sample. The thermal decomposition of MeBPO was described by a model of two parallel reactions, the first leading to 4,4′-dimethylbiphenyl and the second to p-methylbenzyl p-toluate. The results can be applied for emergency relief system design and for emergency rescue strategies during an upset or accident.
