“…For the liquid monomer, VBC, each sample was weighed and sealed in a gold-plated high-pressure crucible (30 μL) under an air headspace, which can sustain a pressure of 15 MPa. Gold-plated high-pressure crucibles have been validated to be very useful for thermal investigation to support loss prevention analysis . The temperature scanning rates selected for the temperature-programmed ramp were 0.5, 1, 2, 4, and 8 °C/min.…”

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% w/w). 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.

Ethanolamine is a critical chemical for petrochemical enterprises. When corrosion occurs in pipelines, equipment, and containers in petrochemical enterprises, minute amounts of metal ions are released. In this study, the thermal decomposition and nonisothermal kinetics of monoethanolamine (MEA) and MEA mixed with copper and zinc ions were analyzed using thermogravimetry (TG) and differential scanning calorimetry (DSC). The TG tests revealed that MEA mixed with copper (II) and zinc (II) began thermal decomposition at 75.2 and 60.3 °C, respectively, whereas pure MEA began thermal decomposition at 89.7 °C. Two exothermic peaks were observed in the DSC curves for MEA mixed with copper (II) and zinc (II), and thermokinetic parameters were obtained from DSC data. The apparent activation energy ( E a ) of each stage was calculated using several nonisothermal kinetic methods, namely the ASTM E698, Kissinger–Akahira–Sunose, Starink, and Flynn–Wall–Ozawa methods. The E a of pure MEA was 28.7 ± 2.5 kJ/mol, whereas that of the copper and zinc mixtures were 80.5 ± 1.1 and 46.8 ±1.7 kJ/mol, respectively. The results can be used to improve the intrinsic safety of storage tanks and petrochemical plants.

“…Its general formula is R1-O-O-R2. However, the O-O bond is relatively weak, making organic peroxides extremely unstable and likely to decompose due to external factors such as high temperature, friction, and impact [3,4]. If the heat generated by thermal decomposition is not removed in time, it will trigger a number of uncontrollable chain reactions, eventually leading to fire and explosion accidents.…”

Tert-butyl peroxy-3,5,5-trimethylhexanoate (TBPTMH), a liquid ester organic peroxide, is commonly used as an initiator for polymerization reactions. During the production process, TBPTMH may be exposed to acids and alkali, which may have different effects on its thermal hazard, so it is necessary to carry out a study on the thermal hazard of TBPTMH mixed with acids and alkali. In this paper, the effects of H2SO4 and NaOH on the thermal decomposition of TBPTMH were investigated by differential scanning calorimetry (DSC) and adiabatic calorimetry (Phi-TEC II). The “kinetic triple factors” were calculated by thermodynamic analysis. The results show that the three Ea are 132.49, 116.36, and 118.24 kJ/mol, respectively; thus, the addition of H2SO4 and NaOH increased the thermal hazard of TBPTMH. In addition, the characteristic parameters (time to maximum rate under adiabatic conditions, self-accelerated decomposition temperature) of its thermal decomposition were determined, and the control temperature (45, 40, and 40 °C) of TBPTMH under the action of acid-alkali were further received. This work is expected to provide some guidance for the safe storage, handling, production, and transportation of TBPTMH in the process industry.
