Systematic process hazard assessment of three kinds of solid organic peroxides with kinetic analysis and heat transfer equilibrium

摘要

Organic peroxide (OP) has been applied in the industry for at least 40 years. Driven by significant investments in today’s high-profile energy, petrochemical, and polymer industries, the market and applications of OPs are expanding rapidly. However, the self-reactive nature has led to continuous research work on this topic. Nevertheless, tremendous progress has been made in hazard analysis, which has improved existing protocols or led to the discovery of new safety methods. OPs still cause related chemical hazards, and the limitations related to process hazards remain to be resolved. There is a lack of comprehensive systematic analysis of the process hazards of a wide variety of OPs. Different OPs, namely BPO, LPO, and the emerging OP, HTP-65W, were selected for investigation with several calorimetry techniques based on thermokinetic and heat transfer models. Determination methods have a crucial role in an operator for obtaining a systematic understanding of hazard properties under different process conditions, which is related to avoiding the occurrence of process disasters. For example, LPO has a shorter TMRad and TCL (<1 min) than BPO and HTP-65W, indicating that LPO can be classified as an obvious hazardous material. Moreover, SADT <25 °C can be used for evaluating LPO’s cooling system efficiency.
