(188as) Risk Assessment of Runaway Reaction In a Vinyl Acetate Polymerization Process

Most of the chemical reactions performed in the chemical industry are exothermic, meaning that thermal energy is released during the reaction. In chemical industry, most concerns are focused on the thermal hazards such as runaway reactions and thermal stabilities, which are motley governed by thermodynamics and reaction kinetics of the mixed materials. Lack of understanding of the process chemistry and thermodynamics are the major reasons that can be lead to thermal runaway reaction in the chemical reaction For this reason, the heat of reaction is one of the key data, which allow assessment of the risks linked to a chemical reaction at the industrial scale. The risk assessment of thermal behavior and runaway reaction cased by an exothermic batch process in manufacture of the vinyl acetate resin are described in the present paper. The experiments were performed in the Mettler's multimax reactor system and reaction calorimeter. The aim of the study was to evaluate the results of different calorimeters in terms of reliability for practical applications of accident examination. We suggested that we should propose reaction hazard information of raw materials safe precautions with operating conditions in the vinyl acetate polymerization process through this study.
