TN270 – Pressure evaluation during reaction Private content

Many organic materials used in chemical reactions exhibit an hazardous behavior when heated. Their composition may produce a large amount of vapor and increase very highly the pressure in the reactor. So the pressure, especially its evolution during the reaction, has to be well known in order to design correctly the reactor and the safety devices to prevent any risk of explosion and destruction of the reactor. Chemical plants are especially interested in this pressure control during reaction or storage.
SETARAM has designed a calorimetric high pressure vessel linked with a pressure gauge in order to evaluate in the same time the pressure evolved during the reaction and to follow the heat dissipated. Both data can be used to calculated the reactor dimensions and to evaluate the risk of decomposition.
