3、Typical cases Frozen brine flow reactor to reduce event tree analysis
The reaction is exothermic, therefore in the jacketed reactor into the frozen brine to remove heat of reaction。If frozen brine flow rate reduce, can make the reactor temperature rise, reaction speed, so that the reaction is out of control。There are installed in the reactor a temperature measurement control system, and with the frozen brine inlet valve connection, according to the temperature control of frozen brine flow rate。
