Kinetic-Free Safe Optimization of a Semibatch Runaway ...

In this work the general Ψ number criterion for the safe operation of semibatch runaway reactions has been applied to the optimization of a nitration process of primary importance in the agrochemical industry, that is the nitration through mixed acids of 4-chloro benzotrifluoride to produce a widely employed class of fluorinated herbicides. Such a reaction, as is the case for almost all the ...

Part 11 - Welcome to Reactor Lab! - Reactor Lab

A semi-batch reactor in which a reactant is fed during the reaction is also called a fed-batch reactor. One reason to operate a reactor this way is to control heat release and the temperature for a highly exothermic reaction. R. K. Herz, [email protected], Part 11, p. 5 of 10

Mar 01, 2010  The typical behaviour of this semibatch process can be shown in Fig. 1 where reactor and jacket temperatures, conversion and divergence are depicted for two extreme simulated cases: a non-runaway (left) and a runaway (right). As can be seen in the first simulation div is always negative, whereas for the runaway case, div becomes positive during a certain period.
