Technology Unit

: Plug-Flow Nitration Reactor
: Noram Mononitrobenzene
Short Name: Nitrator
Description: A Plug Flow Nitration Reactor receives a Stream of Mixed Acid in provenance from the Acid Mixer, and a second Reactant Stream of Benzene. The Benzene is fed in a stoichiometric excess of 6 to 8%, relative to the Nitric Acid. The Benzene and Mixed Acid are allowed to react while moving through the Nitrator, under conditions where it is continually or periodically mixed, until the Reaction is complete, which takes about 300 seconds. The mode of operation of the Process is to run with a Mixed Acid temperature of 80°C or lower. Given that Benzene boils at 80.1°C at atmospheric conditions, the suggested mode of operation has the advantage of allowing the Process running at essentially atmospheric pressure through the length of the reactor. The Reaction Fluids exiting the Nitrator are sent to a Separator.
