Technology

Adiabatic Nitration MNB Plants by MEISSNER are characterized by the application of Tube Reactors, which minimize the Formation of By-Products (Nitrophenols, Picric Acid and Dinitrobenzene) by optimum Reactant Intermixing and negligible Back Mixing inside the Tube Reactor. Due to the Adiabatic Technology, the Reconcentration of the Sulfuric Acid accruing after separation of the MNB takes place directly in the Plant. The Crude Mononitrobenzene is automatically fed to the Washing Section. In the subsequent Stripping Unit the Residual Benzene still contained in the Purified Mononitrobenzene is separated by Means of Steam and returned into the Process.
