REMOVAL OF NON-AROMATIC IMPURITIES FROM A NITRATION PROCESS |
摘要 |
A method and apparatus for removing non-aromatic impurities from non-nitrated aromatic reactant in a nitration production process, in which process an aromatic reactant is nitrated (100) to produce a nitrated aromatic product using a molar excess of the aromatic reactant, and non-nitrated aromatic reactant is recovered (102) from the produced nitrated aromatic product and is recycled (104) for use in the nitration production process. A portion of the removed excess non-nitrated aromatic reactant is diverted (106) and subjected to nitration (108). The nitrated stream may be further processed by separating out the spent acids (110) and the non-aromatic impurities (116). These streams may be sent (114, 118) to a suitable location in the nitration production train. |
