|PLINKE has developed a proprietary process for Adiabatic Nitration of Benzene to Nitrobenzene (NB). With our extensive experience in re-concentration of NB spent acid, we offer an integrated unit with both nitration and spent acid processing. The result is a very energy efficient overall process with excellent NB product quality and highly reliable Sulfuric Acid recovery process. The energy released during the chemical reaction of Benzene to Nitrobenzene is kept within the process. PLINKE's reactor is highly efficient and its small size results in small plot plan requirements and low investment cost. PLINKE offers the complete range of nitration, separation and washing steps as well as effluent gas handling.|
The PLINKE adiabatic NB process consists of major operating steps:
- Product separation
- Sulfuric Acid reconcentration
- Benzene recovery
- Waste gas treatment
Diluted Nitric Acid of any concentration between 50 % and 68 % HNO3 can be used.
