| titleOfInvention | The oxidized tail gas processing system and method for the raw materials used aminobenzoic acid of EHA, EDB |
| abstract | The present invention discloses the oxidized tail gas processing system and method for the raw materials used aminobenzoic acid of a kind of EHA, EDB, the processing system includes alkali liquor storage tank, alkali adsorption tower, acidifying kettle, filter, distillation still, crystallization kettle, centrifuge and the drier being sequentially connected by pipeline, valve, pump, the alkali liquor storage tank, alkali adsorption tower, acidifying kettle, distillation still, crystallization kettle top are equipped with charging aperture, bottom is provided with discharging opening, the distillation still is connected with condenser, and the condensed vapor of condenser enters hopper by pipeline；The processing method recycles soda ash solution 34 times, distilled after the sodium nitrate in solution reaches finite concentration, energy consumption can be reduced to original 1/3rd, utilization is repeated after collecting water vapor condensation, concentrated nitric acid sodium solution after distillation is by centrifugal drying after crystallisation by cooling, and content may be up to 99%, and the processing method reduces the use of energy consumption and water, increase output simultaneously, reduce the pollution of tail gas and abraum salt to environment. |
