Hydrogen Peroxide Generator - High Efficiency Hydrogenation Reactor, Plc Controlled Automation, 27.5%, 35%, 50% Concentrations, Reduced Waste Gas And Wastewater Treatment

In the anthraquinone process to produce hydrogen peroxide, it is normally adopted Pd catalyst, fixed bed and hydrogenation process. In the presence of Pd catalyst, the alkyl anthraquinone dissolved in the organic solvent is hydrogenated to produce the alkyl anthra-hydroquinone, which is oxidized to get the hydrogen peroxide under given reaction conditions eventually. Meanwhile the alkyl anthra-hydroquinone is converted into alkyl anthraquinone and the stream of working solution contained H2O2. The resulting stream of working solution is fed to the extraction column for extraction by using deminaralized water as extracting agent in a counter-current flow to produce H2O2, which is purified to form the finished product-H2O2 and it will be delivered to the storage tank. The solution of alkyl anthraquinone after treatment returns to the hydrogenation section for reuse.

Technical features

The new structure of hydrogenation reactor that possesses high efficiency of hydrogenation and will saves the amount of catalyst as well;
The high efficient oxidation column increases the yield by 3%;
The active carbon fiber adsorber can adsorb the aromatics in the off-gas so as to reduce the consumption of aromatics and environment pollution;
The new type of trays structure of extraction column can produce 35% H2O2 directly;
The volume of post treatment equipment is reduced one third after modification;
It is less land occupied and investment-saving;
This facility can produce different concentration products of 27.5%, 35% and 50%.
High automation by adopting DCS system;
Less waste gas and the wastewater is treated with the process of Fenton I. E. The way of H2O2 catalyzed oxidizing flocculation to realize the clean production.
