Hydrogen Peroxide Plant (Fixed Bed Process)

Agent Technology and Plants

Technology Introduction:

There are several methods for hydrogen peroxide production, among them the AO(auto-oxidation) process is the most prevailing one. In this process, 2-alkyl anthraquinone is mixed with organic solvent to make up the working solution, which is hydrogenated in presence of catalyst, and the resulting is oxidized by air (or oxygen) in counter-current way before being extracted, regenrated, purified and enriched to get commercial hydrogen peroxideproduct. Depending upon the different reactor type in the hydrogenation unit, AO process is further divided into Fixed Bed Reactor Process and Fluidized Bed Reactor Process. SL Tec provides both processes. The Fixed Bed Reactor Process SL TEC provides is the most advanced technology in China. It employs heavy aromatics-TBU-TOP tertiary solvent in the working solution and alumina-supported Pd catalyst with high activity.

Technical Features:

Compared to the other Fixed Bed Ractor Process prevailing in China, the technology offered by SL TEC has advantages as below:

1. The working solution has higher solubility of anthrahydroquinone and anthraquinone, and can ensure the hydrogen peroxide plant's normal running with the process productivity as the WS (working solution) capacity over 9.5g/L.

2. The catalyst has higher activity and better selectivity, with the unit production capability of 6.5 kg/ kg of 100% hydrogen peroxide.

3. The working solution has higher partition coeficient, which makes it easier to produce high concentration hydrogen peroxide in the extraction column, meanwhile the raffinate phase is lessened to increase the operation safety.

4. With this new kind working solution, the oxidation time under same conditions is increased to more than 97%.

5. Due to the obvious lower consumption rate, the production cost of per ton of industrial grade product can be saved by 10-20%.

6. After revamping, the capacity of the plant using the traditional process can be increased by 30-50%, which saves the investment and especially favorable for the old plant revamping.
