Technology Introduction:

There are Several Methods for hydrogen peroxide Production , Among Them The AO (Auto-Oxidation) Process IS The MOST the prevailing One. The In the this Process, 2-alkyl Anthraquinone IS Mixed with Organic Solvent to the 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 Fixed Bed Process and the Reactor INTO Fluidized Bed the Reactor Process. SL Tec the Provides both-Processes. at The Fixed Bed Process the Reactor TEC SL  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.Advanced DCS control system, SIS safety system and industrial video monitoring system are set up. The optimal control, alarm and safety interlocking of various process parameters in the hydrogen peroxide production process are realized. Implement video surveillance for key point control points and key positions. Ultimately, the entire system is stable, high-yield, low-cost and safe.

2.Concentration adopts the world's most advanced falling film distillation technology to make the residence time of hydrogen peroxide solution in the falling film evaporator short to avoid the decomposition of hydrogen peroxide; in addition, the evaporator uses low pressure saturated steam to make the effective temperature difference ≦8~10 °C, which saves steam consumption while reducing unit consumption.

3.The Fenton oxidation method + biochemical treatment sewage technology has been successfully applied, so that the sewage of the hydrogen peroxide device is completely discharged after being treated.

4.System-wide air release for centralized recovery and disposal of the system. The unorganized exhaust gas is recovered and there is no odor on site. It not only reduces solvent consumption, but also improves the working environment and meets the requirements of occupational health and environmental protection acceptance standards.

5.The post-treatment drying column uses high-efficiency reaction and separation of filler packing. Solved the problem of causing alkali in the drying column. The burden on the subsequent activated alumina bed is alleviated. Reduced consumption of activated alumina. At the same time, it ensures the long-term operation of the system.
