Introduction

Technology Introduction

The process of diluted hydrogen peroxide unit adopts the complete process technology of fixed bed anthraquinone process. While the concentration unit uses falling film evaporation technology.

Technical Features

Process: new fixed bed palladium catalyst with high activity and high selectivity. High hydrogenation efficiency and low consumption for raw materials.

Equipment: The reflux mixed oxidation tower increases the oxidation yield to over 98%; The application of optimized extraction tower structure and efficient oil-water separation technology reduces the volume of the extraction tower by 20%.

Energy consumption: oxidation operation temperature is reduced, and the energy consumption of air compressor is reduced by 20%. Falling film distillation technology, with an effective temperature difference of ≤ 8-10 ℃ in the evaporator, reduces unit consumption while saving steam consumption.
