This is of great significance for promoting the high-quality development of the hydrogen peroxide industry. 　　In recent years, to increase the production capacity of hydrogen peroxide plants and reduce material consumption, energy consumption, and production costs, domestic manufacturers have widely adopted high-performance working fluids containing TBU components. However, this type of working fluid system tends to experience excessive dispersion inside traditional extraction towers, which can lead to a decrease in the tower’s throughput or even flooding, severely affecting the normal and safe operation of the production facility. Moreover, in traditional tray towers, severe liquid-phase backmixing leads to a high water content in the raffinate. 　　“To address these issues, the hydrogen peroxide R&D and production center mobilized its staff to take a two-pronged approach, focusing on developing new sieve plate technologies from both the process and equipment perspective, in order to solve the problems of material accumulation and water carryover in the extraction towers. ”Zhao Xiaodong explained. 　　It is understood that this technology introduces a new type of composite packing layer into traditional sieve plate towers, thereby enabling effective control over the dispersion of the working fluid within the extraction tower. This reduces excessive dispersion and emulsification of the working fluid inside the tower, thus significantly lowering the risk of material accumulation.
