The hydrogen peroxide concentration unit at Orchid New Materials Branch was successfully put into operation. Author/Source: Orchid News Date: 2020-09-02 Clicks: 70. A few days ago, the hydrogen peroxide concentration unit at this branch managed to produce hydrogen peroxide with a concentration of 50%, meeting the required standards. This marks the successful restart of this unit after three years, thereby addressing the difficulties associated with wastewater treatment in the caprolactam production process and reducing overall costs, with significant positive effects as a result. The company’s hydrogen peroxide concentration unit utilizes the principle of low-temperature negative-pressure distillation to concentrate industrial-grade hydrogen peroxide with a concentration of 27.5% into technical-grade product with a hydrogen peroxide content of 50%, as well as chemical-grade product with a 40% concentration and high purity as well as low total carbon content. This process offers advantages in terms of no waste solids or gases generated, and the distillate can be recycled. Furthermore, according to actual production requirements, hydrogen peroxide products with concentrations ranging from 30% to 35% can also be formulated, allowing for greater flexibility in adjustment. When used as a raw material in the caprolactam plant, it can reduce the wastewater discharge from the plant by about 5 m3/h, **reducing the company’s costs associated with wastewater treatment and thereby lowering overall expenses.
