Olefin waste alkali solution

Common methods for treating alkali waste liquid from olefins include neutralization, evaporation, drying, incineration, and resource utilization. The specific method to choose depends on the composition and concentration of the waste alkaline solution. For example: 1. Neutralization method: Acids are used to neutralize waste alkaline solutions, producing salts and water; the resulting salts are then processed or utilized. 2. Evaporation method: Reusable sodium hydroxide solution is separated through evaporation concentration. 3. Drying method: The waste alkaline solution is concentrated and then dried to produce solid alkali or alkali-containing solids, which can be used as raw materials or fuel. 4. Incineration method: For waste alkaline solutions containing organic substances, high-temperature incineration can be used to destroy these organic substances and reduce pollution. 5. Resource utilization method: Recycling waste alkaline solutions as raw materials for production, such as reusing them in the manufacturing process or as raw materials for other chemical products. Before treatment, the waste alkaline solution should be thoroughly analyzed to ensure that the method chosen not only enables efficient treatment of the waste but also minimizes its impact on the environment. .

The alkali waste from olefins is treated into sodium salts using the wet medium-pressure oxidation method, and then sent to a wastewater treatment plant.
