Materials Preparation: A certain amount of raw material wax is poured into a preheated tank, where it is decontaminated, dehydrated, and heated to 120℃ for insulation. Catalyst potassium salts and manganese salts are added to the dissolution tank at a rate of 1.5-2‰ based on the feed amount, and soda ash at a rate of 0.3-0.8‰. After dissolving with water, they are set aside. Approximately 50% of the material is then used to make a 25-30% concentration alkali solution for later use.
      2. Preparation of Oxidized Wax: Transfer the preheated material from the preheating tank into the oxidation tower, simultaneously supplying air at a rate of 40 cubic meters per ton per hour and providing heat. Inject a mixture of the prepared catalyst and sodium carbonate solution into the tower. Once the material temperature inside the tower reaches 160±2°C, initiate the process and maintain for 0.5 hours. Increase the air supply to 50 cubic meters per ton per hour, lower the temperature to 150±2°C, and begin the activation. After two hours, reduce the tower material temperature to 120-130°C and start the oxidation. Simultaneously, increase the air supply to 60 cubic meters per ton per hour without changing the temperature. Continue oxidation for 12 hours, then raise the air supply to 80 cubic meters per ton per hour without changing the temperature. After activation, start testing the acid value. When the acid value of the material in the oxidation tower reaches 80-85 mgKOH/g, the oxidation is complete. Upon completion of oxidation, stop heating and cool the tower material to 120°C, while reducing the air supply to 40 cubic meters per ton per hour. Begin discharging the material from the tower into a saponification tank that has 30-40% of its capacity filled with 75°C hot water. Simultaneously, evenly inject the oil-soluble acid generated from the reaction into the saponification tank.
      Saponification
      (Washing: Adjust the temperature of the oxidized wax in the saponification tank to around 85°C, and use steam or air to agitate the material until it is in a frothing state. When the material temperature in the saponification tank drops below 85°C, use direct steam to stir. When the material temperature exceeds 85°C, switch to air stirring. Stir for at least 40 minutes. After stirring stops, maintain the temperature at 85-90°C for sedimentation. After 30 minutes of sedimentation, drain the wastewater and intermediate layer from the bottom of the saponification tank. Test the acid value of the oxidized wax after washing until the wastewater pH value is slightly acidic. If not up to standard, repeat the washing process.)
      (2). Saponification: Qualified oxidized wax from the washing tank is heated to 95-100°C with steam, while adding approximately 35% of the material in water. Under boiling conditions, the prepared alkali solution is added to the oxidized wax. The amount of alkali added is calculated as follows: Alkali per ton of oxidized wax = Acid Value × 1.8 × 0.71 × 1.03 (excess alkali) ÷ Concentration ÷ 1000. After sufficient alkali is added, saponify for one hour, then continue with a second saponification cycle for more than one hour. After saponification, check the pH value to be around 13; if not, continue to add alkali for saponification.
      (3). Separation: After saponification, the material in the saponification tank is kept warm and settled for at least 3 hours. The soap liquid is then transferred to the soap liquid storage tank, and after a static period of over 24 hours, it is moved to the next process.
      4. Refining: Qualified soap liquid in the storage tank is pumped into the tube furnace using a pressure pump, adjusting the feed and fuel quantities. When the moisture content of the material is around 30%, it is transferred to the refining tank, becoming an intermediate product of paraffin wax soap. After inspection, the free alkali content and moisture are adjusted to meet the standard requirements. The material in the refining tank, upon passing inspection, becomes finished product and is then transferred to the finished product tank for measurement and packaging.
