How To Produce Industrial Urea Solution?

Use high purity urea and deionized water as the main raw materials to produce industrial urea solution (usually called AdBlue or DEF, i.e. diesel exhaust treatment fluid).

1. Production process of industrial urea solution

1.1 Raw material preparation

Ensure that the urea used is of high purity, and the purity is generally required to meet the agricultural urea standard (such as German DIN 50018 or ISO 22241 standard).

Prepare deionized water to ensure that the water quality meets the production standard of industrial urea solution for industrial vehicles, and the resistivity is usually required to reach 15 MΩ·cm or above.

1.2 Dissolution process

Add high purity urea to deionized water in a certain proportion for dissolution. The standard concentration of automotive urea solution is usually 32.5% (mass percentage concentration) of urea aqueous solution.

1.3 Mixing and stirring

Mix urea and deionized water at room temperature, and stir thoroughly using a stainless steel urea solution stirring tank to ensure that the urea is completely dissolved.

1.4 Quality control

During the mixing process, use a refractometer or refractometer to detect the concentration of the solution to ensure that it meets the standard requirements.

Detect the pH value of the solution. The pH value of the general automotive urea solution is controlled between 8.5-10.5.

1.5 Filtration and purification

Filter the mixed solution through a filter to remove possible insoluble matter or impurities to ensure the clarity of the urea solution.

2. What are the main manufacturing machines required for industrial automotive urea solution?

2.1 Industrial stainless steel liquid mixing tank: The production of industrial automotive urea solution usually requires the use of high quality stainless steel liquid mixing tanks. The tank body of this mixing tank has excellent corrosion resistance and can ensure the purity of the solution; it is equipped with heating and temperature control functions to ensure that urea dissolves evenly at different temperatures; built-in stirring system to achieve efficient mixing; at the same time, the tank body design focuses on operational convenience and cleaning and maintenance, which can meet the efficiency and quality requirements of large scale production.

2.2 Industrial secondary reverse osmosis (RO) water treatment machinery: The production of industrial automotive urea solution requires the use of efficient and stable industrial secondary reverse osmosis (RO) water treatment machine with EDI. This equipment has the characteristics of high desalination rate and high water output, and can remove impurities such as dissolved solids, microorganisms, and organic matter in the water, ensuring the provision of deionized water with high resistivity and purity that meets the standards, meeting the strict requirements of automotive urea solution for water quality.

2.3  Automatic urea solution filling machine: In the production process of industrial automotive urea solution, automatic urea solution filling machinery is usually required. In order to adapt to different production scales and needs, IMMAY's automatic urea solution filling machine can customize the equipment according to your needs, such as the number of filling heads and filling speed. For large scale production, you can choose a multi-filling nozzles configuration to achieve high output; for small batch automotive urea solution production lines, you can choose a single filling head configuration to provide greater flexibility and meet your production goals.
