How to Make DEF Fluid – The Process Explained

Making Diesel Exhaust Fluid (DEF) is not a complicated process, and the chemicals involved are readily available. You only require three primary ingredients; namely, urea, deionized water, and a catalyst. Urea, a key component, is readily available and used in fertilizers, animal feed, and pharmaceuticals. Deionized water refers to water with minerals and salts removed, usually achieved through an ion exchange process or reverse osmosis. The catalyst, consisting of a small quantity of additives, mainly reduces the freezing point of the DEF fluid, making it appropriate for use in cold weather conditions or environments.

Step-by-Step Guide On How to Make DEF Fluid

Step 1: Gather the Ingredients and Equipment Needed

Before starting the process, ensure that you have all the necessary ingredients and equipment. For the ingredients, you need urea, deionized water, and a catalyst. In terms of equipment, you will need a measuring cup, a scale, a mixing bowl, and a heating element.

Step 2: Weigh and Mix the Urea

Measure the correct amount of urea required, based on the mixture ratio and guidelines set for your specific DEF production. Pour the urea into the mixing bowl and proceed by slowly adding the required amount of deionized water. Allow the mixture to dissolve entirely before stirring.

Step 3: Add the Catalyst

Once the urea has fully dissolved into the deionized water, it is time to add the catalyst. Depending on the specific requirements of your DEF mixture, add the measured amount of catalyst. Stir the mixture thoroughly to ensure that all the components are evenly distributed.

Step 4: Use an Eductor Mixer for Homogenous Blending

An eductor mixer facilitates complete blending of the components and ensures a homogeneous mixture. Build pressure in the mixing tank and allow the eductor to draw of the DEF mixture to be fed back repeatedly into the tank through a recirculation loop. This process will cycle until the mixture achieves a consistent and homogenous blend.

Step 5: Screen the Fluid

Before packaging the DEF fluid, screen it using a screen filter. This helps to remove any debris or solids that could impact the quality of the product and contribute to system malfunction. The screen filters the mixture until it is particle-free and smooth.

Step 6: Quality Check and Package Your DEF Fluid

Once you are confident that the DEF fluid has attained the desired standards, it’s time to begin packaging. DEF fluid is stored in airtight containers to prevent contamination. Standard container sizes range from one gallon jugs (3.78 liters) to 330-gallon totes (1,249 liters).

Step 7: Store Your DEF Fluid Correctly

DEF fluid is highly sensitive and requires proper storage to maintain its quality. Store it at moderate temperatures, preferably between 12℃ to 27℃ (50°F to -86°F). Keep it in a cool, dry place, away from ultraviolet (UV) rays, and ensure it is not exposed to oxygen or moisture.

Step 8: Handle and Label the DEF Fluid Correctly

Always be mindful of handling the DEF fluid with care, following the necessary precautions, and labelling it accurately. As DEF fluid contains non-hazardous chemicals, it must be appropriately classified along with the shipment, ensuring proper shipping documentation and safety guidelines.

Ingredients Needed for DEF Fluid Production

To make DEF fluid industrial or agricultural use, you’ll need to gather all of the necessary ingredients. DEF fluid is composed of three basic elements: high-quality deionized water, automotive-grade urea, and supply and storage containers.

Here are all of the ingredients you’ll need to make DEF fluid:

Deionized Water

The most important ingredient in DEF fluid is deionized water. Even the smallest percentage of impurities in regular water can dramatically affect the water quality. That’s why deionized water should be used for DEF fluid production. Deionization is the process of purifying water by removing flakes and minerals.

Automotive-Grade Urea

Automotive-grade urea is the second essential component that is needed for DEF fluid production. Urea is a compound that is extracted from natural gas and used as a nitrogen fertilizer. It is sold in an automotive grade that is designed solely for DEF fluid manufacturing purposes.

Storage and Supply Containers

You will also need secure and safe storage containers and supply vessels to store and dispense your DEF fluid safely. DEF fluid cannot be stored in containers that were used to hold other chemicals as this may cause cross-contamination.

Mixing and Producing DEF Fluid

Now that you have all of the essential ingredients, it’s time to start creating your DEF fluid. The first step is to determine the quantity you require then mix them in the right ratio (32.5% urea and 67.5% deionized water). A professional DEF mixer should be used to mix the components together accurately.

Here is a table showing example of DEF fluid production in different quantities:

Once you mix the deionized water and automotive grade urea in the right ratio, the next step is to store the solution in DEF containers or supply vessels lined with DEF-grade materials. DEF fluid degrades over time when exposed to air and other contaminants, so it is crucial to ensure that the containers you use are DEF-grade and sealed tightly.

Conclusion

Making DEF fluid is a relatively simple process once you have the right ingredients and equipment. Always ensure that you use the right quality of deionized water and automotive-grade urea as they form the basis of the final product. Keep in mind that DEF fluid is sensitive to air, humidity, and contamination, and store it accordingly in sealed DEF containers that are DEF-grade compliant. Now that you know how to make DEF fluid, you can save money and have peace of mind while using it.
