Renewable Energy Solutions: Degassing Process

Case Summary:

Renewable energy is paving the way for a sustainable future. While the benefits of transitioning to renewable energy are clear, one of the most frequently discussed challenges is the inconsistency in energy supply. This issue is effectively addressed by energy storage systems, which store power for times when it is less readily available.

Recently, we were approached to assist in developing an automated filling solution that not only measures and dispenses electrolyte solutions but also degases the material. We were excited to design a fluid dispensing solution tailored to their specific needs.

The Problem: Handling the Material

Material compatibility played a crucial role in this project, as the electrolyte used was highly reactive. When exposed to moisture in the air, it triggered an exothermic reaction, causing the material to become extremely hot. Safety was a top priority for the manufacturer, as contact with the material could result in serious burns. Ensuring safe handling and containment of the material throughout the dispensing process was essential to the project’s success.

Degassing: No Air, No Problem

Our system employs dual pressure pots, which are ideal for handling lower viscosity materials and are available in stainless steel, a compatible option for this application. The first tank facilitates the degassing process, while the second tank stores the prepared material before dispensing. Degassing involves placing the material under vacuum pressure to remove all dissolved gases, and for this specific application, the material is held under vacuum for one minute.

To pressurize the degas tank, nitrogen gas is used instead of compressed air, as the material’s reactive nature could trigger an exothermic reaction if exposed to air. Nitrogen ensures both the necessary pressure and a completely airless dispensing system, providing a safe and efficient process for handling the material.

Dispensing: Customized Precision

During the degassing process in the first tank, the second tank continues to dispense material to the system, with an ultrasonic flow sensor monitoring the volume. Once the correct amount of material has passed through the flow sensor, a valve at the end of the arm tooling closes to prevent any excess from being dispensed. Our battery filling system works in conjunction with integrator-designed tooling to fill the energy storage compartments. When the dispensing process is complete and the material level in the second tank is low, the system is alerted and ready for replenishment.

At this point, the valve between the dispense tank and the flow sensor closes, and the valve between the two tanks opens. Additional nitrogen is then pumped into the degassing tank to transfer the material into the dispense tank. Once the transfer is complete, the connecting valve shuts, and the degassing process in the first tank resumes, restarting the cycle.

End Result: Renewable Energy Solutions

Our system provided the end user with a streamlined process, ensuring their material was handled safely and dispensed with precision. As the demand for renewable energy continues to grow, so does the need for innovative solutions. GP Reeves is committed to delivering custom dispensing systems tailored to your production needs.
