The nitrogen pressure required for adsorbent filtration and color remediation can vary depending on the specific equipment, setup, and the type of media you are using. It's essential to follow the manufacturer's recommendations for your particular closed-loop extraction system and adsorbent filtration equipment.
In general, nitrogen gas can be used to apply pressure to assist in pushing the solvent through the adsorbent media, enhancing the filtration and color remediation process. The pressure you need may vary based on factors such as the viscosity of the solvent, the flow rate, the type of adsorbent media, and the desired results.
It's recommended to start with a moderate nitrogen pressure and gradually increase it while monitoring the flow rate and effectiveness of the process. Generally, pressures in the range of 20 to 50 psi (pounds per square inch) are commonly used for adsorbent filtration and color remediation. However, this pressure range can be adjusted based on your specific equipment and requirements.
Keep in mind that using too high of a pressure can potentially cause channeling, uneven flow, and limited retention through the adsorbent media, affecting the quality of the filtration process. It's essential to strike a balance between achieving effective filtration and avoiding excessive pressure that could lead to inefficient results or potential safety risks. It's best to perform small-scale tests before scaling up to ensure optimal results and start off slowly when using nitrogen pressure for adsorbent filtration and color remediation.
