20LB High Purity USA N-Butane R600 for Extraction - Buy 2 Get 1 Free (Add 3 To Cart) This solvent is instrument-grade and helps produce a higher quality extract through the reduction of mystery oils and contaminants. This N-Butane is colorless, odorless, and clean. Butane is commonly used for butane extractions which occurs in a closed-loop extraction system. Given that butane has a boiling point of 30.2F, it can easily be re-condensed without the use of extreme temperatures. This makes butane the solvent of choice for passive recovery.  Butane tends to yield a more stable extract, as polar terpenes are left behind.  Another benefit to butane for extraction is that Hydrocarbon extraction is often used in large production.  Large amounts of material can be extracted at once, and because these solvents have such low boiling points, they can be distilled from the extract quickly, and without using high temperatures can degrade the product.  These solvents are used for full plant extracts, and post-processing can yield various consistencies.  This makes butane extraction a preferable method.

Food and Beverage Industry: Nitrogen gas is used to dispense draft beer, wine, coffee, and other beverages, creating a foamy head and enhancing the presentation. How Can I Pressure Test My Extractor With Nitrogen? Pressure testing your extractor with nitrogen involves using nitrogen gas to check for leaks, verify the integrity of the equipment, and ensure its safety before performing actual extraction processes. Here's a step-by-step guide on how to pressure test your extractor using nitrogen gas: Materials Needed: Nitrogen gas cylinder with appropriate regulator Pressure gauge PTFE tape (thread seal tape) Bubble solution or soapy water Safety goggles and gloves Wrench or spanner Steps: Preparation: Ensure that the extractor is clean and free from any residual materials. Check all fittings, connections, valves, and joints for signs of damage, wear, or corrosion. Replace any damaged components. Make sure the extractor is properly assembled and closed, including any access ports or lids. Safety Precautions: Wear appropriate safety goggles and gloves to protect your eyes and hands. Work in a well-ventilated area to prevent the buildup of nitrogen gas. Regulator Setup: Attach the nitrogen gas cylinder to the regulator and secure it tightly using a wrench. Set the desired pressure on the regulator according to the recommended pressure for your extractor and testing requirements. Sealing Threads: Apply PTFE tape to the threads of the fittings and connections. This helps create a better seal and prevents leaks. Connect Nitrogen Gas: Connect the regulator outlet to the appropriate inlet or access port on the extractor using a compatible hose or tubing. Pressure Testing: Slowly open the nitrogen gas cylinder valve to allow gas to flow into the extractor. Monitor the pressure gauge and allow the pressure to build up to the desired test pressure. Once the desired pressure is reached, close the cylinder valve to stop the flow of nitrogen gas. Leak Detection: If pressure is not maintained apply a bubble solution or soapy water to all the fittings, joints, and connections. Inspect the extractor for any bubbles forming, indicating potential leaks. Pay close attention to areas where bubbles appear, and tighten or adjust fittings after depressurizing the system as needed to eliminate leaks. Release Pressure: Slowly release the pressure from the extractor by gradually opening the cylinder valve. Once the pressure is completely released, disconnect the nitrogen gas source. Final Inspection: Reapply the bubble solution or soapy water to the connections that were adjusted. Verify that no bubbles form, indicating that leaks have been successfully resolved. Documentation: Keep a record of the pressure test results, including the test pressure and any adjustments made. Repeat if Necessary: If any leaks were detected and resolved, repeat the pressure test to ensure all leaks have been eliminated. Pressure testing your extractor with nitrogen gas helps ensure the safety and integrity of the equipment, minimizing the risk of leaks during actual extraction processes. Always follow proper safety guidelines and manufacturer recommendations when working with nitrogen gas and pressure testing equipment. How Do I Perform A Nitrogen Assisted Extraction? Using nitrogen to inject butane into a closed-loop extraction system requires careful consideration and adherence to safety protocols. Nitrogen gas can be used to pressure test the extraction system, assist in transferring butane throughout the system, and assist in the process of adsorbent filtration/color remediation. Here's a step-by-step guide on how to use nitrogen to inject butane into your closed-loop extraction setup: Materials Needed: Closed-loop extraction system with Pressure Relief Valve Nitrogen gas cylinder with appropriate regulator Pressure gauge Nitrogen-compatible hose or tubing Butane tank Butane-compatible hose or tubing Safety goggles and gloves Wrench or spanner Steps: Safety Precautions: Wear appropriate safety goggles and gloves to protect your eyes and hands. Work in a C1D1 environment to prevent the buildup of flammable gases. Preparation: Ensure that the closed-loop extraction system is clean, properly assembled, and free from any residual materials. Regulator Setup: Attach the nitrogen gas cylinder to the regulator and secure it tightly using a wrench. Set the desired pressure on the regulator based on the recommended pressure for your closed-loop system and extraction process We recommend utilizing 25-50 PSI to perform solvent transfer throughout the system. Nitrogen Line Connection: Connect the regulator outlet to the nitrogen-compatible hose or tubing. Connect the other end of the hose to the vapor port or accessory port to the recovery cylinder of your closed-loop system. Butane Line Connection: Connect the recovery cylinder to the closed-loop system using a butane-compatible hose or tubing. Ensure that the recovery cylinder is securely connected to the system, properly sealed, and grounded. Pressurizing the System: Slowly open the nitrogen gas cylinder valve to allow nitrogen gas to flow into pressurize the recovery cylinder. Monitor the pressure gauge and pressurize the recovery cylinder to the desired pressure for injecting butane. Nitrogen gas is used to create pressure that forces the butane into the system. Injecting Butane: Open the valve on the recovery tank to allow the butane to flow into the material column of the closed-loop system. The pressurized nitrogen gas assists in transferring the butane through the system and into the collection base of the system. Monitoring and Safety: Carefully monitor the pressure levels on both the nitrogen gas cylinder and the recovery cylinder. Venting: Once the injection and extraction processes are complete, close the valves on both the nitrogen gas cylinder and the recovery tank. Prior to applying heat to your collection base and starting your solvent recovery procedure first slowly vent the nitrogen from the collection base directly into the ventilation system of your C1D1 Booth.  Monitor the pressure gauge and sight glass of the collection base closely. Slowly and incrementally vent the nitrogen from the system until the solution begins to boil this is an indication that the nitrogen filling the headspace of the collection base has been removed and the butane is filling the remaining headspace. Additionally,  if the pressure starts to increase after an incremental venting procedure that is a good indication that the nitrogen has been released from the system and the butane is building pressure within the system. If the tank PSI remains the same after a venting procedure then nitrogen is most likely still within the system. Recovery: Once the nitrogen has been successfully removed from the collection base proceed to vent the nitrogen from the empty recovery cylinder and pull the recovery cylinder and the associated lines under vacuum. With the nitrogen now removed from both the collection base and recovery cylinder you can now proceed with your recovery procedure  Disconnect the nitrogen gas line and the butane line from the closed-loop system. Properly store the nitrogen gas cylinder and the recovery tank according to safety guidelines. Using nitrogen to inject butane into a closed-loop extraction system requires a solid understanding of the equipment, processes, and safety procedures involved. Always refer to your closed-loop system's manufacturer guidelines and follow best practices for safe operation. How Much Nitrogen Pressure Do I Need For Adsorbent Filtration/ Color Remediation? 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.
