Cannabis Hydrocarbon Extraction Systems

Hydrocarbon extraction begins by placing cannabis or hemp biomass into a sealed extraction column. A hydrocarbon solvent—usually butane, propane, or a mix—is then introduced under controlled pressure and temperature. As the solvent passes through the material, it dissolves cannabinoids, terpenes, and other desirable compounds, creating a cannabinoid-rich solution.

This solution is collected and routed into a separate vessel where temperature and vacuum are applied to remove the solvent. Solvent recovery units reclaim and condense the hydrocarbons for reuse, making the process both efficient and sustainable. The remaining extract can then be purged further or refined depending on the desired end product, such as live resin, diamonds, or sauce.

Throughout the process, modern hydrocarbon systems use jacketed vessels and precise temperature control to maintain product quality and reduce the risk of degradation. Compliance with industry safety standards, such as using ASME-certified components and proper ventilation, is essential to ensure safe operation in a licensed cannabis or hemp facility.

Hydrocarbon extraction is incredibly versatile. Processors can create a wide range of products including live resin, cured resin, diamonds and sauce, shatter, budder, and terp sugar, depending on post-processing techniques and starting material.

Most systems use butane, propane, or a blend of the two. Each solvent has its own characteristics—propane is more effective at extracting lighter terpenes, while butane is ideal for capturing a broader spectrum of compounds. Blended solvents are often used to balance yield and terpene preservation.

Yes, when performed using closed-loop systems built to industry standards. We offer hydrocarbon equipment that includes ASME-certified components and safety features such as jacketed vessels and recovery units. Proper ventilation, fire suppression, and operator training are also critical for safe operation.

Hydrocarbon extraction offers several key advantages that make it a preferred method for producing high-quality cannabis and hemp concentrates. One of the most significant benefits is terpene preservation. Hydrocarbon solvents like butane and propane operate at low temperatures and are highly effective at capturing volatile compounds such as terpenes, which contribute to the flavor, aroma, and overall user experience of the final product.

This method is also highly versatile, allowing processors to work with dried or fresh frozen material and to produce a wide range of concentrate types—including shatter, live resin, budder, wax, diamonds, and sauce. This flexibility supports both small-batch craft processors and high-throughput commercial labs.

Efficiency and throughput are additional strengths. Closed-loop hydrocarbon systems are capable of fast cycle times and high solvent recovery rates, making them well-suited for continuous operation. These systems are also relatively compact, which allows for optimized space utilization in extraction labs.

From a cost perspective, hydrocarbon extraction is often more economical to set up and operate compared to other solvent-based systems. The lower operating pressures and temperatures reduce energy consumption and can simplify compliance when properly engineered for safety.

Finally, product quality remains a leading reason why many processors choose hydrocarbon extraction. It consistently delivers high-potency, terpene-rich extracts that retain the full-spectrum characteristics of the plant—an essential feature for many consumers and brands in today’s market.

Throughput varies by system size. For example, the 5.HX is ideal for labs processing around 80 lb per 8-hour shift, while the 15.HX and 40.HX are better suited for mid- to high-volume operations, with capacities exceeding 200 lb per shift or 40 lb per run, respectively.

Most hydrocarbon extraction systems have cycle times around 30 minutes, depending on variables such as solvent blend, temperature, and material type. Efficient solvent recovery systems can help speed up turnaround between runs.

Installations must comply with local fire codes, ventilation requirements, and building standards. Root Sciences can assist with facility design and layout planning to ensure your lab is properly configured for hydrocarbon extraction operations.
