Extraction Grade™ hydrocarbons are essential in numerous industries, such as energy, chemical manufacturing and cannabis processing. They provide safe, efficient and high-quality solvents for various extraction processes. At Meritus Gas Partners, we specialize in offering high-purity, certified hydrocarbons to meet the rigorous demands of these industries.
Hydrocarbon extraction utilizes methods such as solvent extraction and fractional distillation to isolate and purify chemical compounds. In solvent extraction, hydrocarbons dissolve the desired compounds from raw materials in a closed-loop process. Fractional distillation then separates these compounds by their different boiling points.
Extraction Grade™ hydrocarbons are specifically formulated to meet the needs of industries requiring the highest safety and performance levels. These products are tested for impurities and designed to perform consistently across different extraction applications.
Hydrocarbons, characterized by their molecular simplicity and stability, are primarily composed of hydrogen and carbon atoms. These compounds are highly effective solvents for extracting nonpolar substances without altering their chemical structures. Their key properties include:
Many hydrocarbons used in extraction processes are volatile, meaning they evaporate easily at room temperature, facilitating the solvent’s recovery and reuse.
Hydrocarbons are chemically inert under most conditions, which prevents unwanted reactions during the extraction process and ensures the purity of the extracted materials.
Their nonpolar nature makes them excellent at dissolving other nonpolar substances, which is crucial for applications such as essential oil extraction and herbal concentrates.
In the cannabis industry, Extraction Grade™ hydrocarbons have become a standard for processors seeking to create pure, high-quality extracts. Because of their low boiling points, they allow for the precise extraction of cannabinoids and terpenes without the need for extensive post-processing. Their ability to preserve the volatile aromatic compounds makes them the preferred choice for cannabis processors looking to deliver a full-spectrum product.
Meritus Gas Partners provides high-purity Extraction Grade™ hydrocarbons tailored for extraction purposes, including:
To maintain the highest level of product quality and safety, Extraction Grade™ hydrocarbons undergo rigorous testing and certification. These tests screen for contaminants like:
These certifications reduce the risk of impurities and protect against issues such as fast crash (medusa stones) and contamination.
We follow strict process controls and quality standards to verify the cylinder’s purity throughout the process. Each cylinder goes through our proprietary cleaning process to eliminate residues left over from manufacturing, including:
Third-party tests have proven that our cleaning process effectively reduces residual particulates and oil from cylinders. While passive distillation can remove some solids, the process cannot remove contaminants with a similar chemical composition, such as benzene or hexane.
Refilling the tanks includes the following steps to ensure quality and prevent top filling:
The residual gas product and potential contaminants are removed from the tank.
The inside of the tank is inspected and washed if it is required for cleanliness standards.
Air and moisture are removed from the inside for a safe gas fill.
The tank is filled to maximum capacity, as determined by the Department of Transportation (DOT), allowing space for fuel expansion and spillage prevention.
The tanks are inspected and certified with a Certificate of Conformance (COC), ensuring their compliance with regulatory standards for safety and technical standards. We complete analysis and traceability in our on-site laboratory using a flame ionization detector. This detector certifies the product at parts per million.
Our specialty cylinder packaging includes the first DOT-approved LP 239 stainless steel cylinder that is corrosion resistant to eliminate rust and particulate. The cylinder options include:
We implement specialty valving procedures to reduce contamination during the process. Valving is an abrasive process, so de-valving and re-valving multiple times should be avoided. When cylinders are de-valved and re-valved, the integrity of the valve threads is compromised, and metal and debris are introduced to the cylinder. These are common metals and contaminants introduced during the industrial valving process:
We use solvents developed specifically for extraction, with high purities of 99.5%+. The extraction solvents include:
We developed the first standards for extraction, ensuring high purity in solvent products. The sum of all impurities is less than 0.5%, and water is less than 5 parts per million.
Top filling a cylinder refers to refilling a cylinder that has not been evacuated — emptied of the residual gas and unknown contaminants at the bottom of the container — and put under vacuum to remove moisture and air. As a result, cylinders that are top-filled have gas product filled on top of the residual product. While top filling is common in industrial gas filling operations, this technique creates uneven mix ratios, introduces unknown contaminants into the gas, and makes inconsistent purities.
Black flakes and particulates get into the cylinder because they are left over from the manufacturing process of the cylinder. Carbon steel cylinders rust over time — if moisture is present, the rusting accelerates. Solvents will dissolve rust and any nonvolatile residues from the cylinder wall. We recommend internal washing, in-line micron filters and stainless steel cylinders to eliminate particulate and residual oils.
Purity is important in gas cylinders because purity is related to consistency — the higher the purity of the product, the more consistent it is. To meet higher purities like 99.5%, impurities and contaminants need to be removed. Since lower-purity products have various purities, they can have higher amounts of harmful contaminants like acetone, hexane, alcohols, C6+ and BTEX.
Hydrocarbons from Meritus Gas Partners are pre-distilled and ready for use. Distillation is a passive distillation process similar to filtration. While passive distillation removes some solids and particulates, contaminants with a similar chemical composition cannot be eliminated. Choosing our distilled products ensures purity and prevents downtime.
