Notice right away that you cannot use closed-loop extraction if you are not legally certified to do so. The reason is its capacity for potential misuse, which is why you can use closed-loop extraction only for legal purposes. It can be used for extracting oil, perfumes, and additives.

The Basics of Closed-loop Extraction

Closed-loop extraction is based on hydrocarbon extraction. It is among the most used extraction methods in the perfumes and additive industry. It can be used for extracting many hydrocarbons. What makes it unique from other extraction mechanisms is that it is always performed in a closed system. In a closed system, nothing from the outside can contact or get absorbed in the solvent. That’s why closed-loop extraction methods are much more efficient, reliable, and safe as compared to other extraction methods. 

How Does It Work?

First of all, the solvents are put in a tank, from which they are removed and moved to another area for washing over the solvents’ material. It is a cycled process, which means that the solvent has to repeatedly go through the same process over and over again. 

As a consequence of the washing, the hydrocarbon ingredients of the solvent, such as terpenes, get dissolved. The concentrate containing hydrocarbon ingredients is then refined, expunged from the solvent, and collected. 

Commonly Used Solvents

The most commonly used solvents in closed-loop extraction are:

  • Butane
  • Propane
  • Ethanol
  • Carbon dioxide 

Among the solvent, the most used and recommended is carbon dioxide. 

Why Prefer Closed-Loop Extraction? 

While there are many extraction methods popular in the industry, closed-loop extraction is by far the best among all. What makes it the best is its incredible safety. 

Safety should always be a part of the equation when it comes to making sure a system works efficiently. Closed-loop extraction is not only safe, but it also works way faster than any other extraction mechanism. On top of that, the results it gives are far better than any other extraction technique can provide. 

This system is safer because the hydrocarbon solvents used in extraction are extremely flammable. Keeping them in a closed system saves them from leaking out. Just make sure that you purchase a high-quality closed loop extractor from professional companies like LeDAB. 

Conclusion

For whatever purposes you want to use, just make sure you are legally certified to do so, and you use them for legal purposes. Always purchase and use high-quality closed-loop extractors because they are safe and cost-effective.
