Why Care about Extraction Solvents?

Don’t know where to begin? It’s easy. With over 75 completed extraction facilities designed, permitted, and in operation, we have the experience to help you make the right decisions. Contact Us to learn more.

Here’s just one example:

The vacuum (air pressure) in your extraction system dramatically alters the boiling point of certain solvents, and small changes or inconsistencies can make differences that almost seem to defy common sense. Did you know there are solvents that, under certain conditions, can boil at a mere 15 degrees F, or well below the freezing point of water? It’s true, look up the boiling point of ethanol under vacuum.

We’re hearing about a disturbing trend in the industry where processors are altering solvents and mixtures to address concerns such as taxes, extraction process efficiency, and solvent recovery. As the industry grows, the internet has become rife with inexpert advice and supposition. It’s just plain dangerous.

Experimenting on your own can have real consequences including fire code violations, personal injury, and property damage. Any time the solvent mixture is changed, the system requires a complete re-permitting effort (see 2018 International Fire Code Ch 38).

Fortunately, you can easily avoid these pitfalls when you hire a professional engineering firm to design a safe, efficient, and cost-effective set up. You’ll save money in the long run by making the right choice the first time. As we like to say, “Great Design Saves Time.”

Here’s a summary of some common extraction solvents and some considerations with each.
