    Hey everyone, sorry for the newbie questions but I’m trying to learn. I have a Mk3 terpenator with a 450g dewaxing column and a 20lb n-butane tank and a 30# recovery tank. As I said, I’m a complete newbie, so my understanding of the process previously was that you would have the n-butane tank hooked up, it would run through the material, then you would recover it into the recovery tank. However, after reading and watching videos (particularly from the Terpp Extractors YouTube page), it seems like I should be doing that process (not exactly the same as the extraction process?) without any material first, which from my understanding is distilling the 99.5% n-butane into a more pure form, into the recovery tank? And then using that recovery tank to do an extraction, without the original n-butane tank hooked up?

    Again, sorry if these are stupid questions, I’m just trying to learn and bought this system because I wanted to do it the right way. I have a great setup to do it at my warehouse, I have proper ventilation with explosion proof exhaust fans, etc. I’m just kind of confused at this step of the process. I appreciate any help



    You do have to clean the butane prior to extraction. You can totally blow up your house if you don’t know what you’re doing. I had a veteran extractor blow up one of my houses once. You need to 100% understand the volatile/explosive gasses you are using and know exactly how many ppm/ppb it takes to allow for ignition. You need to understand how to safely handle butane. You have to understand static electricity and grounding. My friend spent 9 months at UC Davis burn center and he is a well-known extractor that writes books. I’m not telling you what to do, but I wouldn’t even be running butane because it snot an FDA approved solvent. I couldn’t buy your products because they are butane extracted. You should sell that rig and buy an ethanol rig. You can die if you don’t know what you’re doing.

    SierraGold I love that not only are you preaching safety but stating rules that need to be followed.


    Bob Rapp

    Please stay away from butane, propane, or any solvent that is vapor at room temperatures and pressures, such solvents are EXPLOSIVE and VERY DANGEROUS. Better to use solvents that are considered suitable for use in preparing pharmaceuticals or foodstuffs and to guarantee that residual solvents are adequately removed from final materials before they are used for human or animal use.

    What are you really trying to do?


    Bob Rapp

    While it is much safer to use solvents that are liquid at room temp/pressure, these solvents may still be flammable, even when they are considered food grade, please be careful!
