Closed Loop Recovery

Hey guys,

I'm just starting making bho. I'm looking at purchasing a closed loop system and I'm wondering if after I have done a run and if I have lost some of the butane during the process can I just use the can tap tool to add another can to the recovery tank with the recovered butane in it or do I have to empty it first and pull it to a full vac before I add more butane.

I'm not really sure what the purpose of vaccing the recovery chamber is. What does it do?

I just want to have everything down before I start! Thanks.

You can add another can of butane, but be careful to not over fill the solvent tank. This is where a sight glass on the tank would come in handy, Or a scale to determine
how much butane is in the tank. Contact the extractor company before filling it and ask how much they recommend filling the tank. As for vac'ing the tank.. what that does is lower
the oxygen saturation. Helps to prevent the oxygen from feeding a flame within the system( not that this should ever happen). It also assists the butane to flow more freely into the tank when using a can tap or valve.

Sorry one more thing. Could you explain to me the reason for putting it in a vacuum chamber when purging?

My suggestion is if your planning on operating a closed loop system. Spend the time to research and how your system works, what your solvent will
do in a given situation. This is especially important to make safe bho. Don't rush into a system without knowing 100% what to do. Thats how
accidents happen.

Haha well that's what I'm trying to do! I have been researching threads and I haven't found any thread that specifically explains why you vac. Maybe I'm not searching the right terms.

I want to make clean bho and understand how everything works. It's kind of hard when I don't have a mentor/ am relying on finding all my information on threads or websites like Skunk Pharm, which has terrible web interface.

I appreciate the advice, but it doesn't really answer my question.

With a tamisium te175 you lose about 40 grams of butane due to this or that.
There is a max that any tank will hold safely. The tamisium tank max is 400 grams. If I do one run and lose 40 grams I refill with no more than 40 grams for a total of 400 grams. Max the tank holds.

Be sure if you're using cans in a closed loop that you're distilling your butane to get the lubricants out. Not sure if this is still holding true for every can mfg out there, but common practice to make sure it's as clean as you can get it. We distill about once a week with pretty good results and leaves me with feeling of knowing things are how they're supposed to be.

Deep cold is your friend when filling tank back up, and make sure you empty any atmosphere that might have gotten caught in your supply tank by freezing tank and opening your vent valve.

Solvent tanks shouldn't be filled 100% either in case of a temp flux, we typically stay at about 70% capacity, and even with a 30lb tank, it still allows us to even run 5lb columns.

Welcome to the game though, my biggest suggestion would be to read your fucking face off before posting more remedial questions though. Many in the community will give you the "we didn't help develop and read all this info over the last few years just to have newer folks come in and ask for quick answers"

http://skunkpharmresearch.com/ Best single source for information, IMO.

Thanks everyone for the responses. I will keep all this in mind.

I understand the frustration with people asking simple questions. After I did a bit more reading I found my answer, and it was a lot more simple than I thought it was going to be.

I'm not looking for quick answers just trying to make sure I'm understanding everything properly, so I can safely make clean bho.

Thanks again.

Which system did you buy BT?

As noted you can add more solvent any time, but need to keep the fill below 80% to allow for thermal expansion. We keep track using a refrigerant scale.

Removing the atmosphere improves safety by removing the oxygen, and the non condensible gases which increase operating pressures.

What problem are you having interfacing with Skunk Pharm Research?

Where are you located? Close enough to Portland to take classes on operating a CLS?

I'm looking at getting everything from Best Value Vacs. What do you guys think about them?

I already have a heating pad from them that I'm really happy with.

Specifically this set up: http://www.bestvaluevacs.com/extractorlpkit.html

The set up of Skunk Pharms website is just really unorganized. I feel like their articles should be split up into categories, instead every article is listed on the side bar. I've only been on their website from my phone. Maybe it's better on a computer idk.

Im located in central Michigan.

Greetings from the U.P., me and a few of my friends bought the best value vacs and they work great, no complaints at all. I would buy an extra container of oil for the pump tho cause it doesnt come with much and you never want it to run dry, like any engine. Well worth the money and ignore the bad reviews, on the metal chamber one anyways, i cant say anything on the pyrex chamber one. Safe Blasting!

Yeah, I asked Joe for drop down menus, but apparently we can't with the existing template and changing templates involves more or less starting over. The best I've been able to do is start articles with the same word, like "the", so it groups them.

No shortage of what other brothers and sisters think we "should" do to make our site easier for them, but sadly there is a shortage of my pro bono time available to do that for them, so we've not gotten to it.

We've discussed hiring a professional to do it for us, but alas there is also a shortage of contributions to cover the cost of upgrading the free site as well, but we will discuss it again this year, after taxes. Last year we were able to limit our out of pocket loses to $4000, but this year may turn our first profit of less than we lost last year.

There were about 1,769,000 viewers internationally in 2014, and almost a half a million so far in 2015, so we have also been approached to monetize and allow advertizing, but have declined and continued to pay extra to keep the site clean for viewers.

Was that a mistake? Would charging for a more organized service be a better thing?

I'm not sure if you've tried crowd funding for the site at all, but I would definitely donate some money to help you all out. Possibly set up a gofundme page.

We've touched on it, along with other solutions, but stand up to our asses in alligators, so it was between shots, usually while simultaneously reloading.

Since this is the time of year I spend quality time with our tax attorney, I will ask him for his thoughts on crowd funding. My own understanding is that people don't just give you money, it comes with regulation, records, additional owner interests, etc, and flies in the face of our KISS operating style.

Like where this one went...."donations" maybe...id love to see a more refined 'reference' or some kind of organized information section on top of the colorful threads

All in all, this is the best place iv found for this stuff on the interweb, keep the adds out if at all possible.

KISS, sometimes i see your closed loop systems and scratch my head at all the tubing, and whatever else is going on and think, holy shit this thing is crazy complicated. So its principles work on heating one container, while the other is in an ice bath, so the hot gas is forced into the chilled vessel that should have vacuum applied. It goes through some kind of intermidiate third vessel collection? Does the recycled butane ever start tasting hashy? Like a bunch of diffeerent strains all mixed up? You guys might want to look into r134a. It's non flammable, non toxic, and a great solvent for perfumes and fragrances. Leaves a less noticably offensive inherit taste. Freon is the biz.

So if the recovery tank that holds your solvent has butane in it already and there is no way to pull a vac on it again, you can still can tap more solvent into the tank if it isn't filled?
