How about 2.5 pounds per column?

The Mk V manual prototype came on line yesterday and the new owner is having just too too much fun with it.

We ran 5 lbs of supposedly spent material, supplied by another supplier, using a Brand X extractor, and actually yielded quite a bit. We always throw way the first equipment cleaning run, so not sure what we can do with it.

let us know if it's faster!

I'm working on setting up a shoot out in Seattle, between the Appion, Caresaver, TR-21 and Haskel pneumatics.

so if any of you are doing more than a couple tubes a day, I highly recommend upgrading to a 2.5lb system. omg, so much of a time saver!

Mr Durden, did you build a MkI-style extractor, or just scale up the MkIII design to hold a larger column/collection vessel? I am running 6-8 columns a day, 5 days a week with my MkIII and I am seriously wanting something bigger. The MkV looks like the ticket, but until more 12x12's are in stock, I'm kinda SOL in that department.

 

[mr. durden]

a Ia using a 10x12 spool.

yeah, i'm not sure what i was thinking trying to run so many tubes on the IIIa. building the Ia was the best thing i've done in awhile. now we are going to need another 1.9 as we maxed out both our ovens with just a 2 tube run. granted it yielded about 18-20% :/

i wouldn't even bother with the V unless you are running 2 or 3 1.9's. i mean if you run two runs with the V, you'll need 3 ovens easily.

we are building a second Ia and picking up another 1.9 so that we can run 4 tubes a day no problem

LOL omg one 2.5lb not enough?!?! O_O I'm guessing with the 2.5lb you are not doing column flood/drains but just single pass?

Btw I received the emerson take-apart filter. God this thing is a BEAST. I love it. Thanks for the tip.

it really isn't given the volume of material we get. but you upgrade in one area and all of a sudden you are deficient in another. 2 columns max out our ovens :/

not sure what size filter you got, but here is something to note... sweat in/silver braze brass pipe that is threaded on one end and then use stainless fittings.... coupler, hex reducer, to brass 1/4" hose nipples.


GW, I'm not sure why this didn't stick out to me sooner, but the mt-69 is copper and butane doesn't exactly react well to it? i'm switching over to 25' of SS tubing/wort chiller to get away from using copper at all. thoughts?

@nakadashi... a modified bottom up single blast. basically i clock how long it takes to fill the column. usually about 1:30, then run an additional 3-4 times that amount, or about 6 minutes. then i close the dip tube valve and dump the main valve. usually takes about 2 hours to hit a point where we can dump the bottom spool inot about 3.5 9.5" pie plates sitting in individual pots of hot water.

my fume/exhaust fan for moving this part of the operation inside was a fail as the outfit put on a normal motor rather than one that is explosion proof. 10 days out on a new one :/

General observation... if you aren't running dry ice, you really should. we chill our 50lb tank for about 2 hours if we don't pack it in dry ice the night before. there is a NOTICEABLE difference in color of the oil running the same ground up material from a tank that was frozen in a freezer and then packed with dry ice versus the same frozen tank that was packed in dry ice for about 2 hours. not only do you help dewax your oil to some degree, but lighter oil equals more money for the most part.

we have an account at airgas for dry ice, who also carry the pellet form we like, and we basically get it for half the price you'd get at the grocery store.

amazing job GW! how many ovens are those guys running???

I really want to run dry ice but i don't think it is safe to do, as a lot of the components in the MKIII are not rated to that low of temperatures(-78.5F) All of the viton gaskets are only rated to -20F the BUNa-N can handle -30F. and i have heard stories of welds cracking under the temperature stress. Regular ice and frezzer packs at(-10f) work great for me, a tiny amount of color improvement and less wax pickup isn't worth ignoring component temp ratings when we have gone to such great lengths to make this process relatively safe.

 

[mr. durden]

@regis... you just have to expect to replace things more often. it is actually safer in the sense that if you get a leak, the butane will dribble like water versus being gaseous. you do have to keep checking that everything is tight, but usually just in the beginning. sure the gaskets will probably degrade quicker, but it won't be a sudden failure. plus, you should be rotating them anyway.

although dry ice is super cold, by the time it is circulating into the system, it is warmer than that.

the big filter dryer that the butane hits first might be -40, but i'm boiling off the butane in the 10x12 spool and it is currently 0 degrees.

welds cracking would be a sign of a bad welder

there are trade-offs, but i think dry ice is much safer in some ways.

 

[kronus]

can't wait to buy my first closed loop system =)

 

[JColtrane]

Gotta agree with durban on this one ... been using D/I for years without any problems. However we've started to get even more cryo, with alky d/i boils ... now that's cold

Just outta curiosity, what kind of yields did you get out of spent material? I have just been tossing mine into the compost but if there is still value left in it I should be saving it for when I build an MkV

One large one, but I predict they may add more.

Typically we don't get much out of our own spent material (1 to 2%), but we scored this spent material from another processor, running a Brand X recirculating system, and it is probably not a good measurement.

 

[kronus]

hello does anyone know if its ok instead of blasting into glass pyrex to use like a stainless steel bain marie or stainless steel mixing bowl and most importantly if its safe to put the stainless steel container after the butane evaporates into a vac it pro to start the muffining process??

Thanks

may? more like will need!

 

[Kcar]

Can someone explain to me why it takes longer to recover isobutane or propane compared to N-butane?

Also, a friend of mine tried 'Cloud Fuel' in a lighter, and it didn't work at all. lol

Also, is the CPS MT-69 meant to be run in an ice bath?

Yes CPS MT-69 in an ice bath.

 

[mr. durden]

although i'm surprised GW hasn't chimed in on the safety of using the cps since it is copper. i'm switching to SS tubing modified kinda like a wort chiller and then using the same fittings that the dip tube is tightened with to get me to 1/4" hose fittings

We used a tall stainless bain marie when using an open column and it works well, as long as you aren't having to scrape it.

Because of their substantially lower boiling points.

Yes, the Mt-69 goes in an ice bath.
