Terpenation at Terpene Station

A friend of mine has many pounds of bubble he can't get rid of.
Is it possible to run bubble in a closed loop extractor?
Would the solvent flow or would it be stopped up by a gooey impenetrable
mass of bubble?

I just ran 200g of kief in the default column today, no problems. I would imagine bubble, being less concentrated than kief, should be ok too. However I should mention that the initial flood took 2 minutes. I opted to run it in a 'shower' style rather than the usual flood/drains cycles. Also during the initial flood the system reached -20"hg vacuum before the butane reached the vent tube. Therefore next time I do this, I will probably leave the appion off until the 'tane reaches the bottom of the vent tube to avoid dry running the pump.

With the bubble if you are afraid of an impenetrable mass, don't pack it too tightly. I packed 200g of kief so that there was plenty of space on both ends of the column, which may explain the long flood time. After running 'tane through it for a few minutes though it dissolved.

ah I did not know anybody preferred wax for aesthetic purposes. When judging purdiness a clear shatter is the obvious choice for me but I guess reasonable minds can differ.

Like purdy women and purdy cars, all have things to admire.

I need help with the proper gasket to order. I have the Brewers Warehouse sightglass and I ordered Viton gaskets from Glacier. The gaskets do not fit. I've tried the 1.5" sightglass gasket and the 2" gasket. Neither will fit my sightglass. Can someone send me a link to the correct viton gasket, please. I took a photo but am having trouble posting.

For sure.



Every time i run kief its darker.

Is anybody using anything to heat the column during recovery?

I had ours made at Paramount Supply and they did a nice job for not much money.

We use pipe heat wrap for heat on the Mk I and II columns, and silicone rubber heat mats on the Mk IV and V. The Mk III is the only one without heat and it would speed it up.

Heat on the column is probably the second biggest improvement possible for speeding up the recovery,

 

[icdog]

Thanks I'll try the pipe heat wrap. It is only used after the column dump?
I'm somewhat confused on why this matters. Once the dump is done isn't most of the butane in the collection pot?
Whats the biggest improvement for speeding up recovery?

There is a list on the SPR Mk III page with a link to the Brewers warehouse sightglass and a link to the gasket at Glaciier. This gasket doesn't fit the sightglass from Brewers Warehouse. I've read in this thread, and on the SPR site, many people using the same set-up. What gives?

If I have to have buy a custom made gasket for the BW sightglass, then what are the dimensiòns of this gasket?

Why is the ID of the BW 1.5" gasket larger than the Glacier 1.5" sightglass gasket?

Propane for Extraction

Propane for Extraction

Is anyone running 100% propane for extraction in a MK III? I know that the butane I am using contains some propane and that it has different pressure and temperature characteristics.

I was wondering about being able to purge the ethyl mercaptan out of the final product. My BHO normally has ~25 PPM residual butane and I know that ethyl mercaptan is detectable at 1 part ethyl mercaptan per 2.8 parts per billion in air.

So I guess the question is sort of two fold, how does 100% propane work and can you get the ethyl mercaptan level below detectable levels.

 

[RegisPhilburn1]

Im pretty sure you can buy pure propane without mercaptans just like you can buy pure butane from the specialty gas suppliers.

There was a guy in class this past weekend who was talking about running various mix's, including 100% propane. He was using a BHOgart system, however I don't think that should matter.

If you really wanted too, you might think about devoting a column to the Zeolite, and distill the propane, and recover per GW's reccomendation of Butane Distillation: http://skunkpharmresearch.com/vacuum-distilling-butane/

Now these instructions are for Butane, however I don't see why it wouldn't work for Propane as well ....

The butane does not flow freely down through the tube packed with plant material so it remains trapped in there waiting to be recovered. The biggest improvement speeding up recovery is heating your recovery pot.

The last list with the sight glass, was provided by one or our readers, as a service to the rest of ya'll. I've never listed a sight glass.

All of the sight glasses from Glacier Tank aren't the same either and one gasket doesn't fit all. I also don't like the quality of the gaskets from Glacier, so I had my own made by Paramount. It looked like some one carved the ones from Glacier with a pocket knife, rather than a die.

What I did, was take out one of the silicone rubber gaskets, and hand it to Paramount with instructions to make a dozen out of Viton.

No ethyl mercaptans in Instrument grade Propane and it does a nice job of extracting, though it takes about twice as long to recover. It cost about $100/Lp-5 less than n-Butane.

Once you dump, the plant material is still soaked with butane, and recovering it under vacuum, creates enough refrigeration to drop it below its boiling point, thus stopping the process. Heating it counteracts the refrigeration and keeps the process going.

Thanks GW. I might get some 6 inch spools made by a company. They have asked about the polish of the ss tubing and the welds. How much does this matter for the operation?

I have a BrewersHardware sight glass and ordered the 1.5 from them and gaskets from Glacier, but the boro glass part's O.D. is larger than the tri-clamp flange. Put the 1.5 gaskets that look like they were cut with a pair of kids safety scissors in and the fit was not perfect but i pressure tested my MKIII to 105psi and put in a horse trough and saw nothing. Then pulled a vac under water and it sat for several hours. Not ideal but have done ten runs and will be putting the 2" gaskets in today or tomorrow because it is the right thing to do. Paramount may still have GW's blank but sounds like they could solve our problem for a nominal fee.

Just read the first page, made my mouth water

It is important for keeping the surfaces clean.
