SPP source

[30xs]

I’ve been searching around to no avail looking for SPP. too many irons in the fire currently to be able to make my own. I was hoping to start a thread that may get some links to help me and some others looking for the same. I’m looking for SPP for a 3” column 36-42” packed section.

I've searched and do not recall finding anyone who makes SPP at the proper dimensions for a 3" column. SPP is typically made for 2" and smaller columns. I've always been interested in trying SPP, but it's so darn expensive. I considered making it too, but Lava Rock works so darn good that I've lost interest.

Maybe this is an option, certainly the price seems good?

I think that size is best for a 2" or smaller column.

Since my CCVM is 2" I got some from them, haven't had the chance to use it yet but it looks great.
The shipping is horribly expensive on the website, if you send them an email they'll quote non express shipping. 4 liters cost me 575 pln (about 140 USD) delivered, it did spend 2 months in transit from Poland to the US though.

http://stainlessstuff.net/parts.html#packing is another source for small SPP. Again shipping is the itch.

AliBaba is your friend for anything custom and it's where I got my SPP (though the specific seller I got it from doesn't appear to be in operation anymore or I'd link to them). There are a few suppliers who make packing and will do custom dimensions based on your requirements. Best to go with a request for quotations and let sellers bid against themselves to get the best price. SPP is never going to be cheap but it's likely the cheapest source.

I hate that you made me look because it looks like there's now sellers doing ProPak knock offs and it's going to be very hard to shake the idea that I don't need it at all...

I have some lava rock, just haven’t started processing it yet. What size are you running, 3/16”?

Just over 1/4". I was in an obsessive mood one day and measured 40 random pieces. The average size was 0.27", just over 1/4". Clearly some pieces are a bit smaller, but I wasn't going to agonize over the sizing of every individual piece. I just used a kitty litter scooper and it appeared to size it right enough.

I got mine from Kegland https://www.kegland.com.au/products/3-4 ... _ss=e&_v=1.

Definitely not cheap, and not sure how bad the shipping to the States would be, but they seem to work ok.

How much would it take to fill a 2" x 40" column? As in liters of volume.

2" Tri-Clamp has an ID of 1.88"

2" Tri-Clamp 40" long has a total volume of 0.48 gal (2.18 liters)

Thank you sir. So if they come in .5 lt bags... I'd need like 5 or 6 bags. At 39 dollar's a bag. I see now why everyone says it's so expensive. But I guess they would last year's. I think I will be getting me in the near future.

I use to SPP to reduce the column length needed. I think that's true for most SPP users. 1 liter gave me 20” in my 2" type M copper column the ID is bigger than a ss spool but I got more like 1 1/4 liter from my supplier. I can easily produce clean azeo at a pretty good clip with that. I'm sure you can run faster than me with 40" but I doubt it will be twice as fast, there's a point of diminishing returns somewhere.

You probably have read these threads but if not give them a look:

Thanks for the feedback. And the links to these threads.

My buddy champagneave in North America is still making it. I have 6 liters in my 3 inch boka and can pull azeotrope. I typically run 3.2 lph from a 10 percent wash. But can run way faster than that I was going from speed with as clean a possible slower was not any cleaner.

I also found wider cuts and better compression of heads like Odin and others mentioned in other SPP threads. For neutral I was typically in the 45-50 with doing strips then spirit run. I now don't strip now as no need but first couple tests tries with the SPP I did and got 65 percent keeps. I would say was cleaner than the runs with copper blocker.
