[SOLD] High Performance Random Packing - Saddle RIngs

Mtr_Distiller

1 CF would be plenty for a spool 8x20. I'm open to reasonable offers for 1 CF of the Saddle Rings above

Just in the interests of transparency @Mtr_Distiller , are you a supplier or just offloading some excess material that you have?

Mtr_Distiller

Not a supplier...Just a distiller trying to sell extra stuff

punkin

thanks for the clarification.

Mtr_Distiller

yw....no problem

@CothermanDistilling said: If someone has access to the Wiley stuff via their work or something, this looks like an awesome article.. on using packing with ethanol/water:

They use an 8" diameter 1.2 meter packed section and testing with 4 sizes, metal, plastic, and the IMTP version

Ask and you shall receive.

Scihub is a wonderful thing. It accesses all those paywalled studies we all need in our lives. I’ve always wondered why if government subsidies or funding supported the school or institution that did the study, shouldn’t it be available to all the taxpayers?

Thank you!

Conclusion

The results of this study on packing performance in ethanol-water rectification demonstrate very good efficiency of random packings. The best is the smallest dimension of Raschig SuperRing with a mean value of HETP = 0.28 m. It is 28 % better than the structured packing, HOLPACK, used currently in the ethanol production industry

I say we go in on a cubic meter of the smallest or next to smallest stuff..

grim

Given the performance was best with the smallest size (20mm) in a roughly 8" x 10' column, I say go with the smallest.

However, looking at Alibaba, there is even smaller yet - 15mm (Super Ring 0.3) - suspect it's going to be fairly pricy, as the packing density and weight starts to hit absurd levels.

grim

With that HETP, I'd go 16', 6" column - slightly over 17 theoretical plates - 0.1 cubic meters.

Mtr_Distiller

.28m HETP = 11". At that figure, why wouldn't you just stick to conventional bubble plates? 16' section could be 32 plates.

grim

Cost, since this is just a d*&cking around project.

I don't need the turndown and flexibility of plates in this application. It's going to be a continuous column, so it'll be running under a very consistent set of operating conditions.

Really only want to take 190 to 191.

I’d be kinda interested in some of the 0.3 rsrm. Would be for a 4” maybe 6” column continuous. Enough for 6-8 hetp worth.

CothermanDistilling

they make a .1 also: Raschig Super-Ring, Metal

I think:

  2"-4"   would be .1
  4"-8"   would be .3
  8"-12"  would be .5

I have a 17' section of 4" TC that would be fun to fill...

@CothermanDistilling - What's your thought on the column size necessary to support 30-40 liters per hour? This would be injecting 95%, collecting 95.5%, and extracting a tiny amount of bottoms product. I've got about 22' of height to work with.

I considered just using 4" x 4' spool - 4-5 sections - 16-20 feet of packed column.

Or, I could get a 20' stick of 6' 304 stainless pipe and work with that (surprisingly cheap).

I picked up a pretty slick tube in shell steam heat exchanger for the bottoms reboiler, it's got 4" triclamp fittings.

Ideally, process a drum of GNS in 6 hours - so start to finish, full batch within an 8 hour day.

grim

@Smaug - you guys have aspen? Run it baby, run it.

CothermanDistilling

the calculator flyingdutchman put on hd dotorg says with a RR of 5, you need 8-9" column to make 30-40L/hr

grim

Which link? Most of the ones I tried break as soon as you try to set the input/pot abv at 95%.

I haven't played with that worksheet for a while. Was trying to see if I could use it to help with designing a 4" stripper

Talking with Sulzer, the rep for the northeast lives in the same town as me.

I've read this before and was a great read. Unfortunately, FLYINGDUTCHMAN no longer appears to be active on this site nor any other that I've come across.

no reason you cannot use that knowledge as a stepping stone... we found a black hole without einstein being active on the forums.....

Sanitary tubing comes standard in 20’ lengths.

It’s surprisingly inexpensive compared to finished spool.

Do you take it to a local shop to have the ends/ferrules welded on?

Really does make one wonder what the outcome of a packed 20' section would be.

20 plates using most standard packing, closer to 40 plates using structured.

Fiji_Spirits

Is anyone going to move forward on this stuff?

grim

I'm getting some quotes from Sulzer for loose packing, and structured melpak to fit spool.

@Smaug - one of the sales engineers might give you a ring - just a heads up.

Fiji_Spirits

Are they offering the rsrm?
