soil moist say their standard product cannot tolerate high salt environments.

They say a highly crosslinked polyacrylamide bisacrylamide copolymer is what is needed but they can't produce any at the moment due to long term production commitments.

I actually would prefer the crystal/gel to be mineral tolerant and actually even absorb them as well.

When first looking into these super absorbents I was really encouraged by this possibility since its just one more level of purification as far as I was concerned.

Additionally we have several sources of used cooking oil where being intolerent of salt could be a problem however if your not worried about introducing water anymore because QnD can remove it effectively then I'm not opposed to washing my oils impurities out... Just don't use Brine!

Did you try sprinkling salt heavily on a small bit of saturated QnD? What happened?

I have some of the stuff I got sprinkled with a lot of regular table salt and it seems like there is a lot more water transfer to the salt and the paper towel. In the course of about 5 mins or so it seems to have lost about a 1/4 of its size.

I also have a piece of it just on a paper towel at work in the air conditioning just seeing how long it will take before it is dry again.

After about 30 minutes or so.

Paul,

I think you'll find like I did. It sticks to the paper towel It's easy to removed, but the stuff likes to fly around when scraping it off the towel.

I put mine inside a 1 gallon ziplock bag and shook it and scraped it off in the bag.

It is really easy to get off (not like it was glued), but I didn't want to lose any of the QnD.

Nice results on the salt issue. That could be an easy way to do a *turbo* drying of the QnD when you need it again in a hurry!

PS- Paul, FYI- if you use the "Display Image" button in the toolbar when making a post, it will show the picture in the thread.

So far it has not gotten stuck to the paper towel. What I have noticed is after it starts to go opaque in color it seems that water loss has slowed a lot. Currently it is about 1/2 it's original size and the other "control" piece is about 1/4 down in size.

I found that a small paint brush worked great for moving Q&D around on the towel and herding it back into the container.

So we now know it is not a high salt resistant type so not a bis-acyrylamide with high levels of crosslinking. Sounds like the same results you would get with a garden soil gel. A medium crosslinked polyacrylamide with a pottasium polyacrylate copolymer.

How did it stand up physicaly to the salting? Kept its grain size? Didn't go to goo? Repeated wetting and drying cycles can apparantly fracture polyacrylamide crystals into smaller grains. Easy enough to cope with by the use of layered screens to observe when it happens and by how much but something you need to be aware of.

Just to be sure though was this QnD and has anyone with QnD replicated the result?

Ok well I came back to work and the piece that I did not "salt" was dried back down to its original size and yes according to john galt it's pretty stuck to the paper towel.

The piece that was "salted" has not changed in size it seems that the salt has made a layer on the outside that is restricting the water from evaporating.

So for drying I would use parchment paper from the bakery section or some other non-stick surface to dry this stuff out on.

1.How did it stand up physicaly to the salting?
At first the water came out of it fast. Then it turned opaque on the outside.

2.Kept its grain size?
It kept it's shape more or less.

3.Didn't go to goo?
Nope no goo.

Salt did not destory it I will wash the salt off and see if it dries competely.

My comments might have been misunderstood. I've found that Q&D grains from my fuel drying test column shed most of the biofuel onto the paper towel and DO NOT stick to the towel or other grains as they quickly dry in open air.

I have not tested the Q&D crystals with pure water or with salt as those are not substances I add to my fuel during processing, and thus the results of reaction with pure water or salt is not of interest to me.

Dear ANT
You do not know what QnD is whether it's a polymer cross-linked with bis-acyrylamide or simply Jello gelatin cross-linked with pea soup. Frankly, up to a few weeks ago you didn’t even know what an absorbent was and apparently even with your vast store of scientific knowledge you were still unclear about what a SALT was until last week when you had to be educated by a poster who had become tired of your trolling.

By coming to this board with QnD, we have move the knowledge frontier in five weeks more than you have in your five years of postings, and you have offended us so much that we are thinking of no longer providing previews of our products on this forum. What does that say about you and how much you are working for biodieselers?

ANT your interest is not the pursuit of knowledge it’s the pursuit of attention. You seem like a lonely person cooped up in you basement crying out for attention. Apparently you have spoken with some superabsorbent wizard in the UK and your knowledge far exceeds everyone else’s. Why don’t you take that knowledge create a thread that does not reference QnD (stand on your own two feet without using our product as a crutch for getting attention) and discuss those innovative UK absorbents?

Be the leader you think you are, move the subject matter forward on your own independent thread and quit being a TROLL.

Well in all respect I think that I have moved this thread off course on my posts and I will stop if there is further interest I will start another one with my experiements. The product that I have is not Quick'n'Dri but a soil additive for water retention.

Hi Folks
As promised we have made Quik ‘n’ Dri™ available via your favorite biodiesel supplies retailers. Please visit the link below to be taken to these retailers’ order pages.

That reminds me of the time when Alcoa threatened the Australian Government that they would just walk away from one of the largest and Richest Bauxite deposits in the World and not develop it if the Federal Government did not do what Alcoa wanted.
At the time I told anyone who cared to listen:,
"Sure, Alcoa is just going to walk away from one of the richest Bauxite deposits in the world unless they get their way.
Pull the other one"

I've been testing Quik 'n' Dri and find that it integrates with VO fuel processing quite well.
http://biodiesel.coorga.com/quik.html

The cold upflow processor produces clear dry VO. The upflow is run at temperatures below 10°C 50°F to separate the PHO, fats and the water associated with them. The clear dry oil is mixed with kerosene\D1+jetB then filtered, settled and filtered into the vehicle tank. The VO from the upflow settling can be HPT moisture tested to check for dryness. The solvents make filtering and mixing the fuel blend much easier in the cold temperatures. The only disadvantage is that HPTs are only valid before the solvents are added to the mix.

I wondered if the barrels of VO fuel mix might absorb moisture from the air, so I experimented with some Quik&Dry. It seemed like a good idea to add some Q&D to the processing as a trace moisture absorber and an indirect indicator of the moisture content in the fuel. I'm using an inverted 5gal water cooler bottle with a hole cut in the bottom to support a reusable 'canvas' shopping bag for an intermediate filter\funnel into the last settling barrel. The water cooler jug neck fits into the bung on the 30 gal poly barrel.

As it happens a UniversalWaterFilter fits snugly into the neck of the jug.
The cartridge is easily disassembled, and the bag containing the water treatment particles removed to provide space for about 75ml of Q&D with headroom for expansion with the cap replaced.



This Q&D column is good assurance of dry fuel and as an indicator of any moisture in the fuel mix.

I tested some bd and the resultant Quik n Dri is now somewhat gooey. Would this indicate fat in the bd? It looked clear to start with.
Joe

It's normal for Quick N Dri to go from crystal to gelatinous slimy goo as it absorbs water.

Please excuse me if I missed the answer further back, but what is the prefaired way to use the Quink N Dry ? ie I gather that a tower is ideal but up flow or down flow and at what rate.

Lets try to answer Rich DaTech's question: Does QuiknDri absorb methanol? Will someone who as some virgin QuiknDri (Graydon?) please place a weighed amount of it in virgin methanol and after a suitable period (6,12,or 24 hrs)drain it, blot it and reweigh it. This should answer the first question.
Then we can move on to the question of absorbing water from methanol.
Now prepare a solution of water in methanol. Lets start with 5% water in methanol prepared by adding 5 mls of water (distilled if available) in 95 mls of virgin methanol or better 5 mls of water in methanol to a total volume of 100 mls. Repeat the same experiment (run them both at the same time if you wish) with a carefully weighed amount of QuiknDri (5 or 10 g of Quik&Dri.
We can repeat similar experiments with dry biodiesel and even WVO which are contaminated with known amounts of water, water & methanol etc. and build up a reliable base of knowledge.
Sincerely,

been offline busy with life for awhile. I wont bother wasting time on Qnds personal comments. They speak volumes about the person behind them. Your arguments are the personal attacks of the playground bully, attacking the man instead of the ball as we say when people ignore logical fallacies to attack the speaker whilst avoiding rational discussion of the facts.I was surprised to find them as Rick assured me he and the other vendors had asked QnD to stop posting and ruining his own press.

Regarding what I know and don't know if you had any scientific understanding you would know that you can know what a thing isn't even if you don't know what it is. And this is established by testing and observing the results. You will note that a later posting confirmed that that the material being tested was indeed a garden type polyacrylamide as I suggested.

Plus I think you protest too much just because I do have a good idea of what you sell. No other reason for you to be such an nob. You had no problem when I asked exactly the same question about polyacrylate; you rushed to explain what a fair point it was and how your product was better. When I repeated the question with polyacrylamide instead you were silent on facts and hostile and personally insulting. Not hard to see the pattern is it?

You have advanced biodiesel? lol you knew almost nothing about your 'own'(repackaged) product when you came here and have depended on our member vendors to do the research for you. All you have done is brought polymers to our attention. You have contributed precious little fact apart from that.

Yes I do learn as I go but I am a quick study and more importantly I understand the nature of scientific proof and experiment and favour it over sales hype, vague promises and evasions. You could try reading Karl Popper on the logic of scientific discovery if you feel like catching up. Or some of the factual Asimov texts if you want an easier read.

As for what your threats to take your ball and go home mean about me; they mean I wont be bullied or threatened into silence by nobs but they say a lot more about you...
