Quick n Free; we did it first link stripping FFAs with sodium silicate.

So what's the verdict on this stuff from a commercial producer standpoint? Is this product worth it?

I'd need to be able to push 250 gallons of oil with solids content <5 microns, in about 4 hours, so around 6 GPM.

If this product actually holds 12 gallons of water per lb. it seems like 50 pounds would need to be cleaned every 25-30K gallons? Assuming a 2% initial water content.

I'm just thinking outloud, but do you guys think that a flow-rate like that would be achievable with a thorough level of absorption?

What's the bottom line here guys?

I built a quick PVC tower to test some QnD in and discovered one issue anyone considering it should be aware of. I used a similar design as listed on the QnD tower design page . They specify using a 30 mesh screen for the filter bed and list the material size as 1000 micron.

"Quik 'n' Dri™ come in granular form 1000 microns in size".

Not having any 30 mesh screen I cut up a 100 micron bucket filter and used that. 30 mesh is 595 micron, 100 microns is almost 6 times smaller. But even this is not small enough.

After setting everything up I filled the column and using a gravity feed to slowly drain some BD off into a tall glass beaker. That is when I discovered a potential problem with the design. Seems the size of the granulars are not uniform and may contain a much smaller dust size particles.

The fuel was very clear, so clear I could make out small particles that looked like water droplets or air bubbles falling to the bottom of the beaker. After taking 4 samples I realized these were actually small clear particles of QnD falling to the bottom. When I previously bench tested this I used a coffee filter and did not notice any fall out. I let this beaker set for a few days to be sure, they stacked up on the bottom like little clear dust particles.

To work around this issue and finish drying a batch of fuel I installed one of those cheap inline 4 micron fuel filter after the column and retested. Nothing further was observed passing the filter. That worked well for about 50 gallons of BD, tonight that filter stopped up and it was clogged with fine gel looking particles. I also have a 10 micron oil filter coming out of the wash tank directly before it goes into the column. So I'm pretty positive this could cause some fuel system issues if left unchecked.

Has anyone else noticed this?

Glad to hear someone else noticed this. I'm planning on that same type setup with the storage tank.

I currently use those cotton wound water filters on the way out of the reactor before washing. That takes it down to 5m, so might just move that one over to the drying side before the storage tanks and let it catch the particles.

I just used my quick n dri for the first time and so far like it but here's what I noticed. I had the QnD in my druy barrel where I was drizzling fuel thru it from my drywash..
The next day I water washed and when I was done I sent that batch to the dry tank. My QnD is between 2 1 micron filters and then I have a long pair of panty hose full haning to the bottom. 1o hours later I realized I left my new QnD hanging in the top of the barrel and the panthose full and was pissed because I thought I was gonna have to dry it out already. Well with 45 gallons its safe to say that it did not dry it all but everything was still crystalized. I know what is is suppossed to change to because I had a small bucket with a small amount in the bottom that turned to goo..

Why do you think the part that was in the wet fuel didnt absorb after 10 hours.. thats concerning. Do you think the 1 micron filter blocked it?
