since he isnt responding to questions pertaining to his product or points about the safety issues, its my opinion that his presence on the forum is purely for advertisement purposes.
 
Yep, I think it's all for advertising purposes as well. I also don't think he understands English very well, if he read, and understood what people were saying I have to believe he would have responded a little differently, at least defended his thing.
 
I fear that this device will cause problems and unless our Russian friend comes back and gives us some details of how exactly it works and how well it stands the test of time which can be dissected and discussed by the experts here on the forum that the whole thread be deleted. Remember the forum is viewed and rightly so as the place to come to learn about refining and recovery of precious metals and any new member reading this may not use English as his or hers first language may view it's appearance on the forum as a sign of approval without understanding our serious doubts of it's ability to perform safely.

I am sure it is not ment that way. The forum is a giant family and we all work close together to share information. Everyone just wants to make sure your equipment is safe and will do the job it is intended to do.
 
I am PhD of Chemical Engineering with many years experience. How Palladium found out, I am Serge Davydov (the male sex). I live in an apartment house and work in the bedroom (although I am not sleeping there). To refine of Gold Scrap, I had to design the setup for full neutralization of fumes and gases. Given my background, I made it quickly and with virtually no errors. Now I'm doing Portable Refining Systems (see my eBay - Portable Refining System) that have a commercial success.

I have one quick question to all:

How much metal (very approx) could be dissolved in acid at the same time, in order to work without a system of neutralization of acidic gases and vapors was impossible?

I want to design industrial system neutralizing and I need basic data
that i can't receive in my bedroom.
Best,
Serge
 
Hi Everyone!

I’m going to go out on a limb and do something that may cost me some credibility here if I have any. Having said that, here goes!!

The individual selling this device seems to not have a good mastery of the terminology we use. He seems to interchange the terms “refine” and “recover”

This is quite simply a scrubber using technology similar to that shown at:
http://goldrefiningforum.com/phpBB3/viewtopic.php?f=40&t=9115

and elsewhere here on the forum.

I have purchased one of the single reactor versions of this device. It is a modification of plans for a similar device used and plans sold by Charles Butler of Butler Labs in Bodfish, CA.

http://www.butlerlab.com/

Mr. Butler claims to have received EPA approval for operation of his lab based in part on the use of his similar device. Both devices, Mr. Butler’s and Dendrite’s operate on the same principal and use the same “activator”. The device in question works on the same principal as a tower/container of bio balls/marbles, having the gases bubbled thru it.

This device is effective in any process (refining or recovery) that creates gases lighter than air (not for use on HCL-CL as it produces Chlorine gas which is 2.5 times heavier than air).I have used my Butler unit for nitric, AP straight Muratic and AR processes. It is very effective at capturing and cleaning any NOx produced as well as off gassing of HCL and most if not all other gases we commonly encounter in common recovery processes found on this forum. I can’t testify to the gasses produced by refining, as the variety is too large and diverse.

I have only had this device for a month or so thus I can’t address the failure issue. I have been using the Butler design for over 5 years and it has proven to be very effective at capturing and neutralizing the various gases given off, that are lighter than air. My Butler device uses a 12 Gal. wet/dry Shop Vac. and I have had to change out the scrubbing/neutralizing solution 3 time in that 5 years. Of course the frequency of change out is dictated by usage. The solution must be pH tested periodically to ensure that the pH remains below 7. The lower the pH the more effective the scrubbing action.

As to being unsafe, any system has an unsafe quality, regardless of how technically advanced or well manufactured. The degree of risk is directly associated to the manner in which it is used. Any device can be risky if used foolishly. You can us a ink pen in a foolish manner and someone might end up dead (if applied with force to the juggler vain). I don’t see anything here that is inherently unsafe.

The type of scrap that can be processed is limited only by the process used and the size of the reaction vessel, as in any recovery operation.

When properly set up and used no corrosive liquids should come into contact with any parts other than glass or ceramics. No corrosive fumes should come into contact with the vacuum, as they should have all been neutralized by the scrubbing action and the “activator” chemical.

As to technical proof, this device employs accepted, proven technology. It is just presented in a smaller than usual form. There appears to be nothing inherently unsafe about this device. Safe use is reliant upon the user.

Both links you've provide offer nothing to back this unit(s) in question. We know the principles behind scrubbers and how they are constructed. What we are looking for are hard facts on these units. Specifically pertaining to the safety of this unit. The inventor after all does claim it can be used indoors with all of our common processes (not too happy about this claim).

We want trials, compatible materials, strengths, weaknesses. Something. Anything! Not just it works because I said so. Even if he just said it’s something you can use outdoors I would be ok with it. But the claim that it can be used indoors is a big one. That's my main beef.

hello gary,

i would be VERY careful using this thing, it looks more like a dinner server then a recovery process.....that said it only takes one mistake to kill yourself and possibly others around you, but that is where greed gets you. i have no background working with recovering any kind of PMs but i would still never in my life buy something that looks like this. maybe for giggles but other then that i would stay clear

that is what this forum and hoakes book is used for, i would rather use the stuff i learned here then some odd non patented crap i found on ebay. that being said why is it not patented....oh that right, because its a epic failure

sorry if i crossed a line here but i had to say my piece
 
like i said before, ive had too many runaway reactions to know that nothing is fool proof, with me being the fool. for someone in good health, its hard to imagine the difficulties in doing every day things when you have respiratory problems.i ruined my own health by doing something i had little knowledge of and have no one to blame but me because i pursued the issue with no prodding from anyone. i take great offense to someone claiming that a dangerous process using toxic, noxious and very deadly and life altering chemicals can safely be used in your home with family, friends and pets present with no other safety equipment used other than that being provided by the person making the claim.

electricity fails, circuits fry, glass breaks and accidents happen. this gentleman recommends that you use his product in an enclosed space without the safety nets of, PPE's , a fume hood,neutralizing agents in case of a spill, good ventilation and all this in your living space.

you sir, are more than a fraud. you are a very dangerous person, preying on other peoples greed for your own profit.

you've contrived a pretty tinker toy that will undoubtedly wind up injuring someone at the least and killing someone at the most.would you feel remorse? would you feel guilt? or would you file for bankruptcy to protect your ill gotten gains and concentrate on your next harmful gadget.

This looks nothing more than an over amplified mobile meth lab. The kind you hear about crimestoppers on tv saying if you see someone walking around with a backpack and a 2 liter etc, call it in.
 
You know for some reason i still kind of still like this guy if he would just answer the questions. I did a COMPLETE background check on Serge and other than the fact that he seems to be misguided somewhat he seems like a nice fellow. Serge i can answer your questions about the ratio's for the neutralization and how much gas it can scrub before it's done and all that good stuff. It took me many of hours to find the answers being as how i'm just a good old country boy and not a PhD as you claim. Those answers should come easy to you. Would i give you those answers? Yep!, if i thought you were even being half way honest with me i would. You said you were having great commercial success with your products. Why don't you take some of that profit and reinvest it into your product design and then we can talk about all the help you need. But with what you have now and where this seems to be going i wouldn't touch it with a 10 ft pole. Whither you believe us or not Serge it won't take but one person getting hurt with this and your whole plan for prosperity will be gone for ever. After all this is America and if anything you yourself should know how the legal system is here about lawyers suing people.

On a side note i was very interested with what you were doing with the copper sinks. I designed a product (coating) somewhat like yours but for a different application in the commercial home market here awhile back. Your product still has potential you just need to think different application substrates. Don't give up Serge but do change some things please.

On another side note here was my first generation scrubber design for my use. We are now at the 3rd prototype of this design and i call tell you EVERY fault it this design.

Where are you going to find the giant dustbuster and crockpots to go industrial sized?

Now that is a cool design 8) It looks like it goes from left to right with the connection to the reaction vessel being on the left and the exiting vapors to the right. Is this for smaller reactions like in flasks? Are you patenting it? I would like to see if I could come up with a similar design on a slightly larger scale. Just figured I'd ask :D
