The type of plastic will be determined by the scrubber solution and type of gas you chose to scrub. In each column fill it up about 6in with the plastics. You will need to attach a line filter to the end of each tube inside the column. This will prevent you from sucking the media out.
Typically sodium hydroxide is used in a fume scrubber for aqua regia work. By maintaining the pH at 9.5 to 10 the nitrosyl chloride (the yellow gas component of a …
Also, from the figures I've always worked with, the nitric fumes must spend at least 9 sec in the caustic scrubber to get scrubbed - that's considering a packed column with a spray system at the top. Therefore, at an exhaust rate of 300 cfm, the scrubber volume would have to be at least 300 x 9/60 = 45 cu.ft (340 gallons).
In addition to the neutralization treatment, we realize the plant for the fume pre-treatment, which is particularly effective in the presence fumes containing Nox, emitted by nitric-based processes (such as the inquartation of gold alloys, production of AgNO 3 silver nitrate or similar processes).. The fumes abatement towers can be equipped with process …
First - there are two types of scrubbers --- (1) closed reaction scrubber - this scrubber works by drawing the fumes from the reaction vessel through the scrubber using a vacuum pump. Here is a thread (about building a fume hood) that also discusses …
All, The ICP result for my alloy metal is ready, Cu is 58%, Zn at 38%, and gold is not ready yet. This was from few pieces pf gold finger cards. I tried the following scheme trying to burn the toxic fumes coming out of smelting boards, to inert it through water then through a bucket filled with hot charcoal. Please advise. Regards Kj
The throat of the wye has to be a full 8" so an 8" wye and a 8 by 6 reducer on one leg and a 8 by 4 reducer on the other leg will work. The 6 inch drop goes into the top of the hood and the 4" drop runs to the top of the scrubber. In the 6" line, just above the hood where you can reach it, add a blast gate damper.

i did recycling as a home refiner a ton plus mobile boards and thousands of kg motherboards. alot of losses in start, many setups for fumes. first time think for medium type refining. setting up fumes scrubbers, furnance setups, and yes safety safety safety safety! thats really matter as i change my plans of using lead because i can not handle ...
Charged with treated activated charcoal (available separately). This fumes scrubber will scrub aqua regia fumes from up to 2 liters of aqua regia per run. A charge of treated activated charcoal typically will last for 5-7 refinings. If refining 5 liter aqua regia baths, two scrubbers, hooked in parallel, should be employed.
Has anyone considered pre-fabricating for sale a fume scrubber system for the small refiner that could be re-assembled by a non-plumbing / non-HVAC / non-electrician person? Sadly, I can put oil in my vehicle and do a bang up job as a computer triage technician but I suck at most handyman type things. I can read instructions and put …

Gold Refining Basics. Safety . Fume Hood. Thread starter Jmk88; Start date Feb 9 ... I doubt a "dry" scrubber will do the job. The fumes are wet vapors and need to condense back to a liquid to remove the NOX. Reply. notehunter494 Active member. Joined Dec 26, 2020 Messages 35. Oct 22, 2021 #3
I am designing a simple fume hood and scrubber that should eliminate all fumes. I will post pictures when I finish it. It will be a two stage scrubber that will allow the fumes to pass through very slowly. I am using aquarium bio balls to increase the the surface area that the fumes pass over. I started this project with a few goals in mind. 1.

a. You will have to either have to create a pump pushing the TOXIC FUMES into the scrubber or through the water. The first will probably force the toxic fumes to leak out and the second will cause your plastic drums to collapse (trying to suck the fumes through the drums collapsed mine). b. You will make the thing not as simple to operate.
Generally lab hoods are designed to evacuate 100 CFM for every square foot of hood opening. This gives decent airflow to remove the dangerous fumes from the work area. Fume scrubbing is a different matter. Build a hood with an appropriately sized blower and add a scrubber to remove emissions in need of scrubbing, like NOx, or the Sulfur …
This required a scrubber, but it was much smaller - about 5' x 15'. The blower was 250 cfm. (3) No air dilution. Most all self-contained, do-it-in-your-livingroom, karat gold machines on the market use this approach. Everything is sealed up, as much as possible. The only thing going through the scrubber is pure fumes.
giahylxag, I believe the fumes you're talking about are called fugitive fumes. They're the fumes that you can't really control when refining. The main refining fumes come from the reaction of the acids on the metals. Lots and lots of acidic fumes. These are best treated in a "closed" system. When I say closed, I don't mean sealed.
The furnance has it own saperate outlet. But fumes from crucibles are to be scrub. Fumes from the crucbles are corrosive . Looking to push fumes inside scrubbing liqued and the pass from a paked tower. Looking to use one already shown pum for mixing gases from furnance and a saperate pump in pcked tower.

This system is suitable for refining jewelry, bullion, coins, jeweler's bench sweeps and other similar material. Our aqua regia system, the Shor Aqua Regia Gold & Platinum Refining System, uses no nitric acid, is completely self-contained and employs an integrated scrubber to clean and neutralize all fumes before they are exhausted.
The rotating device is useful in the aqua regia refining process in presence of silver higher than 10%, reducing the chance of un-dissolved material and increasing the efficiency of the process. MAIN FEATURES: For the refining of alloy having a content of Au minimum 65% and maximum 15%. Minimum purity: 999,5/1.000. Input material: metal granules.
It is used when you have a blower that is not corrosion resistant and you blow clean air up a pipe causing the air in the hood to follow it. The reason you use a venturi powered scrubber is to scrub a small quantity of fume being sucked from an enclosed reaction. A flow of 10 CFM is good for that type application.
The EFZERO gold refining plants, produced by Italimpianti Orafi, can refine all kind of gold alloys without development of any sort of acid fumes and with recovery of nitric …
NO - if you are trying to "scrub" your fumes this is not the way to do it --- al you are doing here is making a "weak" acid which reacts with the metal which in turn produces fumes NaOH (sodium hydroxide) is used to scrub acidic fumes - do not use NaOH in your beaker for making a scrubber it will "etch" the glass - here is a link to a …
