My father was an operating engineer at Alford Refrigerated Warehouse. I was swiping lung darts of our his truck and ran across a sulfur stick. Thought it was a good idea to light it and take a whiff, life lesson!
Many thanks for this video. I have a old (maybe from 60's) ammonia absorption fridge. I intend to use a manual steel wire brush to remove a thin layer of rust on the evaporator tubes surface and then apply a thin layer of paint. Now I know how this test works. I will try to find this stick to test after brush task!
We use phenolphthalien solution as ammonia detector ,by taking any white paper soaked in solution that its colour goes to dark red when using with alkalines like ammonia.
Sulphur stick fumes are probably worst than ammonia itself, i had a lesson today while trying to find leaks over condenser unit, i cant stop coughing for atleast 15min...
In Germany we can buy these as "Schwefelschnitten", flat rectangular sulfur-soaked cardboard pieces. They're used for disinfection of barrels and other brewing equipment as well as for beekeeping equipment.
Snoop (and any other water based bubble detector) doesn't work to find an ammonia vapor leak as the ammonia has an affinity for water and just gets absorbed into the liquid rather than creating a bubble.
No. The sulfur-stick will only produce white smoke in the presence of ammonia. So you pass the stick over the joints, and if white smoke is produced, that means there's a leak, and if none is produced, then there is probably no leak
Ammonia is under pressure and takes special equipment to handle it. It's similar to "Freon" but will kill you, or at least hurt you. Ammonia is re-usable, that's what all the machinery is for. Here in Idaho we inject ammonia directly into the soil when planting wheat, when it enters the soil in turns into Nitrogen, which is a fertilizer
late response but, you can make it. Just buy any kind of sulphur(any drugstore), grind it and then heat it in something until it melts(do not burn it directly) and then soak any thread to make the stick. Wait till it cools down and its done

Have used the phenolphthalein trick to test secondary coolant for leaks from the primary NH3 coolant. It works well if you do it correctly.
Make sure there isn't a flammable gas leak first.
Ammonia gas isnt flammable😂
@@Manstobal I never said it was.
It depends on the concentration

You can get the sulfur sticks from your ammonia vendor.
Amazon has them as well by the 100 count.

I think working around any pressurized gas system with an open flame is probably a bad idea?
Only because you lack any knowledge.
Ammonia isn't concentrated enough (in this case) to be flammable
Hi! that white smoke was the actual gas leaking or reaction from ammonia and sulfur?
It es a reaction between SO² and NH³ to solid NH4SO4. This is visible as smoke.
Packing nut must of the times .
Surfactant & water (Liquid Snoop) on the fitting and look for bubbles. No Sulfur inhalation!!
Snoop (and any other water based bubble detector) doesn't work to find an ammonia vapor leak as the ammonia has an affinity for water and just gets absorbed into the liquid rather than creating a bubble.
That's pretty interesting. Do you look for the smoke to be disturbed by the escaping ammonia?
No. The sulfur-stick will only produce white smoke in the presence of ammonia. So you pass the stick over the joints, and if white smoke is produced, that means there's a leak, and if none is produced, then there is probably no leak
I forgot about commenting on this video until your reply. Between then and now I was hired as an Operator on a Huge Anhydrous Ammonia System.
Lab Rat that only works if it’s not on a suction line. Sulfur sticks and PH paper are the best ways to tell.
Ammonia + Sulphur = Ammonium Sulphate?
Acido acetico
Hi guys..is there a possible that i can re-use the ammonia liquid? If it's possible. how, and what should i do.

How to make that stick or where it is available ??
