?? i SHOULD CHECK IF THERE IS A WAY TO oops
god DAMN that caps lock
increse the font size: I find the "non bold" really hard to read. WEELL not "really hard"
but the bold is better, and being a colored guy myself, I thought it might match my colorful self??? or something.

Osmium comes by and thunks me on the head, points and laughs, makes a comment or two and then comes back and amends his comments:
I understand: you can't ALWAYS be right when you are pontificating off the cuff:
AND,
despite his onery ways and masterful way with the quick and telling insult, he always leaves a little mard of truth buried in the LARGE pile of offal he leaves behind.
Kinda like the needle in a haystack: but at least THERE you could use a magnet: with HIS stuff you need a pitchfork, and a self contained breathing mask.
BUT if you wanna find the mards, the digging has to be done.
So Osmoidium accurately says that just because there is a signifcant differential between the vapor pressures and volatility of ammonia and water, that you can't have them both in a flask, and like SUCK on it and have the ammonia all come off before the water does.
The two molecules hold hands: ionically and maybe Van der Waals forces if my memory of such is still working after lo these many years.
You could probably go into a freezer and mix together 50/50 % ammonia /water and have the solution stay stable more or less when it was opened.
But 30% ammonia is the max (approx) you can get at normal temperatures.
HMM: Looks like the hotter the ammonia/water solution is the less ammonia it will hold. HYPOTHESIS ONE
A stable mixture of ammonia/water, when heated to say 80 C will be found to have a lower concentration of ammonia in it after you cool it down.
At that temperature an equilibrium is formed and the water and ammonia will be driven off at the same rate.
HOWEVER, and this is the key hypothesis to my plan: in VAPOUR phase, the molecules are relatively WAY FAR APART:
they have a greater chance of being operated on separately.
SO:
You bubble air while you slowly warm the aquous:
the vapour travels into a 30 meter long hose a little over 1 1/4 CM in diameter, having a volume of about 12,000CM^3 , and a surface area of about 2300 CM^2.
The impetus through this hose from the warming basin is an $8 aquarium air pump pushing an astounding 1200 CC per minute at an amazing 1.5 PSI. (Thus the vapour will spend a liesurely 10 minutes traversing the tube......)
The hose is coiled in a 5 gal bucket as previously described.
The bucket is filled with dry ice and alcohol, or colemans, or whatever.
The excited and relatively distant molecules, which were so close together that they ruined each others personality in the liquid phase, are now dancing more or less totheir own harmonics.
And the ice looking at those COLD walls, decides to tke up semi permanent crystal residency thereupon.
The ammonia sees the water as a wimpy self indulgent non ambitious lazy cold intolerant species< and trucks on UP the spiral coil looking for some REAL cold spots before taking a break.
Based on my experience with the great fertilizer experiment, I'll not soon revisit that boring hard work technique if this one works.
So if you clog up your ice maker line in the first ten feet:(rendering it inoperative) you shut off your pump, open the connection at the top, and dump in some warm or hot alcohol and collect it AND the melted ice water at the bottom.
By the way, if you measure the alcohol charges, and the combined exit fluids, you can infer what the concentration of the Nh3 in the condenser is. (THis assumes that mighty little of the NH3 gets entrained in the freezing ice. )
==========
The SECOND half of the condenser you may recall winds DOWNWARD in IT's bucket: (ALSO dry ice and alcohol surrounded)
the 1/4 " hose isabout ??110 t0 130 feet in this section.
It discharges into an ehrlinmyer with a starting charge of maybe 10CC alcohol.
The end of the hose should be sealed off, and the last 6" or so ought to be carefully multi-punctured with a hot needl to make numerous small holes for the NH3 gas to exit: The SMALL bubbles will be more efffectively cooled.....
Any selfish "better-than" hot rod smart aleck ammoniacal molecules that refuse to do the right thing and condense into a liquid find themselves REPLUMBED back intothe ENTRANCE side of the air pump where they have to rePEAT the process again: by such discipline we expect the NH3 to be Very well behaved. Nothing like being forced to go around in circles interminably to change your attitude.
(By the way, the air pumps I saw and bought were NOT inclusive of points and electical sparks: just a magnet on the end of an oscillating rod which depreses the diaphram: thus though it is not UL registered for expolive atmospheres, it will not likely be party to an explosion. )
(By the DOUBLE way, the little air pumps only have an OUT LINE built in:
Therefor you have to ENTOMB them in your favorite piece of you wifes plastic food storage ware, and SEAL the pump INSIDE: and plumb a RETURN line into the Tupperware...
(YEAH YEAH YEAH you have to cut a weensie hole for the electrical cod too: so what's the bigggee?)
===========
So you see that the inestimable Osmoid left this little terd of an idea when last he came to thump my head and point and laugh.
Despite his despicable demeanor:
Despite his demeaning dialogues
Despite his rude finger pointing and laughing and making fun of my nose:
Underneath: he's just really a nice guy and I know he REALLY loves me too.
Huh, Os??
dwarfer.
