Default ammonium hydroxide in a sealed tank



I have a 100 liter chemical processing tank that is about 1/5th filled
with 20%(wt) ammonium hydroxide. I want to be able to seal the tank so
the loss of ammonia is minimized. My problem is that a sealed tank
undergoes large shifts in pressure due to the both solubility of
ammonia in water and its vapor pressure changing with temperature.
This pressure change in enough to distort the tank. If a bleed hole
installed then ammonia will be lost on each temperature rise. i.e.
from morning to evening during the day. I once had a old drum of
ammonia hydroxide that was only partly filled and it turn into water
about a year later because of the bleed hole.

Does anyone know if some type of sealed bags are available that
connect to the tank via a hose. The bag should then inflate/deflate
with temperature thus remaining at atmospheric pressure.

You need a sealed system or ammonia will leak no mather what. To make
it less pressurised, you can use a cold storage (refrigerate to modest
temp, say 5C)
