[massad]

I have a question regarding Liquid Ammonia

Can any one tell me the properties of Liq. ammonia . At which temperature amonia is in liquid state . Furter what should be the requirements of making a vessel to store liquid ammonia . Is there are any particular requirements ?? If any one can share relevent literature that would be helpfull


Thakyou and Regards

The web site below is a good one for starters on handling ammonia. Your vessel will be a pressure vessel and as such needs to be designed to a recognized code of construction (like ASME Boiler and Pressure Vessel Code). Read up on this topic, it is very important to understand the hazards of dealing with ammonia.

I'm going on memory at this point, but all of the liquid ammonia preesure vessels w/o refrigeration) that I have designed per ASME VIII had an MAWP of 250 psig at a design temp of 150F. I believe that most, if not all, were also PWHTd.

They built a huge ammonia tank near my hometown a number of years back. I assume it is refrigerated, as it is a flat-bottom tank. A similar tank here:

I did a tank vent project some years back for liquid ammonia storage tanks at an ammonia plant, and I seem to remember them being the aluminum "Protectoseal" standard product.
