Ammonia purging

[Grizzly]

The below diagram is from a 1973 J&E Hall Info / defect Bulletin.

Stating that in order to eliminate the possibility of introducing water into the compressor.
Because as the pressure inside the crankcase of the compressor falls to ambient. The rate of absorption reduces the pressure in the crankcase very rapidly
and water will enter the crankcase. (Yep been there!)

The preferred solution is outlined below:-




Explanation:-
The gas should be vented into an enclosed vessel with a further outlet into a water container.
The amount of water in the container would be less than that required to fill the enclosed vessel. This would then make it impossible for water to enter the crankcase.

I have seen this type of arrangement recommended before but as yet don't know of anyone that applies it.
Does anyone actually use anything like this out in the field?
