Liquid ammonia filling issues
Thread Content
Fill a 900L bottle with liquid ammonia; at a rate of 20L per hour, as the liquid ammonia is added, the pressure inside the bottle will equalize with the pressure in the tower, making it difficult to continue filling it. What should be done if one wants to cool the bottle to around -33 degrees Celsius, the boiling point of ammonia?
Invert the liquid ammonia cylinder, and feed material from the bottom into the 900L container with its upper opening open; this way, the container can be filled to capacity.
There’s no need to cool it down; you just need to connect your container to what you call a tower using a liquid-phase pipe (it’s not clear what exactly this means – an ammonia storage tower?) (Haven’t heard of it) Connect them, and use a vapor line to link the vapor phase of your container to that of the tower; place your container below the ammonia liquid phase line in the tower, and make sure your container is filled with liquid ammonia. The so-called pressure balance you’re referring to should mean there are no gas pipes, so liquid ammonia can’t get into the container. Also, as a safety reminder, the container should not be filled to capacity with liquid ammonia; 80% or less is sufficient.
