No. It can’t compress back into a liquid. When we are loading they are only shoving liquid into the bottle and a high pressure through the splash fill fitting. No vapor recovery hose is attached. The terminal is storing the ammonia in a true liquid state. They heat the liquid up to ambient temperature before it hits our tank. The higher pressure compresses the vapor into liquid. Inside the tank there is a standpipe up to the 85% fill level. They do this for speed and to keep tanks loading evenly because they are all lifting liquid to the same level. Without the standpipe the fuller trucks wouldn’t fill as fast as the one newly hooked up. The tanks would need to equalize to pump evenly.
