A liquid ammonia pump-vapor stripper unit is disclosed having an impeller pump assembly which increases the system pressure before it is delivered to a receiver-accumulator where the ammonia vapor mass formed along its path from the storage tank is separated from the liquid and throttled across a variable area regulator formed between a regulator cone and a regulator ball and past a normally closed demand valve before the vapor mass is returned to the storage tank. The dew point of the liquid ammonia mass flowing through the unit is increased by the impeller pump due to the additional pressure added to the system, the liquid ammonia leaving the receiver-accumulator behaves more like a true liquid resulting in a more accurate downstream metering and a more efficient delivery of ammonia to the soil.

[ What is claimed is:] [1.] A vapor stripper assembly for removing a vapor from a flow mass of the vapor combined with a liquid, comprising:a receiver body having a receiver chamber with a receiver mass inlet for receiving the flow mass, a receiver liquid outlet, and a receiver vapor outlet;a vapor stripper including a variable area inverted regulator cone in fluid communication with the receiver vapor outlet of said receiver body, the variable area inverted outlet having a regulator cone vapor outlet, and a regulator ball positioned to operate within the variable area inverted regulator cone; andwherein the area around the regulator ball in the variable area inverted cone decreases as the regulator ball becomes in closer proximity to the regulator cone vapor outlet.
