Ammonia Transfer System

Our Ammonia Transfer System is designed for the off-loading of anhydrous ammonia from railcars or tank cars. The piping, valve arrangement, and program logic are based on the stringent safety standards used in the chlorine industry for the unloading of railcars (The Chlorine Institute Pamphlet 57).

The system is supplied as a complete unit with all controls and instrumentation pre-assembled, wired, and pressure tested. This simplifies installation significantly, potentially resulting in considerable savings in time and materials.

It is completely customizable to accommodate individual customer needs. The top line of the system is used for the ammonia coming from the railcar or tank car while the middle line is used to evacuate the line of ammonia before disconnecting it from the car. This line is pulled into a Powell Scrubber. The bottom line of piping is for padding ammonia vapor supply to the railcar or tank car using the Air Treatment System.
