Powell Ammonia Control Module
The Powell Ammonia Control Module is designed for the off-loading of anhydrous ammonia
from railcars. The piping, valve arrangement, and program logic are based on the
stringent safety standards used in the chlorine industry for the unloading of railcars
(Chlorine Institute Pamphlet 57).
The Powell Ammonia Control module is completely customizable to accommodate individual
customer needs. In the configuration displayed in the photo below, the top
line is used for the ammonia coming off of the railcar while the second line is
used to evacuate the line of ammonia before disconnecting it from the car. This
line is pulled into an ammonia scrubber. The bottom line of piping is for padding air supply to the railcar.
