The tank diameter was 48 m to the outer edge of the For this method of delivery, the storage tank must be at a lower level than the delivery unit and be equipped with a scrubber or vent system to allow for lower pressures to be maintained throughout the delivery process. Ammonia is refrigerated to -28┬ F by terminal storage tanks. Systems should be designed so that the pump is as near to the hose connection as possible and that the hose length required will be as short as possible, eighteen feet or less. To minimize potential ammonia leakage, the tanks utilize a double-wall design.
