'''Pneumatic Unloading Systems''' are commonly used to unload soda ash from railcars are used in a wide variety of applications. | |||
Pneumatic systems are best used for unloading rates below 25 tons per hour and when the storage tank can be located in close proximity to the rail unloading point. | |||
==Common Types== | |||
There are two basic types of pneumatic unloading packages, vacuum-positive pressure or | |||
positive pressure. The vacuum-positive pressure method, which uses a vacuum to puff soda ash | |||
from the car unit (which in turn uses positive pressure to blow product to storage) can be used | |||
with both the standard gravity discharge railcars and with railcars equipped for pneumatic | |||
unloading. The positive pressure method can be used with standard gravity discharge railcars | |||
and with pressure differential (PD) pneumatic railcars. These systems require readily available | |||
pneumatic transfer packages. FMC can assist in the selection of a vendor of such equipment. | |||
==Typical Advantages== | |||
*Low capital cost vs. mechanical systems | |||
*Flexible design and operating parameters | |||
*Less prone to water incursion and eliminates spurious dusting | |||
