Transportation subassembly for materials destabilized in presence of destabilizing contaminants
A transportation subassembly is provided for transporting a material that is destabilized in the presence of a destabilizing contaminant. The subassembly has a structural body having a cavity constructed and arranged to receive the material to be stored, a breather assembly operatively connected to the structural body and including a container forming a chamber, the chamber being in fluidic communication with the cavity and being constructed and arranged to receive an contaminant-removing material selected to remove the destabilizing contaminant, and a venting assembly mounted with respect to the structural body. The venting assembly includes a rupture apparatus rupturable at a predetermined pressure formed within the cavity to form fluidic communication between the cavity and the atmosphere. A method for transporting a material in a transportation subassembly is also provided. A structural body having a cavity for storing the material to be transported and a rupture apparatus rupturable at a pressure formed within the cavity is used. The method includes inspecting the cavity for defects and for destabilizing impurities; dry air purging the cavity; loading the material into the cavity; activating a breather assembly to restrict destabilizing impurities from within the cavity; operatively connecting a dry air line to the cavity to form fluidic communication between the cavity and the storage compartment; and maintaining the breather assembly in an activated position to maintain the cavity in a pure condition.
1. A method for transporting a material that is destabilized in the presence of a destabilizing contaminant, the method comprising:
selecting a transportation subassembly comprising a structural body having forming a cavity constructed and arranged to receive the material and having a rupture apparatus rupturable at a predetermined pressure formed within the cavity to form fluidic communication between the cavity and the atmosphere;
inspecting the cavity for defects and for presence of the destabilizing contaminant;
dry air purging the cavity;
loading the material into the cavity;
activating a breather assembly to restrict the destabilizing contaminant from within the cavity;
transporting the material to a desired location having a storage compartment;
operatively connecting a dry air line to the cavity to form fluidic communication between the cavity and the storage compartment;
unloading the material into the storage compartment; and
maintaining the breather assembly in an activated position to maintain the cavity in a destabilizing contaminant-free condition.
2. A method for temporarily storing and transporting sodium percarbonate in a railcar comprising a structural body having a hopper forming a cavity for storing the sodium percarbonate and an inverted rupture disc mounted to the hopper and rupturable at a pressure formed within the cavity, the method comprising the steps of:
inspecting the hopper for defects and the cavity for moisture;
dry air purging the cavity;
loading the sodium percarbonate into the cavity;
activating a breather assembly to restrict moisture from within the cavity;
transporting the sodium percarbonate to a desired location having a storage compartment;
operatively connecting a dry air line to the at least one hopper to form fluidic communication between the cavity and the storage compartment;
unloading the sodium percarbonate into the storage compartment; and
maintaining the breather assembly in an activated position to maintain the cavity in a dry condition.
