ABSTRACT:
A container and method for transporting finely divided coal in rail cars or other cargo hauling vehicles, the container having a generally flexible and substantially oxygen impermeable barrier defining an encapsulated cavity. A port, including a coupling adapted to substantially prevent exposing the finely divided coal to oxygen, is positioned in the container for passing a flowable material through the barrier. The container also including a cap for sealing the port, a one-way pressure activated valve positioned in the barrier preventing gases in the cavity, and a harness for supporting the barrier and defining the shape of the cavity. The method generally having the initial steps of removing most of the oxygen from the cavity of the container, and adjusting the shape of the cavity to conform to the type of rail car that is being used to haul the finely divided coal. The method having the additional steps of filling the container with finely divided coal at a centralized collection site; sealing the container to substantially prevent introducing oxygen into the coal; loading the filled container into a rail car; hauling the container to a location where finely divided coal is used; unloading the container at the coal burning facility; and emptying the finely divided coal from the container at a location where the coal is used.
