Abstract
A railroad tank car can be filled with a slurry of a solid and a solvent therefor. The tank car is fitted with a feed distribution header that is provided with a plurality of predetermined spaced openings. The header is mounted in the car so that after the solids have settled, the solids are located below the distribution header and the supernatant liquid is above the distribution header. The supernatant liquid can then be withdrawn from the tank car through the distribution header and flows back to a storage tank from where it came. All of this can be accomplished with a single pump. Removing or unloading of solids from the car is effected by rendering the solids flowable with a liquor and pumping the solids from the car or dissolving them.
