Abstract: A transportable portable tank for storing, transporting and drying a hygroscopic material and a transportable portable tank assembly. The portable tank comprises an upper, a middle and a lower region. The upper region comprises a materials inlet, a gas inlet and a gas outlet. The middle region comprises a gas disperser. The lower region comprises a materials discharge outlet. The portable tank has a capability to effectively remove and/or exclude moisture and a capability to effectively break up agglomerates of caked hygroscopic material, such as iodine. The present invention further provides a process for drying a hygroscopic material such as iodine within a portable tank.
