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.
Claims22
A portable tank comprising an upper region, a middle region and a lower region wherein
- (a) the upper region is a cover body adjacent to and attached to the middle region and comprises an opening in the central region to provide a materials inlet;
- a first peripheral opening and a second peripheral opening provided at the periphery of the cover body wherein a gas inlet is attached to the first peripheral opening and a gas outlet is attached to the second peripheral opening and further wherein the gas inlet and gas outlet extend through the cover body;
- (b) the middle region and the lower region each comprise side walls and are continuous or connected such that the combination of the middle and lower regions define a cavity;
- (c) the middle region comprises a gas disperser connecting with the gas inlet, positioned within the cavity defined by the middle and lower regions along the internal side wall of the middle region wherein the gas disperser is constructed with a plurality of support rests positioned intermittently along the length of the gas disperser;
- and a clean out port mounted into the side wall of the middle region adjacent to the gas disperser;
- and
- (d) the lower region comprises a materials discharge outlet at its lower end.
A portable tank comprising an upper region, circular in shape, a middle region, cylindrical in shape and a lower region wherein
- (a) the upper region is a cover body adjacent to and attached to the middle region and comprises an opening in the central region to provide a materials inlet;
- a first peripheral opening and a second peripheral opening provided at the periphery of the cover body wherein a gas inlet is attached to the first peripheral opening and a gas outlet is attached to the second peripheral opening and further wherein the gas inlet and gas outlet extend through the cover body;
- (b) the middle region and the lower region each comprise side walls and are continuous or connected such that the combination of the middle and lower regions defines a cavity;
- (c) the middle region comprises a gas disperser positioned within the cavity defined by the middle and lower regions and along the internal side wall of the middle region wherein the gas disperser is constructed with a plurality of support rests positioned intermittently along the length of the gas disperser and is defined by an inner parallel wall facing the inside of the portable tank and exposed to the portable tank contents, and an outer parallel wall, wherein the walls are separated to define a gas region between the walls, wherein the gas inlet connects into the gas region, and further wherein the inner parallel wall comprises perforations;
- and one or more clean out ports mounted into the side wall of the middle region adjacent to the gas disperser;
- and
- (d) the lower region comprises a materials discharge outlet at its lower end.
