Vessel with optimized purge gas flow and method using same
View Patent ↗A vessel for the storage and transportation of bulk volumes of a fluid is described herein and a method for using same. The vessel contains a plurality of dividers that apportion the internal volume into a number of sections. The dividers within the vessel aid in minimizing sloshing of the fluid contained therein during transport. In addition, the dividers optimize the fluid flow pattern thereby allowing for the continuous purge of the vessel without the need for the application of a partial or full vacuum.
1. A method for continuous purging of contaminants from a vessel, the method comprising:
providing the vessel comprising an internal surface, an internal volume, a plurality of dividers that apportions the internal volume into two end sections and an at least one center section wherein at least a portion of the dividers contacts the internal surface of the vessel thereby defining one or more apertures and wherein the one or more apertures within the dividers are substantially in alignment with respect to each other, an at least one fluid inlet that extends into the at least one center section, an at least one fluid outlet, and contaminants contained therein;
introducing a stream of gas into the vessel through the at least one fluid inlet wherein the gas flows into the at least one center section and through the top apertures of the dividers into the two end sections to form a contaminant-laden stream; and
removing the contaminant-laden stream from the vessel through the at least one fluid outlet.
2. The method of claim 1 wherein the at least one fluid outlet extends into the at least one center section.
3. The method of claim 1 wherein the at least one fluid outlet extends into an end section.
4. The method of claim 1 wherein the vessel is cylindrical shaped.
5. The method of claim 1 wherein the volume of the at least one center section and the end sections are substantially equal.
6. The method of claim 1 wherein the volume of the at least one center section ranges from about 33% to about 66% of the internal volume.
7. The method of claim 1 wherein the at least one fluid inlet is located on or around the midpoint between the pair of dividers.
8. A method for continuous purging of contaminants from a vessel, the method comprising:
providing the vessel comprising an internal surface, an internal volume, a plurality of dividers that apportions the internal volume into two end sections and an at least one center section wherein at least a portion of the dividers contacts the internal surface of the vessel thereby defining one or more apertures and wherein the one or more apertures within the dividers are substantially in alignment with respect to each other, an at least one fluid inlet and an at least one fluid outlet wherein the at least one fluid inlet and at least one fluid outlet are located within the at least one center section and are proximal to an area selected from top, bottom, east side, and west side of the vessel, and contaminants contained therein;
introducing a stream of gas into the vessel through the at least one fluid inlet wherein the gas flows into the at least one center section, through the apertures of the dividers that are opposite to the area wherein the at least one fluid inlet and at least one fluid outlet are located, and into the two end sections to form a contaminant-laden stream; and
removing the contaminant-laden stream from the vessel through the at least one fluid outlet.
9. The method of claim 8 wherein the area in the providing step is the bottom of the vessel and wherein the gas in the introducing step flows through the top apertures.
10. The method of claim 8 wherein the area in the providing step is the top of the vessel and wherein the gas in the introducing step flows through the bottom apertures.
11. The method of claim 8 wherein the area in the providing step is the east side of the vessel and wherein the gas in the introducing step flows through the west apertures.
12. The method of claim 8 wherein the area in the providing step is the west side of the vessel and wherein the gas in the introducing step flows through the east apertures.
