| DWPI Title: Media-free filter device for supercritical fluid process, has y-pipe section inducing eddy current turbulence zone adjacent intersection joint remove all contaminants suspended in supercritical fluid and are deposited in descending segment |
| Abstract: A media-free filter device for a supercritical fluid process is disclosed. The media-free filter device includes a first pipe section connected in flow communication with a closed-loop system for a supercritical fluid. A y-pipe segment intersects the first pipe section at an intersection joint. The intersection joint intersects at a descending obtuse angle with respect to the first pipe section flow direction. The y-pipe segment is open at the intersection joint and closed opposite the intersection joint, in flow communication with the first pipe section. The y-pipe section induces an eddy current turbulence zone adjacent the intersection joint to remove substantially all contaminants suspended in the supercritical fluid; and the contaminants are deposited in the descending y-pipe segment. An SCO2 process incorporating the media-free filter device is also disclosed. |
| Use: Media-free filter device of closed loop system (claimed) for supercritical fluid process. |
| Advantage: The low pressure drop and contaminant filtration is achieved through a filter that uses swirl technology. The use of the swirl technology in a y-pipe trap to replace media filters create pressure drops and reduce system efficiency. The low pressure drop associated with Y-pipe acting as filter allows for a greater number of Y-traps throughout the closed loop system. The overall system efficiency is maintained at a high level with significantly less, nearly negligible losses. |
| Novelty: The media-free filter device has a first pipe section (100) connected in flow communication with a closed-loop supercritical fluid system. A y-pipe segment is intersecting the first pipe section at an intersection joint is at a descending obtuse angle with respect to the first pipe section flow direction. The y-pipe segment opens at the intersection joint and closed opposite the intersection joint in flow communication with the first pipe section. The y-pipe section inducing an eddy current turbulence zone is adjacent the intersection joint removes all contaminants suspended in the supercritical fluid which comprises a supercritical carbon dioxide (SCO2) fluid, and the contaminants are deposited in the descending y-pipe segment. |
