| 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. |
