Abstract
A device for filtering and settling entrained particles from a gas feed stream, the device comprising a cylindrical v-wire filter element to filter the entrained particles, a cap located above the v-wire filter element comprising an outer surface, an under surface, and a downward rim attached to a perimeter of the under surface, and an open annulus area located between and in fluid communication with an open top portion of the v-wire filter element and the under surface of the cap.
Claims16
A device for filtering and settling entrained particles from a gas feed stream, the device comprising:
- a cylindrical v-wire filter element to filter the entrained particles, wherein the v-wire filter element comprises a solid metal ring and a body, wherein the solid metal ring is mounted on a top portion of the body to form a hollow internal passageway of the v-wire filter element, wherein the body comprises slits, wherein a first portion of gas stream flows radially through the slits to form a filtered gas stream, and wherein the hollow internal passageway receives the filtered gas stream;
- a cap located above the v-wire filter element comprising an outer surface, an under surface, and a downward rim attached to a perimeter of the under surface, wherein a bottom edge of the rim is aligned with a bottom edge of the solid metal ring;
- and
- an open annulus area located between and in fluid communication with an open top portion of the v-wire filter element and the under surface of the cap, wherein a second portion of gas feed stream flows upward along a length of the v-wire filter element, into the open annulus area and downward into the hollow internal passageway.
A gas-phase settling (GPS) tray installed within a catalytic reactor, the GPS tray comprising:
- a plurality of devices for trapping entrained particles from an inlet gas feed stream by particle filtration and settling, wherein each device comprises:
- a cylindrical v-wire filter element to filter the entrained particles, wherein the v-wire filter element comprises slits and a hollow internal passage, wherein a first portion of gas stream flows radially through the slits to form a filtered gas stream, and wherein the hollow internal passage receives the filtered gas stream;
- a cap located above the v-wire filter element and comprising an outer surface and an under surface;
- and
- an open annulus area located between and in fluid communication with an opentop portion of the v-wire filter element and the under surface of the cap, wherein a second portion of gas feed stream flows upward along a length of the v-wire filter element, into the open annulus area and downward into the hollow internal passage;
- and
- a planar surface comprising a plurality of panels, wherein each panel comprises an opening, and wherein the hollow internal passage of each device is located above and aligned with the opening of the panel.
A method for removing entrained particles from an inlet gas feed stream flowing into a catalytic reactor, the method comprising:
- (a) flowing the inlet gas feed stream into a top inlet of the catalytic reactor;
- and
- (b) subjecting the inlet gas feed stream to a gas-phase settling (GPS) tray installed within the catalytic reactor, the GPS tray comprising:
- a plurality of devices for trapping entrained particles from an inlet gas feed stream by particle filtration and settling, wherein each device comprises:
- a cylindrical v-wire filter element to filter the entrained particles, wherein the v-wire filter element comprises slits and a hollow internal passage, wherein a first portion of gas stream flows radially through the slits to form a filtered gas stream, and wherein the hollow internal passage receives the filtered gas stream;
- a cap located above the v-wire filter element and comprising an outer surface and an under surface;
- and
- an open annulus area located between and in fluid communication with an open top portion of the v-wire filter element and the under surface of the cap, wherein a second portion of gas feed stream flows upward along a length of the v-wire filter element, into the open annulus area and downward into the hollow internal passage;
- and
- a planar surface comprising a plurality of panels, wherein each panel comprises an opening, and wherein the hollow internal passage of each device is located above and aligned with an opening of the panel.
