US 2025/0091020 A1 · FLUID DISTRIBUTOR AND UP-FLOW REACTORS

Abstract

A fluid distributor is provided for distributing a fluid in an up-flow reactor. The fluid distributor includes a supply pipe and a plurality of fluid distribution arms that extend from the supply pipe. Each of the fluid distribution arms has a plurality of holes for discharging the fluid. An elongated hood is spaced from and at least partially surrounds each of the fluid distribution arms to redirect the fluid when discharged from the plurality of holes in the fluid distribution arms. Each hood has a plurality of holes for allowing the passage of the fluid through the hood. Each of the hoods is formed from a plurality of hood segments that positioned end to end along a length of the fluid distribution arm and have deflectors to impede the fluid from flowing between adjacent ones of the hood segments.

Dependent claims

A fluid distributor for distributing a first fluid in an up-flow reactor, said fluid distributor comprising:

a supply pipe and a plurality of fluid distribution arms that extend from the supply pipe, each of the fluid distribution arms having a plurality of holes for discharging the first fluid when the first fluid is within the fluid distribution arms and is under pressure;
an elongated hood overlaying and spaced from and at least partially surrounding each of the fluid distribution arms and constructed to redirect the first fluid when discharged from the plurality of holes in the fluid distribution arms, each hood having a plurality of holes for allowing the passage of the first fluid through the hood, each of the hoods comprising a plurality of hood segments positioned end to end along a length of the fluid distribution arm and having deflectors to impede the first fluid from flowing between adjacent ones of the hood segments.

A two-phase, co-current, up-flow reactor comprising:

a shell defining an open internal region;
a first fluid inlet and a second fluid inlet positioned in a lower region of the shell for introducing a first fluid and a second fluid, respectively, within the shell;
a first fluid outlet and a second fluid outlet positioned in an upper region of the shell for removing the first fluid and the second fluid, respectively, from within the shell;
spaced-apart coplanar lower support beams connected to the shell and extending chordally across the open internal region;
a catalyst support grid positioned above and supported by the coplanar lower support beams;
a catalyst hold-down baffle spaced above the support grid and having a central impermeable area that defines an annular flow path for the first and second fluids through the catalyst hold-down baffle in a region between the central impermeable area and an inner surface of the shell;
spaced-apart coplanar upper support beams connected to the shell and extending chordally across the open internal region and supporting the catalyst hold-down baffle;
an annular trough supported above the coplanar upper support beams and spaced inwardly from the inner surface of the shell for receiving the second fluid after ascending through the annular flow path;
a central open region defined by the annular trough and into which the second fluid enters after overflowing the annular trough;
and
an intake pipe for the second fluid and having an inlet end spaced above the central impermeable area and extending upwardly to the second fluid outlet for removing the second fluid from the central open region.
