Abstract
Abstract A solid-fluid contacting apparatus, comprising an outer generally tubular housing member, preferably cylindrical in shape; an inner generally tubular housing member defining a fluid flow channel therein and being placed inside of the outer housing member and being generally coaxially aligned therewith, preferably concentrically, to define a space therebetween, preferably an annular space; at least one means extending radially between the inner and outer housing members for partitioning the space into a plurality of axially spaced contacting zones; at least one means extending axially within the inner housing member for partitioning the fluid flow channel into a plurality of fluid flow sub-channels; means in each of the contacting zones for receiving the solid; and a fluid flow inlet communicating between each of the subchannels and one of the contacting zones, a fluid flow outlet communicating between each of the contacting zones and its respective subchannel, and means positioned in each subchannel between the inlet and outlet for preventing fluid flow through the sub-channel.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
246 words
An apparatus for contacting a fluid with a solid material contained in a plurality of independent contacting units within the apparatus, comprising: a. an outer generally tubular housing member; b. an inner generally tubular housing member defining a fluid flow channel therein and being placed inside of said outer housing member and being generally coaxially aligned therewith to define a space therebetween; c. at least one means extending radially between said inner and outer housing members for partitioning said space into a plurality of separate, axially spaced contacting zones; d. at least one means extending axially within said inner housing member for partitioning said fluid flow channel into a plurality of fluid flow sub-channels, corresponding in number to the number of said contacting zones; e. means within each of said contacting zones for receiving said solid; and f. at least one fluid flow inlet and at least one fluid flow outlet, said inlets and outlets corresponding in number to the number of said contacting zones, and each of said inlets and outlets connecting a single one of said contacting zones to a single one of said sub-channels, and means positioned in each sub-channel between said inlet and outlet for preventing fluid flow through said sub-channel such that each contacting zone, and its respective sub-channel, fluid flow inlet and outlet define a contacting unit independent from other such contacting units wherein each of said sub-channels forms an exclusive supply and discharge passage for its respective contacting zone.
Claim 2
Independent Claim
246 words
An apparatus for contacting a fluid with a solid material contained in a plurality of independent contacting units within the apparatus, comprising: a. an outer generally tubular housing member; b. an inner generally tubular housing member defining a fluid flow channel therein and being placed inside of said outer housing member and being generally coaxially aligned therewith to define a space therebetween; c. at least one means extending radially between said inner and outer housing members for partitioning said space into a plurality of separate, axially spaced contacting zones; d. at least one means extending axially within said inner housing member for partitioning said fluid flow channel into a plurality of fluid flow sub-channels, corresponding in number to the number of said contacting zones; e. means within each of said contacting zones for receiving said solid; and f. at least one fluid flow inlet and at least one fluid flow outlet, said inlets and outlets corresponding in number to the number of said contacting zones, and each of said inlets and outlets connecting a single one of said contacting zones to a single one of said sub-channels, and means positioned in each sub-channel between said inlet and outlet for preventing fluid flow through said sub-channel such that each contacting zone, and its respective sub-channel, fluid flow inlet and outlet define a contacting unit independent from other such contacting units wherein each of said sub-channels forms an exclusive supply and discharge passage for its respective contacting zone.
