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.
