1. A vessel for treating a process stream, the vessel comprising:
a first processing zone containing a plurality of randomly packed processing materials;
a second processing zone containing a plurality of randomly packed processing materials; and
a redistribution zone located between the first processing zone and the second processing zone, the redistribution zone comprising a mix of both processing materials and treating elements, the treating elements having one or more openings formed therein or therethrough,
wherein the redistribution zone is directly adjacent to the first processing zone, and wherein the processing materials in the first processing zone are sized such that at least some of the processing materials can migrate into the redistribution zone to create a combo-zone having both processing zone functionality and treating zone functionality,
and wherein the processing materials comprise catalyst and the treating elements comprise a material other than the catalyst of the processing materials,
and wherein the treating materials are larger in size than the processing materials, and wherein the depth of the redistribution zone is less than the depth of the first processing zone and less than the depth of the second processing zone.
