A method for facilitating the distribution of the flow of one or more streams within a bed vessel is provided. Disposed within the bed vessel are internal materials and structures including multiple operating zones. One type of operating zone can be a processing zone composed of one or more beds of solid processing material. Another type of operating zone can be a treating zone. Treating zones can facilitate the distribution of the one or more streams fed to processing zones. The distribution can facilitate contact between the feed streams and the processing materials contained in the processing zones.

The method of claim 1, wherein the redistribution treating zone has a depth of one foot or less. 3. The method of claim 1, wherein the redistribution treating zone has a depth of two feet or less. 4. A method of improving flow distribution of one or more streams in a process vessel comprising: passing the one or more streams through an upstream processing zone and a downstream processing zone within the process vessel, the upstream processing zone and downstream processing zone each containing one or more beds of processing materials; andpassing the one or more streams through a redistribution treating zone located between the upstream processing zone and downstream processing zone, wherein the redistribution treating zone contains a plurality of treating elements and wherein the redistribution treating zone mitigates stream channeling of the streams exiting the upstream processing zone and affects lateral redistribution of the flow of the one or more streams within the downstream processing zone,and wherein the process vessel does not utilize a structured, engineered device within the processing vessel adjacent the redistribution treating zone—to facilitate flow distribution,and wherein the redistribution treating zone is adjacent to the upstream processing zone and a permeable membrane is disposed between the treating elements in the redistribution treating zone and the processing materials in the upstream processing zone such that the processing materials from the upstream processing zone cannot migrate into the redistribution treating zone but the stream flow may pass through the membrane. 5. A method of improving flow distribution of one or more streams in a process vessel comprising: passing the one or more streams through an upstream processing zone and a downstream processing zone within the process vessel, the upstream processing zone and downstream processing zone each containing one or more beds of processing materials; andpassing the one or more streams through a redistribution treating zone located between the upstream processing zone and downstream processing zone, wherein the redistribution treating zone contains packed treating elements and wherein the redistribution treating zone mitigates stream channeling of the streams exiting the upstream processing zone and affects lateral redistribution of the flow of the one or more streams within the downstream processing zone,and wherein no structured, engineered device separates the upper portion of the redistribution treating zone from the lower portion of the upstream processing zone,and wherein the redistribution treating zone is directly adjacent to the upstream processing zone and certain of the processing materials from the upstream processing zone are mixed into the redistribution treating zone during loading of the process vessel to create a combo-zone having both processing zone functionality and treating zone functionality. 6.

The method of claim 5, wherein one or more of the treating elements have one or more asperities formed on the surfaces thereof. 19. The method of claim 18, wherein asperities comprise one or more of flutes, fins, struts, filaments, spikes or hairs. 20. A method of improving flow distribution of one or more streams in a process vessel comprising: passing the one or more streams through an upstream processing zone and a downstream processing zone within the process vessel, the upstream processing zone and downstream processing zone each containing one or more beds of processing materials; andpassing the one or more streams through a redistribution treating zone located between the upstream processing zone and downstream processing zone, wherein the redistribution treating zone contains packed treating elements and wherein the redistribution treating zone mitigates stream channeling of the streams exiting the upstream processing zone and affects lateral redistribution of the flow of the one or more streams within the downstream processing zone,and wherein no space between the upstream processing zone and the redistribution treating zone is consumed by a structure internal to the process vessel,and wherein the redistribution treating zone is directly adjacent to the upstream processing zone and the processing materials in the upstream processing zone are sized such that at least some of the processing materials can migrate into the redistribution treating zone to create a combo-zone having both processing zone functionality and treating zone functionality. 21.
